The outbreak of the deadly Nipah virus has claimed at least 13 lives in Kerala. According to the World Health Organization Nipah was first identified in 1999, the virus can be transmitted to humans from animals and is hosted by fruit bats. Absence of a vaccine to combat this killer disease has made the task of health officials extremely difficult.

Edited Excerpt:
Q: Do you feel absolutely confident that you have been able to now contain the spread of the deadly Nipah virus in Kerala?
A: No, I would not say we are absolutely confident. We have contained the first wave, but there is always a possibility of the contacts of the contacts, what we call the second wave, starting up. However, we are almost reaching the period within which this wave should have started up.
We have not seen signs of it, so, we are still keeping our fingers crossed. We are not calling the surveillance off, the whole missionaries is on active alert, but we are moderately hopeful that we have got out of the woods.
Q: Can you explain to us the measures that you have taken so far in order to contain the spread of the Nipah virus? Which are the agencies that you have worked with – international agencies, domestic agencies, and you said that you are not going to call the surveillance off just yet, what are the other remedial measures, precautionary measures that the state is putting in place to ensure that we do not see a repeat or in fact spread?
A: When we got notice of the case, we went back to the basics, that is we identified the index case and went about identifying all the contacts. I am happy to say that our team did such a good work that almost every case that has turned positive, figured in our contact list. That is the first thing which we did.
Then we went to the international agencies trying to find where it is that we could get help. We were lucky to get in touch with Professor Christopher Broder of Uniformed Services University of Health Sciences in US. Christopher has been one of the leaders in developing the cell-line and from that the monoclonal antibody. Meanwhile we also got in touch with the World Health Organisation (WHO).
Chris was able to put us in touch with the Queensland government who borrowed the cell-line from US, developed the antibody, and have stock filed the only monoclonal antibody that is believed to be an antibody to this virus. We got in touch with Queensland, Queensland said we will respond if the central government asks us.
Never before would have Indian Council of Medical Research (ICMR) moved so fast; we got the no objection from the Drug Controller General of India (DCGI), they moved the Queensland government, and we are at the final stage of getting those drugs in.
Meanwhile the WHO clinical development group has been made active again. We are working with them, the ICMR is working with them, and we are hopeful that going forward we should be able to see some active work, both on the drug development and on the vaccine development.
Going forward, what we would like to do us, we know that these bats are prevalent all across the country, and the bats carry infections below the detectable level. So, any part of India I would say is at risk. So what we will do is to identify the best persons working in this area in Asia, invite them over, do a study of our bat population and identify the infection root. We are also inviting the ICMR to join us and indications are the National Institute of Epidemiology under the ICMR would join us and together we will be able to ensure that the lessons that we learnt from this epidemic is available to us and for the rest of the country.
Q: I also want to understand about the practical reality on the ground. You talked about that surveillance system that you have put in place in order for you to be able to contain the spread of the virus. Can you explain to us because I would imagine that, that can also be important lesson for other states to follow through on, it must be a multi-thread surveillance system that you have put in place, can you explain to us how you brought about that and how it has been working on the ground?
A: Let us start before the epidemic got noticed because we know that this virus becomes active between December and May and what we will do in future is to start looking for this virus infections in future.
What happens now is, once case is identified then you do an active history taking, we look at all the contact who are there, find out how many other contacts they have had and what we did was to prepare a master list, advise our health field staff to contact each of them and advise them on house quarantine.
At one point of time we had more than 900 people who had been alerted and on house quarantine. Our field staff would call them up, visit them and find out if they are showing any symptoms. The moment they showed the symptoms, we would shift them to the facility we had identified and there they would remain under observation while we draw their blood, send it out for testing to our partner institute which is the Manipal Institute of Virology and the turnaround time was around 18 hours.
Within that time they remain there and if they are positive they are moved to the management facility, if they are not positive then they are sent home. That is the drill that we had followed and this is something we will try to refine in future if something happens again.
Q: In terms of being able to actively engage the local community to also ensure that precautionary measures are taken, I think that you have managed to do a fairly effective job this time around with the Nipah virus outbreak. Can you explain to us what specific measures were taken to engage the local community?
A: Kerala has a high level of social capital and the community generally rallies around when something like this happens. Secondly our elected representatives, we have gram panchayats and all the gram panchayats where the infections happened were very active and they ensured that the whole community was mobilised. The local MLA is one of our ministers, he was there right through the event.
The health minister was there right through the event. The media in Kerala has been very responsive, educating people on how the disease spreads, what measures to take, how not to panic. I would be very proud of the way that my whole state, the whole community, the media, the politicians, the health services, everybody pulled together to get us out of this problem.
