Heavy monsoon rains lead to water accumulating in containers, puddles, drains, and other areas, becoming breeding sites for mosquitoes.
The monsoon season brings with it the promise of rejuvenated landscapes and much-needed relief from the summer heat.
However, it also heralds the arrival of potential health challenges in the form of communicable diseases.
The rains — while refreshing — create a fertile breeding ground for mosquitoes and waterborne pathogens, making it imperative for communities to brace themselves against the surge of monsoon-related diseases.
The Hyderabad office of the India Meteorological Department (IMD) predicted light to moderate rain or thundershowers likely in isolated places over Telangana, bringing relief from the heat.
Telangana’s Health Department said in a statement on Tuesday, 21 May, that the moderate temperatures and humidity were also “a breeding ground for various viral infections as well as mosquito, food, and water-borne diseases.”
“The high moisture content in the air allows harmful microorganisms to thrive, leading to the transmission of a range of diseases through different mediums — such as mosquitoes, water, air, and contaminated food,” said Hyderabad-based physician Dr Vamsi Krishna.
Mosquitoes — particularly the Aedes aegypti and Anopheles species — lay their eggs in stagnant water.
The heavy rain of the monsoon season leads to water accumulating in containers, puddles, clogged drains, and other areas, providing perfect breeding sites for these insects.
“High humidity levels extend the lifespan of mosquitoes, allowing them more time to breed and spread diseases. Mosquitoes are more active and feed more frequently in these conditions, increasing the likelihood of disease transmission,” said Krishna.
He added that humidity promotes the growth of fungi, which can lead to skin infections like athlete’s foot and ringworm.
Humid conditions can exacerbate respiratory issues and create environments conducive to the spread of viral infections such as the common cold and influenza.
“Many pathogens thrive in moderate temperatures, enhancing their survivability in water and food. This can lead to an increase in gastrointestinal infections and waterborne diseases,” said Krishna.
He added that heavy rains can overwhelm sewage systems, leading to the contamination of water supplies with faecal matter.
“This contamination can result in the spread of diseases like leptospirosis and gastroenteritis. Stagnant water also supports the growth of bacteria and viruses that can contaminate drinking water sources, leading to diseases such as cholera, typhoid, and hepatitis A and E,” he said.
To guard against these, the Telangana Health Department has provided a few tips to stay healthy during the rains:
Battling the mosquito menace:
Prevent water-borne infections:
Guard against airborne infections:
“As a part of precautionary measures, the government has made elaborate arrangements by providing special beds, IV fluids, and essential medicines at all the public health facilities,” said the Health Department.
“ORS sachets are made available with ANMs/ASHAs/Anganwadi workers to meet any exigencies,” it added.
