Question:

I started having a fever on January 1st and was diagnosed with Influenza A on January 2nd. By the evening of January 3rd, my fever had completely subsided. Currently, I only have mild throat discomfort and an occasional cough. My 4-year-old child at home has no symptoms yet. Fortunately, I started wearing a mask even before January 1st when my throat first felt scratchy. Can I still transmit the flu to my child? Should I keep my mask on?


Answer:

You must be very worried about preventing the spread of the flu within your family. You have done a fantastic job being cautious and wearing a mask early on.


Contagious Period

  • The flu is generally contagious from 1 day before symptoms start until 5 to 7 days after the onset of symptoms.

  • Even after your fever drops, you are still contagious for another 24 to 48 hours.

  • Since your fever subsided on the evening of January 3rd, you need to remain careful until at least January 5th.


How to Protect Your Child

  1. Masks: It is recommended that you continue wearing a mask until January 6th, especially when you are in close contact with your child.

  2. Hand Hygiene: Wash your hands frequently (10+ times a day), particularly before touching your child.

  3. Household Items: Use separate eating utensils, cups, and towels.

  4. Ventilation: Air out your home for about 10 minutes every 2 hours.

  5. Isolation: If possible, use a separate bedroom from your child.


What to Watch For

  • The incubation period for Influenza A is typically 1 to 4 days, so pay close attention to your child's condition until January 6th.

  • If your child develops a fever of 38°C (100.4°F) or higher, a headache, or muscle aches, please visit a pediatrician immediately for an evaluation.

  • You may also consult your doctor about whether preventive antiviral medication (like Tamiflu) is appropriate for your child.


You have managed everything very well so far, so hang in there just a little longer! It should be safe for you to take off your mask after January 6th.
