Not only has the rainy season begun, but the Habagat is also making its presence felt more frequently. With these changing weather patterns, parents are braving themselves for their children to get sick more often.

“Viruses like rhinovirus, influenza, and RSV tend to spread more easily during the rainy months,” explains pediatric pulmonologist Dr. Jade Rojas-Neri, who is also a mom to a seven-month-old baby. “These viruses survive longer in cool, humid weather and spread faster under such conditions.”

We also tend to keep windows shut to keep the rain out, which limits fresh airflow, especially in crowded spaces like schools and daycare centers. Unfortunately, this creates an ideal breeding ground for germs to linger and spread more easily among children.

Knowing when your child is coming down with something can help you act fast. Dr. Jade shares that symptoms usually appear about five to seven days after exposure. “Early signs include a scratchy throat, sneezing, and a runny nose that starts clear but thickens. A dry cough may develop and later become wet. Some children may have a low-grade fever or seem more tired than usual. Babies can get fussier and eat less.”

While these reminders are essential year-round, the rainy season calls for extra vigilance. Dr. Jade advises practicing good hygiene such as frequent handwashing with soap or using alcohol-based sanitizers when outdoors.

Remind children to avoid touching their faces as germs can enter through the eyes, nose, and mouth. Disinfect high-touch surfaces regularly, and this includes doorknobs, switches, and gadgets. Steer clear of close contact with sick people, especially in enclosed spaces.

To help children build stronger resistance during this rainy season, Dr. Jade emphasizes that it’s the small, consistent habits that can make a difference.

Hydrate. “Water helps keep the nose and throat moist,” she explains. “That moisture traps germs and makes it harder for viruses to get through.” If you’re unsure how much your child should be drinking, it’s always best to check with your pediatrician.

Prioritize sleep. Kids who get enough rest don’t just grow better—they’re also more resilient. “Sleep allows the body to recharge and fight off infections more effectively,” she says. Lack of sleep weakens immunity, especially in young children.

Eat smart. A healthy plate fuels the body with essential vitamins and minerals. These nutrients are what build strong immune cells, repair tissues, and give children the energy they need to recover faster or stay well.

Encourage playtime. “Regular physical activity helps improve blood circulation and lung function,” she says. It also activates the immune system, making it more efficient at protecting the body.

Take shots. Dr. Jade reminds parents that vaccines, especially the flu shot and pneumococcal vaccine, offer extra protection during this rainy season when respiratory illnesses peak.

Once a cold or cough sets in, parents can take practical steps to ease discomfort and speed healing by keeping them at home to rest. “No mall, no parties, no funerals. Let them rest at home to recover, avoid spreading germs, and importantly, also prevent catching more infections while their immune system is down.” Their room should have good ventilation with moderate temperature. Keep noise level low.

It’s also important to give medicine only when needed, and always under the guidance of your pediatrician. “No antibiotics unless prescribed,” she cautions. “Most coughs and colds are viral and don’t require them. Giving antibiotics unnecessarily can sometimes slow down recovery instead of helping.”

Dr. Jade suggests this simple head-to-toe check to know when it’s time to seek medical help. Start with the head. Is your child unusually sleepy, drowsy, or difficult to wake? Look at the nose. Are the nostrils flaring when they breathe? Check the mouth. Do the lips look pale, dry, or bluish? Watch the chest. Are they breathing fast, struggling to breathe, wheezing, or do you notice the chest pulling in with each breath (a sign called retractions)?

Moving down to the abdomen, observe if your child is vomiting frequently or refusing to eat. Finally, check the legs and toes. Do they seem unusually weak, not want to walk, or only want to be carried all the time?

And if a fever is high and lasts for more than three days or a cough lasting more than two weeks, then it is best to consult with your pediatrician.
