Does a 9-year-old child need a follow-up appointment after recovering from the flu?


Hello, my child is in the third grade and has been diagnosed with influenza A.
They have been taking antiviral medication for five days and their fever has subsided, but they are experiencing extreme fatigue.
Before getting sick, their appetite was very good, but since the fever, they have had a poor appetite.
Should we schedule a follow-up appointment with the doctor?

After recovering from the flu and even if you have taken antiviral medication like Tamiflu, you should return for a follow-up evaluation if you experience any discomfort, to prevent complications or sequelae.
Thank you.

When it comes to managing a child's health after a diagnosis of influenza, particularly in the case of your 9-year-old who has been treated with antiviral medication for five days, there are several important considerations to keep in mind.

Firstly, it is encouraging to hear that your child has experienced a reduction in fever, which is a positive sign in the recovery process. However, the persistent fatigue and loss of appetite you mentioned are common symptoms that can linger even after the acute phase of the illness has resolved. Influenza can take a toll on the body, and it is not unusual for children to feel fatigued and have a decreased appetite for some time after the fever has subsided. This is often referred to as post-viral fatigue, and it can last for several days to weeks.

Despite these common post-influenza symptoms, it is essential to monitor your child's overall condition closely. Here are some key points to consider regarding whether a follow-up visit is necessary:
1. Duration of Symptoms: If your child's fatigue and loss of appetite persist beyond a week or if they worsen, it would be prudent to schedule a follow-up appointment. Prolonged symptoms could indicate a secondary infection or other complications that may require medical attention.

2. Hydration and Nutrition: Ensure that your child stays well-hydrated and tries to eat small, nutritious meals even if their appetite is low. Sometimes, offering favorite foods or small snacks can help stimulate appetite. If they are unable to keep fluids down or show signs of dehydration (such as dry mouth, decreased urination, or lethargy), a visit to the doctor is warranted.

3. Other Symptoms: Keep an eye out for any new or concerning symptoms, such as difficulty breathing, chest pain, persistent cough, or any signs of dehydration. If any of these occur, seek medical attention immediately.

4. Follow-Up Care: If your child was prescribed antiviral medication, it is important to complete the course as directed. If there are any concerns about the effectiveness of the treatment or if symptoms do not improve, a follow-up visit can provide reassurance and allow the physician to assess whether further intervention is needed.

5. Emotional Well-Being: Sometimes, children may experience emotional or psychological effects after being ill, which can also contribute to fatigue and changes in appetite. If you notice any signs of anxiety or depression, discussing these with a healthcare provider can be beneficial.

In summary, while it is common for children to feel fatigued and have a reduced appetite after recovering from influenza, it is essential to monitor their symptoms closely. If the fatigue and loss of appetite persist beyond a week, worsen, or are accompanied by other concerning symptoms, a follow-up appointment with your child's healthcare provider is advisable. They can conduct a thorough evaluation to ensure that your child is recovering appropriately and rule out any potential complications. Always trust your instincts as a parent; if you feel something is off, it is better to err on the side of caution and seek medical advice.

Should My Kids Get the New Flu Vaccine After Having Influenza?

My children are in the second and third grades of elementary school. In September of this year, they had a fever and tested positive for influenza A through a rapid test. Should they receive the new influenza vaccine?


Dr. Xiao Kaiwen reply Pediatrics
A rapid test that indicates influenza A does not necessarily mean it is H1N1 (as H1N1 is just one subtype of influenza A). It could also be an infection from other strains of influenza A, so vaccination against the new influenza (H1N1) vaccine is still recommended.
