The return to school during the monsoon often leads to a rise in childhood infections. Dr Nehal Shah explains the 'school reopening effect', common seasonal illnesses, and practical tips parents and schools can follow to keep children healthy during the rainy season.

As Dr Nehal Shah, Consultant in Paediatric Medicine at Narayana Health SRCC Children's Hospital, says, this is commonly known as the "school reopening effect", where humid weather conditions and crowded classrooms lead to the rapid spread of infections among children.

Why the 'school reopening effect' happens

Dr Shah explains that children spend their summer holidays largely within the safety of their homes. Once schools reopen, they suddenly begin interacting closely with dozens of classmates. "They share classrooms, benches, books, stationery and sports equipment. This close contact allows viruses and bacteria to spread rapidly through respiratory droplets and contaminated surfaces," says Dr Shah.

The monsoon season makes the situation even more challenging. High humidity allows some viruses to survive longer on surfaces, while moisture in the air keeps droplets released through coughing or sneezing suspended for longer. Stagnant rainwater around schools also creates breeding grounds for mosquitoes that spread diseases.

Common illnesses during the monsoon

According to Dr Shah, several illnesses become more common after schools reopen. Respiratory infections such as the common cold, cough, viral fever and bronchitis spread easily among children sharing enclosed classrooms.

Gastrointestinal infections are another concern. Contaminated food or drinking water can increase the risk of diarrhoea, rotavirus infections and bacterial stomach illnesses.

What increases the risk?

Dr Shah says multiple factors contribute to this seasonal rise in infections. During the holidays, children's immune systems are exposed to fewer germs. Once school resumes, they suddenly encounter a wide range of viruses and bacteria, making them more vulnerable to falling ill.

Poor hygiene can further increase transmission. "Proper handwashing should include cleaning the wrists, between the fingers and under the fingernails," advises Dr Shah.

He also points out that disrupted sleep schedules, unhealthy holiday eating habits and inadequate nutrition can weaken a child's natural immunity, making it harder to fight infections.

How parents can keep children healthy

Dr Shah recommends that parents focus on prevention rather than treatment. Teach children to wash their hands thoroughly with soap for at least 20 seconds, especially after using the toilet, before meals and after returning home from school.

They should also learn proper respiratory etiquette by covering their mouth and nose with a tissue or their elbow while coughing or sneezing. "If your child is unwell, keep them at home. Sending a sick child to school only increases the spread of infections among classmates and teachers," he says.

Schools also play an important role

According to Dr Shah, schools share equal responsibility in preventing outbreaks. Regular cleaning of classrooms, desks, door handles, washrooms and drinking water facilities can significantly reduce the spread of germs.

Awareness sessions in schools can also help children understand the importance of maintaining good hygiene during the monsoon.

Building immunity through good health practices

As recommended by Dr Shah, parents should provide their children with a diet that includes plenty of vegetables, seasonal fruits and other nutrient-rich foods. Adequate intake of clean drinking water should also be maintained.

Adequate sleep is important as it allows the body to recover and strengthen its immune system.

It is also important for parents to ensure that all their child's vaccinations are up to date.

Do not ignore the warning signs

While most seasonal infections are usually mild, Dr Shah suggests consulting a doctor if a child develops a persistent fever, breathing difficulties or severe stomach pain.

"Do not wait for symptoms to worsen. Early medical advice can help children recover faster and prevent complications," he says.

The increase in infections after schools reopen during the monsoon is a predictable seasonal pattern, but it is also one that can be managed.
