The flu virus is most contagious during the first 3 to 4 days of illness. If your child has the flu, you should wait until he or she has fully recovered before getting the flu vaccine.
Dr. Tran Hang Ni, 315 Clinic System (HCMC) said that in our country, flu circulates all year round, but tends to be concentrated in winter and spring. The peak of flu usually falls from December to April every year.
If your child has the flu, you should wait until he or she is completely recovered before getting the flu vaccine. Getting the flu vaccine after the illness has passed will help protect your child from other strains of the flu virus in the future.

Two main routes of transmission of influenza
Specialist Doctor 1 Cao Thi Lan Huong, Clinic System 315 (HCMC) said that flu has two main routes of infection.
Through the respiratory tract : The most common way of transmission is through the respiratory tract. When an infected person coughs, sneezes or talks, droplets containing the virus are released into the air. These droplets can be inhaled by others at close range, especially in enclosed or crowded spaces. According to medical studies, droplets containing the virus can often remain suspended in the air and survive long enough to infect others within a few meters.
Through contact : In addition, influenza is also spread through contact. This happens when a person touches a surface or object that has been contaminated with the virus and then touches his or her face, nose or mouth. Surfaces such as doorknobs, keyboards or telephones can easily become temporary homes for the virus if not cleaned regularly. Proper hand washing with soap and water or using hand sanitizer is recommended as an effective measure to reduce the risk of infection through contact.
Wearing a mask when going to crowded places is one of the effective ways to prevent flu.
Flu is most contagious during the first 3-4 days.
According to Dr. Cao Thi Lan Huong, people with the flu are usually no longer contagious to others within 5 to 7 days, and the ability to spread the disease usually decreases from the 4th day.
Influenza patients are often able to infect others from 1 day before the appearance of flu symptoms such as fever, cough, headache, stuffy nose, runny nose, etc.
In some cases, such as children, immunocompromised people, and people with severe flu, the flu virus can be transmitted for a longer period of time, until all symptoms subside.
The flu is most contagious during the first 3-4 days of illness. This is when a person is most susceptible to catching the flu. This is when the sick person coughs and sneezes a lot, causing the virus to be sprayed into the air and onto surrounding objects.
