Nipah Virus Update Over 100 Quarantined After Hospital Linked Outbreak, State Issues Emergency Measures
A new outbreak of Nipah virus has sent shockwaves across West Bengal, as there was a suspected hospital premises outburst in the North 24 Parganas district that caused the quarantine of more than 100 individuals, including healthcare workers, family members, and close contacts. When the case was escalating with infected medical staff being moved into a specialised infectious diseases hospital in Kolkata, emergency health guidelines were issued by the state authorities, further contact tracing was intensified, and various districts were put on high alert to check the spread of the deadly virus further.The recent events emphasise the rate at which the Nipah virus can be transmitted in closed environments, and especially in healthcare facilities, and thus awareness among people is really important.
Nipah virus, NIV, is a very contagious zoonotic virus that can be transmitted by animals to humans. Being a henipavirus, it is characterised by a high level of fatality that may range between 40 to 70 and more as per outbreak and access to appropriate medical treatment.The natural host of the virus is fruit bats, especially the flying fox. Although bats do not display any symptoms, the virus has the ability to directly and indirectly jump to humans or intermediate hosts. It is believed that Nipah is particularly dangerous as it can attack the respiratory system as well as the brain, with fatal outcomes in most cases.
There are numerous ways in which the nipah virus is transmitted:
The natural host of the Nipah virus is the fruit bat, flying foxes, which loves the sap of date palm. Sap is frequently licked at night, as well as urinated into the collection pots. This has the potential to pollute the sap with bat saliva, urine, or droppings, which might have the virus.
Nipah virus can survive and enter the human body directly when the unboiled or raw date palm sap is consumed. This risk can be mitigated by heating or fermenting the sap, however raw sap is not capable of protecting against infection.
Several outbreaks of Nipah have been associated with individuals who ate fresh, raw sap of date palm. Medical experts continually use it as one of the most prevalent and avoidable agents of the Nipah virus animal to human spillover.
No established treatment or vaccine for Nipah virus infection is approved at the moment. Since it has a high fatality rate, prevention such as avoiding known exposure routes such as taking the sap during its raw form, is one of the best preventive strategies.
However, date palm sap is primarily gathered and eaten during the winter seasons, and it is also one of the seasons when bats are particularly active around the location of sap collection, which also increases the chances of contamination.
Hospitals in West Bengal have been trained to isolate suspected patients, make them wear PPE, restrict unnecessary visits and tighten infection-control measures.
One may require immediate medical attention if they experience symptoms that are linked to Nipah virus infection. You should see a doctor if experiencing any of these symptoms.
Overall, the Nipah virus does not have a particular antiviral therapy or any approved vaccine. Therapy is more primarily supportive in aiming at the management of symptoms, respiratory support, and secondary inhibition of infections.
