The seasonal risk of Nipah virus
Nipah virus (NiV) is a zoonotic virus, meaning it is transmitted from animals to humans. It can also be transmitted through contaminated food or directly between people, according to World Health Organization.
It was first identified in Bangladesh in 2001. Since then, the Nipah virus has been prevalent in 31 south-western and north-western districts, during the time from December to March, according to the Institute of Epidemiology, Disease Control and Research (IEDCR).
The risk of people contracting the virus increases during winter, as cold creates a positive environment for such virus cultivation.
SYMPTOMS
Symptoms of Nipah virus infection are similar to those of influenzas, such as fever and muscle pain. In some cases, inflammation of the brain occurs, leading to disorientation or coma. Around half of the symptomatic cases are fatal.
PREVENTION
There is no vaccine available against the Nipah virus yet. So, as winter approaches, scientists every year issue cautions and recommend preventive measures for people to stay safe from the infection.
Some general measures to stay safe from the disease are:
1. Practice handwashing regularly with soap and water
2. Avoid contact with bats
3. Avoid areas where bats are known to roost
4. Avoid eating or drinking products that could be contaminated by bats, such as raw date palm sap, raw fruit, or fruit that is found on the ground
5. Avoid contact with the blood or body fluids of any person known to be infected with NiV
