In Ho Chi Minh City, in October 2025, the number of outpatient visits at Children's Hospital 2 nearly doubled - from more than 6,000 to more than 12,000 children in just one week. The number of hospitalizations due to respiratory diseases also increased sharply, from 286 to 475 cases.
When children are sick, they have to stay home from school, and parents have to temporarily put aside work to take care of them, disrupting family life. Therefore, proactively strengthening children's immunity and resistance is the "key" to helping children stay healthy and cope with unpredictable weather.

Just one time the child gets sick, the whole family's life is turned upside down.
Changing seasons – a "big challenge" for children's immune systems
Children aged 2-12 years old have an incomplete immune system so they are susceptible to the following diseases:
- Flu, cold: Due to viruses spreading rapidly when the weather changes. Children often have fever, cough, stuffy nose, sore throat, fatigue, especially contagious if someone in the house has the flu.
- Respiratory diseases: Sore throat, tonsillitis, bronchitis, pneumonia... appear when viruses and bacteria attack the child's weak respiratory system.
- Other infectious diseases: Measles, chickenpox, dengue fever, hand, foot and mouth disease, otitis media... also increase during the changing seasons.
Parents always try to take care of their children by supplementing milk, nutritious foods or vitamins, but natural nutrition is not always enough - especially for children with poor appetite or poor absorption. According to experts, there are some cases where only supplementing through food is not enough due to the quality of meals and eating habits of each child, especially children with poor appetite will receive less nutrients than other children.
To help children stay healthy, parents should combine many measures at the same time:
- Get enough sleep : Helps the body restore energy and increase immunity.
- Balanced nutrition : Increase green vegetables and fruits rich in vitamins C, A, E (oranges, tangerines, carrots...), along with enough protein from meat, fish, eggs, and milk to create antibodies.
- Outdoor exercise : Sunbathing in the morning and playing light sports helps the body absorb natural vitamin D and increase respiration.
- Keep warm properly : Wear many thin layers of clothing for easy adjustment, pay attention to keep your neck, chest and feet warm.
- Clean your nose, throat and hands regularly: Wash your hands with soap and clean your nose and throat with saline to prevent viruses and bacteria from entering.
According to experts, children's weak immunity is largely due to a lack of micronutrients such as Vitamin C, D, Zinc, Selenium, Lactoferrin and Beta-glucan - substances that increase immune cell activity.
Selenium is known as the "golden micronutrient" of the immune system. This is a trace element that helps create Selenoproteins - a special group of proteins that play a role in neutralizing free radicals, enhancing immune cell activity and reducing inflammation. Selenium is also especially important for lung and respiratory health - the organs most vulnerable to weather changes.
However, the body cannot synthesize Selenium itself, so children need to supplement it through food or support products such as granules and syrups. Selenium deficiency makes children susceptible to infections, especially respiratory diseases, and slows down the recovery process after illness.
