Viral Gastroenteritis Treatment in Missouri (Stomach Flu)
Missouri adult care by secure video visit, self pay option starting at $49, MD-only, insurance is not required.
Viral gastroenteritis, commonly called the stomach flu, is an infection of the intestines that causes nausea, vomiting, diarrhea, and abdominal cramping. It is one of the most common acute illnesses in adults and is caused by viruses such as norovirus, rotavirus, and adenovirus. Most cases are self-limiting and resolve within 1 to 3 days with proper hydration and rest, but dehydration, severe vomiting, and the need for prescription anti-emetics can make timely medical evaluation valuable. TeleDirectMD uses a safety-first telehealth approach to screen for red flags including severe dehydration, bloody diarrhea, high fever, and signs of a more serious abdominal condition before determining whether an MD video visit is appropriate. If the history supports uncomplicated viral gastroenteritis without red flags, guideline-based supportive care and anti-emetic prescriptions such as ondansetron may be reasonable by video, while adults with signs of severe dehydration, bloody diarrhea, or suspected bacterial cause are directed to urgent in-person care. This page is for adults located in Missouri, including Kansas City, St. Louis, Springfield, Columbia, Independence, Lee's Summit, O'Fallon, St. Joseph, St. Charles, Blue Springs, and surrounding areas.

How Online Viral Gastroenteritis Treatment Works in Missouri
Book your video visit and prepare key details
Insurance is not required. No referral needed. Many visits are available same day, depending on scheduling. Before your visit, note when your symptoms started, the character of your diarrhea (watery vs. bloody), how many episodes of vomiting you have had, whether you can keep any fluids down, the presence of fever, recent travel or sick contacts, any antibiotics taken recently, and your overall fluid intake and urine output.
See a Missouri licensed MD by video
The MD reviews your symptom pattern, onset and duration, hydration status, fever, stool character, sick contacts, travel history, recent antibiotic use, immune status, and any red flags. The evaluation focuses on distinguishing uncomplicated viral gastroenteritis from conditions that require urgent in-person care, such as bacterial gastroenteritis, C. diff, appendicitis, or severe dehydration requiring IV fluids.
Get a treatment plan and, if appropriate, a prescription
If medication is clinically appropriate, we send an e-prescription such as ondansetron (Zofran) for nausea and vomiting to common Missouri pharmacies such as CVS Pharmacy, Walgreens, Walmart Pharmacy, Schnucks Pharmacy, Hy-Vee Pharmacy. You receive clear oral rehydration guidance, dietary instructions, and specific follow-up steps — including when to seek in-person care if symptoms worsen or do not improve.
Missouri Telehealth Regulations for Online Viral Gastroenteritis Care
Missouri Revised Statutes Section 191.1145 defines and regulates telehealth services, permitting licensed providers to deliver care via audio-video and other telecommunications technologies. The Missouri Board of Registration for the Healing Arts authorizes providers to establish a patient-provider relationship through telehealth without requiring a prior in-person visit.
Location matters: you must be physically in Missouri during the visit. Insurance is not required. TeleDirectMD does not prescribe controlled substances.

What Is Viral Gastroenteritis?
Viral gastroenteritis is an infection of the intestines caused by viruses, most commonly norovirus, rotavirus, adenovirus, and astrovirus. It is commonly but incorrectly called the 'stomach flu' — influenza viruses affect the respiratory system and do not cause gastroenteritis. The illness causes inflammation of the stomach and intestines, leading to nausea, vomiting, watery diarrhea, abdominal cramping, and sometimes low-grade fever. Symptoms typically begin 12 to 48 hours after exposure and resolve within 1 to 3 days for most adults, though some cases last up to a week.
Norovirus is the most common cause of viral gastroenteritis in the United States, responsible for 19 to 21 million cases of diarrheal illness annually and approximately 103,000 hospitalizations per year. It spreads easily via the fecal-oral route, through contaminated food or water, and by contact with infected surfaces. Outbreaks are common in schools, nursing homes, cruise ships, and other congregate settings. Rotavirus, once the most common cause in children, has become less prevalent in vaccinated populations. The illness is usually self-limiting in otherwise healthy adults, but dehydration is the most important complication and can be severe in older adults, immunocompromised individuals, and those who cannot tolerate oral fluids.
TeleDirectMD evaluates adults with stomach flu symptoms that are consistent with uncomplicated viral gastroenteritis and without red flags. The telehealth visit focuses on assessing hydration status, reviewing stool character and fever pattern, screening for alternative diagnoses, and providing evidence-based guidance on oral rehydration and anti-emetic prescriptions when appropriate. Adults with bloody diarrhea, high fever, severe dehydration, severe abdominal pain, or signs of a surgical emergency are directed to urgent in-person care.
Causes and Risk Factors
Viral gastroenteritis is caused by several different viruses that invade the intestinal lining, disrupt fluid absorption, and trigger the body's inflammatory response. Understanding common causes and risk factors helps determine whether a telehealth evaluation is appropriate or whether in-person assessment is needed.
- Norovirus: the most common cause of viral gastroenteritis in all age groups; highly contagious; spreads via contaminated food, water, or surfaces; responsible for approximately 50% of all foodborne illness outbreaks in the United States
- Rotavirus: historically the most common cause in young children; now less prevalent due to vaccination; can still affect unvaccinated adults and cause outbreaks in institutional settings
- Adenovirus and astrovirus: less common viral causes that can affect adults as well as children, particularly in institutional settings and among immunocompromised individuals
- Contaminated food or water exposure: undercooked shellfish, fresh produce, or water from contaminated sources; travel to areas with poor sanitation increases risk
- Close contact with ill individuals: viral gastroenteritis spreads easily in households, day cares, schools, nursing homes, and other congregate environments through direct contact and fomites
- Immunocompromised status: adults with weakened immune systems from illness, medications, or chemotherapy may experience more severe symptoms, prolonged viral shedding, and higher risk of complications requiring in-person care
Not every case of nausea, vomiting, and diarrhea is viral gastroenteritis. Bacterial gastroenteritis, C. diff, food poisoning from toxin-producing bacteria, appendicitis, and bowel obstruction can all cause overlapping symptoms. TeleDirectMD uses symptom patterns, stool character, fever pattern, and risk history to screen for alternative diagnoses and direct higher-risk cases to in-person care.
Symptoms and Red Flags for Viral Gastroenteritis in Missouri
Use this table to understand which symptoms are consistent with uncomplicated viral gastroenteritis appropriate for telehealth and which symptoms suggest a need for urgent in-person evaluation.
| Symptom or situation | What it suggests | Telehealth appropriate? | Red flag requiring urgent in-person care |
|---|---|---|---|
| Watery diarrhea (non-bloody), nausea, vomiting, abdominal cramping | Uncomplicated viral gastroenteritis is most likely | Often yes | If unable to keep any fluids down for 12+ hours or signs of dehydration develop |
| Low-grade fever (below 101°F) with GI symptoms | Consistent with viral gastroenteritis — mild fever is common | Often yes | If fever rises above 102°F with severe abdominal pain or bloody stool |
| Bloody or black tarry stools | Suggests bacterial gastroenteritis, C. diff, IBD flare, or other serious cause — not typical viral gastroenteritis | No | Always requires in-person evaluation |
| Fever above 102°F with abdominal pain | Raises concern for bacterial infection, appendicitis, diverticulitis, or other serious cause | No | Urgent in-person care or ER |
| Severe, localized abdominal pain or rigid abdomen | May indicate appendicitis, bowel obstruction, or surgical emergency | No | ER evaluation needed |
| Signs of significant dehydration (dizziness on standing, no urine output for 8+ hours, extreme dry mouth, confusion) | Dehydration may require IV fluids beyond what telehealth can manage | No | Urgent care or ER for IV rehydration |
| Inability to keep any fluids down for 12 or more hours | Risk of clinically significant dehydration — IV fluids may be needed | No | Urgent care or ER |
| Symptoms lasting more than 7 to 14 days | Suggests possible bacterial, parasitic, or chronic GI cause — not typical acute viral gastroenteritis | Sometimes, for guidance and referral | In-person evaluation for stool studies and further workup |
Differential Diagnosis: Viral Gastroenteritis vs Other Conditions
Many conditions can mimic viral gastroenteritis. Because treatment and urgency differ significantly, TeleDirectMD carefully reviews stool character, fever pattern, symptom duration, travel history, antibiotic use, and immune status to distinguish uncomplicated viral illness from conditions that require in-person evaluation or targeted therapy.
Sometimes Appropriate for Telehealth Guidance
- Classic uncomplicated viral gastroenteritis — watery diarrhea, nausea, vomiting, cramping without red flags
- Mild dehydration with ability to tolerate oral fluids — oral rehydration guidance and anti-emetic support
- Suspected norovirus or adenovirus illness in the context of known outbreak or ill contacts
- Over-the-counter medication guidance including bismuth subsalicylate and loperamide when safe
- Discussion of when to escalate to urgent in-person care and what to watch for
Often Requires In-Person Evaluation
- Bloody or black tarry diarrhea suggesting bacterial gastroenteritis, C. diff, or IBD flare
- Suspected Clostridioides difficile (C. diff) — especially in patients with recent antibiotic use, hospitalization, or healthcare exposure
- Severe dehydration unable to tolerate oral fluids — needs IV hydration and monitoring
- Suspected appendicitis — right lower quadrant pain with fever, nausea, and anorexia
- Suspected bowel obstruction — abdominal distension, no bowel movements, significant pain
- Immunocompromised patients with worsening or prolonged symptoms who may have atypical or severe infections
Viral vs Bacterial Gastroenteritis
Viral gastroenteritis typically causes watery (non-bloody) diarrhea, nausea, and vomiting, often with ill contacts, lasting 1 to 3 days. Bacterial gastroenteritis more often causes bloody diarrhea, high fever (above 102°F), and more severe illness lasting longer than 3 days. ACG guidelines do not recommend empiric antibiotics for community-acquired diarrhea when viral origin is suspected. Bloody stool, high fever, or recent travel to areas with high bacterial risk should prompt in-person evaluation.
Viral Gastroenteritis vs Appendicitis
Viral gastroenteritis typically causes diffuse, crampy abdominal pain that comes and goes with diarrhea and vomiting. Appendicitis classically causes progressive right lower quadrant pain that worsens over hours, often with fever and anorexia. If abdominal pain is severe, localized, or worsening rather than intermittent and diffuse, or if vomiting precedes diarrhea and is followed by pain that migrates to the right lower quadrant, in-person evaluation is needed urgently.
Viral Gastroenteritis vs C. diff
Clostridioides difficile (C. diff) colitis can cause watery or bloody diarrhea that mimics viral gastroenteritis but requires specific antibiotic treatment rather than supportive care. C. diff should be suspected in adults who have taken antibiotics within the past 8 weeks, have been recently hospitalized, or have had healthcare facility exposure. Patients with these risk factors and current GI symptoms should be directed to in-person evaluation and stool testing rather than telehealth management.
If your symptoms do not fit uncomplicated viral gastroenteritis, if any red flags are present, or if the diagnosis is uncertain, TeleDirectMD will direct you to the appropriate level of in-person care rather than manage you by video.
When Is a Video Visit Appropriate?
When a Video Visit Is Appropriate
- Watery (non-bloody) diarrhea, nausea, vomiting, or abdominal cramping consistent with viral gastroenteritis
- Symptoms onset within the past 1 to 7 days
- No fever above 102°F
- Able to keep at least small sips of fluid down
- No bloody or black tarry stools
- No severe, localized abdominal pain or rigid abdomen
- No recent antibiotic use or hospitalization raising concern for C. diff
- Not severely immunocompromised with worsening or prolonged symptoms
- Located in Missouri at time of visit
Red Flags Requiring In-Person or ER Care
- Bloody or black tarry stools
- Fever above 102°F with severe abdominal pain
- Unable to keep any fluids down for 12 or more hours with signs of dehydration
- Severe, localized abdominal pain, guarding, or rigid abdomen
- Signs of significant dehydration: dizziness on standing, no urine output for 8+ hours, confusion or extreme weakness
- Pregnancy with GI symptoms and systemic illness
- Severe immunosuppression with worsening symptoms
- Symptoms lasting more than 7 to 14 days without improvement
If any red-flag symptoms are present, seek urgent in-person or emergency care. TeleDirectMD is not an emergency service and is not appropriate for these situations.
Treatment Options
Viral gastroenteritis treatment is primarily supportive. The most important goal is maintaining hydration and preventing complications from fluid loss. Antibiotic therapy is not appropriate for viral gastroenteritis and is not prescribed. The ACG Clinical Guideline on acute diarrheal infections in adults recommends against empiric antibiotic therapy for community-acquired diarrhea when a viral origin is suspected, as most community-acquired diarrhea is caused by norovirus, rotavirus, or adenovirus and is not shortened by antibiotics.
Oral rehydration and hydration management
The cornerstone of viral gastroenteritis treatment is replacing lost fluids and electrolytes. Oral rehydration solutions (ORS) containing glucose and electrolytes are superior to sports drinks, juice, or plain water for addressing the fluid losses from diarrhea and vomiting. Adults can supplement with water, broths, and electrolyte drinks. The NIDDK recommends sipping small amounts frequently if vomiting is a problem, and gradually increasing intake as tolerated. Oral rehydration guidance and assessment of dehydration severity are a key part of the TeleDirectMD evaluation.
Anti-emetic therapy (prescription)
For adults with significant nausea and vomiting that interfere with oral rehydration, ondansetron (Zofran) is a commonly prescribed anti-emetic. Ondansetron helps reduce vomiting frequency, supports oral rehydration success, and can reduce the need for IV fluids or emergency care. When clinically appropriate, TeleDirectMD can prescribe ondansetron during the video visit. IDSA guidelines support the use of antiemetics to facilitate tolerance of oral rehydration in patients with acute gastroenteritis associated with vomiting.
Over-the-counter supportive options
Bismuth subsalicylate (Pepto-Bismol, Kaopectate) can reduce diarrhea frequency in adults with viral gastroenteritis when used appropriately. Loperamide (Imodium) may reduce stool frequency in some adults with non-bloody, afebrile viral diarrhea, but should be avoided if there is bloody diarrhea or fever, as these may suggest a bacterial cause. The NIDDK notes that OTC options for diarrhea should not be used when bloody diarrhea or fever is present. The MD will discuss whether these options are appropriate based on your specific history.
Diet and recovery guidance
Research does not support fasting or highly restricted diets for viral gastroenteritis. When appetite returns, patients can gradually resume a normal diet. Avoiding caffeine, high-fat foods, and dairy in the acute phase may reduce symptoms in some patients. The NIDDK and current guidelines do not recommend the traditional BRAT diet (bananas, rice, applesauce, toast) as an exclusive regimen, though these bland foods are generally well tolerated early in recovery.
What TeleDirectMD Does Not Manage
- Severe dehydration requiring IV fluid resuscitation — needs urgent care or ER
- Bloody diarrhea or suspected bacterial gastroenteritis, C. diff, or IBD flare requiring stool testing and targeted therapy
- Suspected appendicitis, bowel obstruction, or other acute abdominal surgical emergency
- Gastroenteritis in immunocompromised patients with rapidly worsening or prolonged symptoms requiring in-person evaluation
- Viral gastroenteritis in pregnancy with systemic symptoms requiring same-day in-person assessment
Common Medication Options
These are common examples of medications used for viral gastroenteritis symptom management in adults. The actual medication, dose, and whether it is appropriate is determined by the MD after reviewing your symptoms, severity, stool character, fever pattern, fluid intake, and medical history.
| Medication | Typical adult dose | Used for | Key considerations |
|---|---|---|---|
| Ondansetron (Zofran) — prescription | 4 mg by mouth every 6 to 8 hours as needed | Nausea and vomiting relief; supports oral rehydration | First-choice anti-emetic for viral gastroenteritis. Helps reduce vomiting to allow fluid intake. Avoid in patients with prolonged QT interval or relevant drug interactions. Not a controlled substance. |
| Bismuth subsalicylate (Pepto-Bismol, Kaopectate) — OTC | 30 mL (525 mg) every 30 to 60 minutes as needed, up to 8 doses per day | Reduces diarrhea frequency and nausea | Available over the counter. Avoid if allergic to aspirin or salicylates, if taking blood thinners, or if bloody diarrhea or fever is present. May cause temporary darkening of the stool or tongue. |
| Loperamide (Imodium) — OTC | 4 mg initial dose, then 2 mg after each loose stool, max 16 mg per day | Reduces stool frequency in afebrile adults with watery diarrhea | IDSA guidelines note loperamide may be given to immunocompetent adults with acute watery diarrhea but should be avoided when bloody diarrhea, high fever, or suspected inflammatory or bacterial cause is present. Not recommended in children under 18. |
| Oral rehydration solution (Pedialyte, Liquid IV, Normalyte) — OTC | As tolerated — sip frequently in small amounts if vomiting, 200 to 400 mL after each loose stool if tolerated | Fluid and electrolyte replacement to prevent or treat mild dehydration | Commercial ORS products containing glucose and electrolytes are superior to sports drinks for replacing GI losses. Recommended by the NIDDK for older adults and adults with severe diarrhea or dehydration symptoms. |
| Promethazine (Phenergan) — prescription, not routinely preferred | 12.5 to 25 mg every 4 to 6 hours as needed | Nausea and vomiting in adults when ondansetron is not suitable | Less preferred than ondansetron due to sedation and anticholinergic side effects. TeleDirectMD does not prescribe controlled substances; promethazine is not a controlled substance but is used selectively. |
Important: Example regimens only. The actual medication, dosing, and appropriateness are determined by the MD after reviewing your symptoms, stool character, fever, fluid status, drug interactions, and medical history. Antibiotics are not appropriate for viral gastroenteritis and are not prescribed. TeleDirectMD does not prescribe controlled substances.
Home Care, Recovery Timeline, and Follow-up
What to Do Now
- Prioritize hydration — sip oral rehydration solution, water, or broths in small frequent amounts; commercial ORS products (Pedialyte, Normalyte, Liquid IV) are better than sports drinks for replacing electrolytes lost from diarrhea
- Rest your gut — when vomiting is active, avoid solid foods; as nausea improves, gradually reintroduce bland, easily digested foods such as saltine crackers, toast, rice, and broth
- Avoid caffeine, alcohol, dairy, high-fat foods, and highly sugary drinks during the acute phase as these can worsen diarrhea and delay recovery
- Wash your hands frequently with soap and water — handwashing is more effective than hand sanitizer against norovirus
- Stay home and avoid food preparation for others while symptomatic and for at least 48 hours after symptoms resolve, to prevent spreading illness to close contacts
- Take anti-emetics as directed if prescribed — ondansetron helps reduce vomiting and makes it easier to stay hydrated at home
What to Watch For Over the Next 24 to 72 Hours
- Signs of significant dehydration at any time — dizziness when standing, no urination for 8 or more hours, extreme dry mouth, confusion, or fainting require urgent in-person care or ER
- Bloody or black tarry stools — not typical of viral gastroenteritis and require prompt in-person evaluation
- Fever rising above 102°F with worsening abdominal pain — may suggest bacterial gastroenteritis or another serious cause
- Inability to keep any fluids down for 12 or more hours despite anti-emetic therapy — needs urgent care or ER for IV fluids
- Severe or localized abdominal pain that is worsening rather than crampy and diffuse — may suggest appendicitis or other surgical cause
- Symptoms that are not improving after 3 to 5 days or that persist beyond 7 days — may warrant in-person evaluation for stool testing and reassessment
Follow-up Timing
- Most uncomplicated viral gastroenteritis resolves within 1 to 3 days — formal follow-up is often not needed if symptoms improve steadily
- If symptoms persist beyond 5 to 7 days, schedule a follow-up with primary care for stool studies and evaluation for bacterial or parasitic causes
- If symptoms recur frequently or you have recurring bouts of GI illness, evaluation by a primary care physician or gastroenterologist is recommended to rule out chronic GI conditions
- For individuals who are older, have immune system conditions, or take multiple medications, earlier follow-up with primary care is advised even for mild illness

Viral Gastroenteritis FAQs for Missouri
Can I get stomach flu treatment online in Missouri?
Yes, if you are an adult 18+ located in Missouri and your symptoms are consistent with uncomplicated viral gastroenteritis after red-flag screening. TeleDirectMD can prescribe anti-emetics like ondansetron when clinically appropriate, provide oral rehydration guidance, and give you clear follow-up instructions. Adults with bloody stool, severe dehydration, high fever with severe abdominal pain, or suspected surgical emergency are directed to in-person care.
How much does an online stomach flu visit cost in Missouri?
TeleDirectMD offers a transparent self pay option starting at $49 for an adult video visit in Missouri. Insurance is not required. Prescription costs at your pharmacy are separate and vary by medication and pharmacy.
Does Missouri allow telemedicine for this kind of visit?
Yes. Missouri allows licensed professionals to provide telemedicine within their scope when appropriate and according to accepted standards of care.
Can TeleDirectMD prescribe Zofran (ondansetron) for nausea and vomiting from the stomach flu?
Yes, when clinically appropriate. Ondansetron (Zofran) is a commonly used anti-emetic for viral gastroenteritis in adults. It helps reduce vomiting frequency and supports oral rehydration. The MD will review your symptoms, fever, stool character, fluid status, and medical history to determine whether it is safe and appropriate for you. TeleDirectMD does not prescribe controlled substances.
What is the difference between viral gastroenteritis and food poisoning?
Viral gastroenteritis is caused by viruses like norovirus and typically causes watery (non-bloody) diarrhea, nausea, vomiting, and low-grade fever lasting 1 to 3 days. Food poisoning from bacterial toxins (such as Staphylococcus aureus or Bacillus cereus) often has a rapid onset within hours of eating contaminated food and may cause more prominent vomiting early. In practice, both are managed similarly with supportive care. Bloody diarrhea, high fever, or prolonged illness more often suggests a bacterial cause requiring in-person evaluation.
When should I go to the ER for stomach flu?
Go to the ER if you have severe dehydration (dizziness or fainting when standing, no urine output for 8 or more hours, confusion or extreme weakness), bloody or black tarry stools, high fever above 102°F with severe abdominal pain, inability to keep any fluids down for 12 or more hours, severe and localized abdominal pain that may suggest appendicitis, or any signs of rapid deterioration. TeleDirectMD is not an emergency service.
Should I take antibiotics for the stomach flu?
No. Antibiotics do not work against viruses and are not prescribed for viral gastroenteritis. The ACG Clinical Guideline on acute diarrheal infections states that antibiotics are not recommended for community-acquired diarrhea when a viral origin is likely. Taking antibiotics inappropriately can cause side effects and antibiotic resistance. If your illness suggests a bacterial cause — such as bloody diarrhea, high fever, or prolonged symptoms — in-person evaluation and stool testing may be needed to determine whether antibiotics are appropriate.
What should I eat or drink when I have the stomach flu?
Focus on hydration first. Sip oral rehydration solutions, water, or broths frequently in small amounts if you are vomiting. Commercial ORS products like Pedialyte or Normalyte are better than sports drinks for replacing electrolytes. When you can tolerate solids, bland foods like crackers, toast, rice, and broth are a good starting point. Avoid caffeine, alcohol, dairy, and high-fat foods in the acute phase. The NIDDK notes that most people can return to their normal diet when appetite returns, even if diarrhea persists.
Is loperamide (Imodium) safe to take for the stomach flu?
Loperamide can reduce stool frequency in some adults with watery, non-bloody, non-febrile viral gastroenteritis. However, IDSA guidelines state it should be avoided if bloody diarrhea or fever is present, as these may indicate a bacterial infection where slowing gut motility could be harmful. Your TeleDirectMD physician will review whether loperamide is appropriate for your specific situation.
How long does viral gastroenteritis last?
Most cases of viral gastroenteritis caused by norovirus resolve within 1 to 3 days. Some cases can last up to a week. Symptoms lasting more than 7 to 10 days should prompt reassessment for bacterial, parasitic, or other causes. StatPearls notes that illness lasting more than 2 weeks is classified as chronic and does not meet criteria for acute gastroenteritis.
Can TeleDirectMD provide stomach flu care in other states?
Yes. TeleDirectMD offers adult evaluations via video visits across multiple states where our physicians are licensed. You must be physically located in the state where you are requesting care at the time of the video visit.
Can TeleDirectMD treat children with the stomach flu?
No. TeleDirectMD treats adults 18+ only. Children with vomiting, diarrhea, or stomach flu symptoms should be evaluated by a pediatrician or pediatric urgent care provider.
Can I use my insurance for a TeleDirectMD visit?
Insurance is not required. A self pay option is available starting at $49. If your plan is eligible, you may be able to use insurance.
How do I prevent spreading the stomach flu to others in my household?
Wash your hands frequently with soap and water — handwashing is more effective than alcohol-based hand sanitizer against norovirus. The CDC recommends staying home and avoiding food preparation for others while sick and for at least 48 hours after symptoms resolve. Clean and disinfect contaminated surfaces with a bleach-based solution. Avoid sharing utensils, towels, or cups.
