Dengue fever, transmitted by the Aedes aegypti mosquito, thrives in tropical and subtropical climates like West Bengal. The monsoon and post-monsoon seasons bring stagnant water—perfect breeding grounds for mosquitoes. Narayangarh and surrounding areas regularly report spikes in dengue cases during these periods, making public awareness and prevention critical.

Swine Flu, caused by the H1N1 influenza virus, is a contagious respiratory disease that emerged prominently in 2009 as a global pandemic. It spreads mainly through respiratory droplets when infected people cough or sneeze. Though initially alarming, continued awareness and vaccination have helped control outbreaks. However, sporadic cases and clusters continue to appear, especially in monsoon and winter seasons in India.

H3N2 is a subtype of the Influenza A virus, and one of the main viruses causing seasonal flu outbreaks in humans. While flu is a common viral illness, the H3N2 strain is known to be more aggressive, especially in the elderly, children, and people with respiratory illnesses. In the past year, India has seen a spike in H3N2 cases, leading to more hospitalizations compared to the typical flu season.

Nipah Virus (NiV) is a highly infectious and deadly virus transmitted from animals to humans, particularly fruit bats (flying foxes) and pigs. It can also spread through contaminated food and person-to-person contact. First identified in 1999 in Malaysia, the virus has caused repeated outbreaks in India, especially in Kerala and West Bengal — with mortality rates ranging from 40% to 75%.

As the monsoon season begins, parts of West Bengal and India are experiencing a rise in waterborne infections, especially Hepatitis A and Hepatitis E. These viruses primarily spread through contaminated food and water, and can cause serious liver inflammation. Unhygienic conditions, open drainage, street-side food, and improper sanitation are key drivers of this surge. Rural and semi-urban areas like Narayangarh are particularly vulnerable during this transition from summer
