The outbreak of the deadly Nipah virus around Kozhikode, Kerala, is a test of India’s capacity to respond to public health emergencies. In 2018, the World Health Organisation listed Nipah as one of the 10 priority(प्राथमिकता/अग्रता) pathogens(रोगजनकों) needing urgent research, given its ability to trigger lethal outbreaks and the lack of drugs available against it. As an RNA (ribonucleic acid) virus, Nipah has an exceptional(असाधारण/विशेष) rate of mutation — that is, it can easily adapt to spread more efficiently(कुशलतापूर्वक/फलोत्पदकता से) among humans than it does now. Such an adaptation(अनुकूलन/मेल) would result in a truly dangerous microbe. Nipah already kills up to 70% of those it infects, through a mix of symptoms that include encephalitis, a brain inflammation(सूजन/शोध) marked by a coma state, disorientation, and long-lasting after-effects, such as convulsions, in those who survive(जीवित रखना/बना रहना). Thankfully, in most outbreaks in South Asia so far the virus has displayed a “stuttering chain of transmission”. This means that once the virus spreads from fruit bats, its natural reservoir(जलाशय/संग्रह), to humans, it moves mainly to people in close contact with patients, such as hospital staff and family caregivers(देखभाल करने वालों।). But these caregivers are at high risk, because the sicker the patients become, the more virus they secrete. Preliminary reports suggest that the Kozhikode outbreak is also displaying a stuttering chain of transmission. Of the 11 confirmed Nipah fatalities(विपत्ति/मौत), three were from the same family. While researchers are still investigating how they were exposed, a bat colony living in a well in the family’s yard is a strong suspect.
This fits in with how outbreaks have historically(ऐतिहासिक दृष्टि से) begun in the subcontinent.(उपमहाद्वीप) In a 2007 outbreak in Nadia, West Bengal, for example, patient zero is believed to have acquired the virus from palm liquor contaminated by bat droppings. The next wave of infections have historically occurred among close contacts and caregivers, such as nurses; the same pattern has been detected in Kozhikode as well. But these are preliminary reports, and new information may change what we know about the present virus. Several patients with symptoms(लक्षण) of infection are under observation. Only when clinical investigations are complete can it be determined how contagious the virus really is. If it is found travelling over long distances, the authorities will have to be ready with strategies to combat its spread. The good news is that Kerala’s public health systems have acted with extraordinary efficiency so far. Doctors identified the virus in the very second patient, a diagnostic speed unrivalled(बेजोड़/बेमिसाल) in developing countries. This must be commended. But big challenges remain. The death of a nurse shows that health-care workers may not be taking adequate(पर्याप्त/उचित) precautions(सावधानियों) when dealing with patients, by using masks and following a strict hand-wash regimen. The virus has no specific treatment. The best defences against it are the age-old principles of infection control, which Indian hospitals have not mastered as yet. Kerala’s health authorities must ensure these principles are widely adopted, and no preventable(रोकने योग्य/निवारण करने योग्य)transmission takes place.
