For most people, a rain alert simply means carrying an umbrella or preparing for traffic jams. But for paediatricians, it often signals something else: a likely increase in children arriving at hospitals with infections, breathing problems and injuries. As the monsoon sets in across many parts of India, experts say weather forecasts may offer valuable clues about the kinds of health issues hospitals and parents should prepare for.
According to Dr Amin Kaba, Consultant, Paediatric Medicine, Narayana Health SRCC Children's Hospital, Mumbai, the link between heavy rainfall and childhood illnesses is well recognised in paediatric practice. Every monsoon, hospitals witness a familiar pattern where spells of heavy rain are followed by a rise in infections and emergency visits among children. He believes that rainfall alerts could eventually become an important tool for healthcare preparedness.
Why do children's illnesses increase after heavy rain?
Many parents believe that children falling ill during the rainy season happens at random. However, Dr Kaba says that doctors usually observe a pattern in which illnesses begin to appear just a few days after heavy rainfall.
Children spend more time indoors during the monsoon and are exposed to damp conditions. Once they go outside, they may come into contact with stagnant water, contaminated surfaces and disease-carrying mosquitoes. Moreover, waterlogging creates ideal conditions for the growth of infection-causing bacteria and insects.
According to Dr Kaba, this predictable pattern helps hospitals prepare for an increase in illnesses after heavy rainfall.
Common illnesses doctors see after rainfall
Within days of heavy rainfall, paediatric emergency departments commonly report an increase in:
- Viral fevers
- Respiratory infections
- Asthma flare-ups
- Allergic and inflammatory reactions
- Gastrointestinal infections
- Skin infections and rashes
- Hepatitis A
- Typhoid
- Leptospirosis
- Gastroenteritis
- Mosquito-borne diseases such as malaria, dengue, chikungunya and Japanese encephalitis
Dr Kaba says these illnesses often follow similar seasonal trends every year during the monsoon.
The hidden monsoon danger isn't always an infection
Rainy weather also increases the risk of accidental injuries among children.
Wet staircases, slippery playgrounds, damp school corridors and waterlogged roads can all contribute to falls and accidents. Every monsoon, paediatric emergency departments treat children with fractures, sprains, cuts and head injuries caused by slippery conditions.
According to Dr Kaba, familiar surroundings can quickly become hazardous after continuous rainfall.
Why asthma often worsens during the monsoon
Not every child visiting the hospital during the rainy season has an infection.
Dr Kaba explains that damp weather encourages the growth of mould and fungi, while changing humidity levels and airborne allergens released during rainfall can trigger asthma attacks and breathing difficulties in children with pre-existing respiratory conditions or allergies.
These environmental conditions make it more difficult for children with asthma to cope during the monsoon.
Can weather forecasts help hospitals prepare?
Healthcare professionals have started exploring how weather data can be used to improve emergency preparedness.
According to Dr Kaba, rainfall forecasts and environmental factors can help hospitals anticipate the types of cases that are likely to increase following heavy rain.
Rain alerts may become health alerts too
For children, the monsoon is often associated with puddle jumping, rainy-day snacks and outdoor fun. However, it is also a season that places extra pressure on their developing immune systems.
As climate patterns become increasingly unpredictable and urban populations continue to grow, Dr Kaba believes the link between climate and children's health will become even more significant. The next time you receive a rain alert on your phone, it may be worth thinking beyond the weather and considering what it could mean for your child's health.
