Thiruvananthapuram: Kerala is facing an increasing public health challenge as several infectious diseases continue to spread across the state during the monsoon season, raising concerns among health authorities and the public. Alongside a steady rise in fever cases, diseases such as Shigella infection, viral encephalitis, dengue fever, and leptospirosis are placing additional pressure on the state's healthcare system.
According to official health data, thousands of people have sought treatment for fever related illnesses in recent weeks. Health experts attribute the increase largely to heavy rainfall, waterlogging, and environmental conditions that favour the spread of infectious diseases.
One of the most worrying developments has been the emergence of Shigella infections in Wayanad district. The bacterial disease, which spreads through contaminated food and water, recently affected a large number of schoolchildren. More than a hundred students reported symptoms including fever, vomiting, stomach pain, and diarrhoea, leading to several hospital admissions. Health authorities quickly launched containment measures, including temporary closure of the affected educational institution and intensified monitoring in surrounding areas.
At the same time, health officials have reported a rise in cases of encephalitis, an inflammation of the brain that can be caused by viruses and other infections. The disease can lead to serious neurological complications if not detected and treated early. Medical experts say the appearance of encephalitis cases alongside other seasonal diseases has increased concern among public health authorities.
The state has also recorded a noticeable increase in deaths linked to infectious diseases compared with previous weeks. Health officials are closely studying the causes and patterns of these fatalities to strengthen prevention and treatment strategies. While authorities have not declared a public health emergency, hospitals and local health departments have been instructed to remain on high alert.
Dengue fever continues to be one of the most common diseases reported during the monsoon. Mosquito breeding in stagnant water has increased significantly due to continuous rainfall in many districts. Health workers are conducting awareness campaigns and urging residents to eliminate mosquito breeding sites around homes, schools, and workplaces.
Leptospirosis, commonly known as rat fever, remains another serious concern. The disease is spread through water contaminated by infected animal urine and often affects people who come into contact with floodwater or muddy environments. Agricultural workers, sanitation workers, and residents in flood affected areas are considered particularly vulnerable.
Adding to the concerns, Kerala's health authorities are also maintaining strict surveillance following reports of a suspected Nipah virus infection in Kozhikode district. Although confirmation is awaited, precautionary measures have already been implemented to prevent any possible spread of the deadly virus.
Health experts warn that the monsoon season creates favourable conditions for both waterborne and vector borne diseases. Contaminated drinking water, poor sanitation, and increased mosquito activity can accelerate the spread of infections if preventive measures are neglected.
The Health Department has urged people to seek immediate medical attention if they experience persistent fever, severe headache, vomiting, confusion, breathing difficulties, or other unusual symptoms. Officials have also advised the public to avoid self medication and follow proper hygiene practices.
Authorities continue to monitor the situation closely and have strengthened disease surveillance across districts. Hospitals have been instructed to ensure adequate availability of medicines, diagnostic facilities, and treatment services.
As Kerala experiences another intense monsoon season, health experts say public awareness, early diagnosis, and community participation will be essential in controlling the spread of infectious diseases and preventing further loss of life.
