World Malaria Day 2025: Why children under 5 years of age are at risk of vector borne disease: What parents should know (image credit: ISTOCK)
Malaria continues a major global health risk, especially in tropical and subtypes. The most susceptible population, children of less than five years, the most deadly malaria is the risk of disease and mortality. This sensitivity is based on organic, immunological and physical explanation, not by coincidence. Malaria may be a stopping disease, but it continues to take heavy toll on children. Despite progress in treatment and awareness, this age group is the weakest. But why are these small people at such a high risk?
“North lies in his biology,” Dr. Dr., Senior Advisor and In -Charge of Pediatrics Intensive Care Unit (PICU) at Margego Asia Hospital in Gurugram. Rashmi Bhardwaj says. He said, “There is an immature immune system in children under five years of age, which have not got a chance to make any kind of defense against malaria.”
Life-threatening complexity
Lack of immunity means that when malaria attacks, it hits hard. Unlike older people, where symptoms may come out more slowly, the disease can progress with dangerous speed in young children.
“Malaria in a child or baby may increase in complications such as cerebral malaria – where the brain is affected – or severe anemia due to the destruction of red blood cells.” “These can be a threat to life immediately if not treated immediately.”
Dehydration
Another major concern is that small children have low fluid reserves. With symptoms such as high fever, sweating, vomiting and diarrhea, dehydration can be set quickly – and dangerously.
“Dehydration is not just a side-effect; it is a serious complexity in itself,” Dr. Bhardwaj says. “In children under five, even in mild dehydration, their condition may deteriorate rapidly. That is why timely intervention is important.”
High parasitic burden means rapid decline
To make cases worse, young children carry a high parasitic burden – meaning that there are more malaria parasites in their bloodstream than adults or older children that may have some immune.
“Pediatrics in my experience in ICU, we often see that things have already increased by the time parents bring them to their baby. Fever can begin a day before, but in a child under five, 24 hours can bring a big difference,” Dr. Bhardavaj warned.
Prevention is possible
The good news is that malaria is highly prevented. Parents can take simple, effective steps to protect their children.
“Make sure that your child sleeps under a pesticide-undesken bed net every night. Avoid playing outdoor from evening to evening when mosquitoes are most active. Dress them in long sleeves and pants, and use replants of mosquito approved mosquito.
Be cautious
Finally, awareness and quick action are important. “Any fever in a child under five, especially in malaria-affected areas, should be taken seriously. Do not wait. Early pay medical attention.”
