"Nipah virus is a dangerous virus that can be transmitted from animals to humans and has a high mortality rate. The World Health Organization (WHO) lists Nipah as a priority disease to monitor due to the risk of a global pandemic."
How is it transmitted?
The virus can be transmitted through:
- Animals such as fruit bats and pigs,
- Food contaminated with bat secretions (especially raw date juice),
- Close contact with infected individuals.
It is most common in Bangladesh and India.
What are the symptoms?
Symptoms can range from mild to life-threatening:
- Fever, headache, muscle aches
- Vomiting, sore throat
- Dizziness, confusion
- In severe cases, brain inflammation (encephalitis), seizures, and coma
The incubation period is usually 4–14 days, rarely up to 45 days.
How Deadly?
The mortality rate for Nipah virus ranges from 40% to 75%, making it one of the deadliest viruses.
Is there a vaccine or treatment?
Currently, there is no vaccine or definitive cure. Treatment is limited to supportive care aimed at relieving symptoms.
Where has it been seen?
It first appeared in Malaysia in 1999. In recent years, the highest number of deaths has occurred in Bangladesh. In India's Kerala state, however, outbreaks were quickly brought under control thanks to rapid isolation and contact tracing.
Experts emphasize the great importance of adhering to hygiene rules and avoiding risky animal contact.
