Question:

I am a mother of a 4-month-old baby. I initially thought I had a cold, and I took my baby to the pediatrician yesterday for cold symptoms. Because my baby is so young, they didn't perform a flu test and only prescribed standard cold medicine and fever reducers. However, I was just diagnosed with the flu today. Should I take my baby back to the pediatrician to get a flu test? Will the prescribed medication change if it is the flu?

Answer:

I completely understand your concern about your 4-month-old baby being exposed to the flu.

Since you have been confirmed to have the flu, your baby is at a high risk of exposure. Infants who are 4 months old fall into a high-risk category for influenza complications, so a prompt and proactive response is very important.

I strongly recommend visiting the pediatrician again today. When you go, be sure to inform the doctor about your confirmed flu diagnosis. The doctor will use this information to determine if a flu test is necessary for your baby.

Will the medication change?

Yes, the treatment plan may change. If your baby is diagnosed with or highly suspected of having the flu, the doctor can prescribe an antiviral medication (such as Tamiflu). Antiviral medications are most effective when started within 48 hours of symptom onset, and they are safe to be prescribed to a 4-month-old infant.

Please monitor your baby closely at home. Go to the emergency room immediately if your baby shows any of the following signs:

• A fever of 38°C (100.4°F) or higher

• Difficulty breathing, fast breathing, or chest retractions (the skin sinking in around the ribs/chest)

• A significant decrease in feeding (less than half of their normal amount) or no wet diaper for more than 8 hours

• Severe lethargy, lack of energy, or unresponsiveness

The flu can be dangerous for young infants, so please seek a prompt in-person medical evaluation to ensure your baby receives the appropriate care and treatment.
