Answer:

Many individuals share the folk remedy of placing onion slices on a child's feet to reduce fever, treat coughs, or clear stuffy noses. However, there is no scientific evidence to support the claim that onions absorbed through the skin have these effects, so this method should not be used.

Influenza A typically causes high fevers, between 39-40 degrees Celsius, along with coughs, sore throats, runny noses, body aches, and nausea. For young children, inadequate care can lead to serious complications such as: pneumonia, otitis media, meningitis, and respiratory failure. Parents must adhere to a doctor's instructions: administer fever-reducing medication at the correct dosage, sponge bathe with warm water, dress the child in light, breathable clothing, provide sufficient fluids and nutrition, and monitor for severe symptoms to ensure timely hospitalization.

Influenza A is an infectious disease readily transmitted via the respiratory tract, frequently affecting young children due to their weaker immune systems. Cold weather provides an environment for the virus to multiply and spread. To prevent the illness, children require balanced nutrition, frequent handwashing, mask-wearing in crowded areas, and avoidance of contact with sick individuals.

Flu vaccination is a highly effective preventive measure. Vietnam currently offers four types of flu vaccines from France, Netherlands, South Korea, and Vietnam, suitable for individuals from 6 months of age to adults. Children under 9 years old who have not been previously vaccinated need two doses administered one month apart. Individuals aged 9 and above, as well as adults, require only one dose, with annual boosters recommended by the World Health Organization (WHO). Pregnant women can receive the flu vaccine at any stage, ideally from the second trimester, to transfer protective antibodies to the infant during the first six months of life.
