Prevention Strategies

🧼

Good Hygiene

Teach proper handwashing, cover coughs and sneezes, avoid touching face, and clean frequently touched surfaces.

💉

Vaccinations

Keep up with recommended vaccines including flu shots, COVID-19 vaccines, and other age-appropriate immunizations.

🏠

Stay Home When Sick

Keep children home when they're sick to prevent spreading illness to others. Follow school and daycare policies.

Testing and Diagnosis

What Doctors May Do

  • • Flu: a swab test can check for influenza virus.
  • • COVID-19: rapid antigen or PCR testing of nasal/respiratory sample.
  • • RSV: exam usually enough; sometimes a nasal swab is done.
  • • Cold: no test; supportive care while it runs its course.

When Testing Helps

  • • To guide treatment (e.g., antivirals for flu, isolation for COVID-19).
  • • If your child is high-risk or very unwell.
  • • If symptoms could be more than one infection or overlap significantly.

Home Care and Treatment

Comfort Measures

  • • Rest, fluids, humidifier, saline nose drops.
  • • Fever reducers as advised by your doctor.
  • • Honey for cough in kids over 1 year (never under 1).

Medicines

  • • Antibiotics do not treat viruses (cold, flu, RSV, COVID-19).
  • • Antivirals may be used for flu; select kids at risk for severe COVID-19 may get antivirals.
  • • Avoid OTC cough/cold meds in young children unless your doctor advises.

Hydration & Nutrition

  • • Offer small, frequent sips; aim to prevent dehydration.
  • • Cool liquids may soothe sore throats; avoid irritants.
  • • Monitor wet diapers/urine output as a hydration check.

Contagiousness and Return to School

General Guidance

  • • Keep kids home if they have fever, significant cough, or feel unwell.
  • • Return when fever-free for 24 hours without fever meds and symptoms are improving.
  • • Follow current school/daycare and local health guidance for COVID-19 isolation.

Reduce Spread

  • • Handwashing, covering coughs/sneezes, cleaning high-touch surfaces.
  • • Consider masks during active illness per local recommendations.

Frequently Asked Questions

How can I tell if my child has COVID-19 or just a cold?

COVID-19 symptoms can overlap with cold symptoms, making it difficult to distinguish without testing. If your child has respiratory symptoms, especially if they've been exposed to someone with COVID-19, consider getting them tested. The only way to know for sure is through a COVID-19 test. When in doubt, consult your pediatrician.

Should I give my child antibiotics for a cold or flu?

No, antibiotics don't work against viruses like colds, flu, RSV, or COVID-19. Antibiotics only work against bacterial infections. Giving antibiotics unnecessarily can lead to antibiotic resistance and side effects. Most respiratory illnesses in children are viral and will resolve on their own with supportive care. Only use antibiotics if prescribed by your doctor for a bacterial infection.

When should I get my child tested for COVID-19?

Get your child tested for COVID-19 if they have symptoms, have been exposed to someone with COVID-19, or if required by school/daycare policies. Testing is especially important if your child has been in close contact with someone who tested positive or if they're planning to travel or attend events. Follow your local health department guidelines for testing recommendations.
