How do you manage the flu and take flu vaccines at 27?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 27 and came down with a high fever, chills, sore throat, and body aches yesterday. I am worried it might be the flu. I have not taken the flu shot this year. Does that mean it will hit me harder? How do I know when I need to see a doctor or if it is just something I can rest off at home? Also, can I spread it even after I feel better?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern.

The protection that each flu vaccine gives does not last for a very long time, and the Influenza strains change every year; that is why we have to be vaccinated with it every year for continuous protection against the virus. Your previous vaccine may still give you a little protection, but probably not enough to cover the new strains, hence you may experience the present symptoms a little longer than if you had had the vaccine. Influenza viruses are usually self-limiting, which means they go away on their own. Therefore, you just need supportive management for symptomatic relief, such as Acetaminophen for the fever and body aches, warm saline gargle for the sore throat, and a tepid sponge bath to help lower your body temperature.

While you still have these symptoms, it is best to use protective measures such as using face masks and proper hand hygiene to avoid spreading the virus to others. If your symptoms last more than a week, it is best to see your primary care physician immediately for further evaluation and management.

The probable causes: Influenza virus.

Differential diagnosis: Bacterial Infection.

Probable diagnosis: Acute viral respiratory tract infection.

Treatment plan:

  1. Acetaminophen 500 mg, one tablet every four hours as needed for fever and body pain.

  2. Warm saline gargle, three to four times a day.

  3. Tepid sponge bath.

Regarding follow-up: May come back if with problems or other health concerns.

Preventive measures:

  1. Wear a face mask.

  2. Proper hand hygiene.

I hope this helps.

Kindly follow up if you have more concerns.

Thank you.
