Post-Influenza Care: When to See a Doctor After Type B Flu - Family Medicine

Post-treatment for Influenza B


Hello doctor, my wife tested positive for influenza B with a rapid test.
After taking medication, her fever has subsided, but now she is experiencing throat discomfort and persistent coughing.
I would like to ask which specialty we should see after finishing the current medication.
Should we just see a general practitioner for a common cold? Initially, we went to the emergency room because her fever wouldn't go down.

Hello, Akai user: If your symptoms do not improve after taking the medication, you may visit a family medicine physician for further evaluation to check for any other changes.

More Info


After recovering from Type B influenza, it is common for patients to experience lingering symptoms such as a sore throat and persistent cough. These symptoms can be due to several factors, including post-viral cough, secondary bacterial infections, or even irritation from the initial viral infection.
In your wife's case, since she has already tested positive for Type B influenza and has been treated with antiviral medication, it is important to monitor her symptoms closely. If her cough and throat discomfort persist after completing her medication, it would be advisable to consult a healthcare provider.
1. When to See a Doctor: If your wife experiences any of the following symptoms, it would be wise to seek medical attention:
- Difficulty breathing or shortness of breath
- Chest pain or pressure
- High fever returning after initial improvement
- Coughing up blood or mucus that is yellow or green
- Severe sore throat that does not improve with over-the-counter medications
2. Which Specialist to See: If her symptoms are primarily related to her throat and cough, starting with a visit to a primary care physician or an ear, nose, and throat (ENT) specialist would be appropriate. They can evaluate her throat for signs of infection or other complications. If the cough is severe or persistent, a pulmonologist may also be consulted to rule out any underlying respiratory issues.

3. General Care: In the meantime, there are several self-care measures that can help alleviate her symptoms:
- Staying hydrated by drinking plenty of fluids
- Using throat lozenges or sprays to soothe throat discomfort
- Using a humidifier to keep the air moist, which can help ease coughing
- Over-the-counter cough suppressants or expectorants may also provide relief, but it’s best to consult with a healthcare provider before starting any new medication.

4. Monitoring Symptoms: Keep a close eye on her symptoms. If she develops new symptoms or if her current symptoms worsen, it would be prudent to seek medical advice sooner rather than later.

5. Follow-Up Care: After recovering from influenza, some patients may experience a post-viral cough that can last for weeks. This is usually self-limiting, but if it persists beyond a few weeks or is accompanied by other concerning symptoms, further evaluation may be necessary.

In summary, while it is common to have lingering symptoms after influenza, it is important to monitor her condition closely. If her symptoms do not improve or worsen, seeking medical attention is the best course of action. Starting with a primary care physician or an ENT specialist would be appropriate based on her symptoms.
