If Ebola hits Pakistan

The Ebola outbreak has claimed almost 5000 lives since March, the vast majority of them in West Africa with Liberia, Sierra Leone and Guinea being the worst hit. Even though Nigeria has been declared Ebola free by the WHO as of now, there is no vaccine or even a specific treatment for the virus which has a dismal survival rate of 37%. Infection produces a range of mild to deadly reactions in people from complete resistance, moderate to severe illness followed by recovery to excessive bleeding, organ failure and death. Like HIV, Ebola is not airborne. It is transmitted by touching the blood and body fluids of a patient as well as contaminated objects like needles.

Even though Ebola has mostly affected West Africa with only nine reported cases in the US and a few sporadic ones in Europe, most developed countries have stepped up their response to the deadly virus by implementing travel restrictions and mandatory quarantines of people returning from Ebola-stricken countries.

Interestingly, whereas a large part of the debate in western countries centers on implementing adequate measures to contain the virus without turning caregivers and patients into pariahs, in Pakistan the government evidently doesn’t think we are actually at any risk from this deadly disease at all. How else do you explain the fact that the government’s response to the virus has largely focused on bureaucratic measures involving the establishment of ‘steering committees’ and ‘focal persons’ which sound good on paper but are fairly ineffective without the mobilization of resources and some kind of accountability. Most airlines operating in the country’s airspace are not complying with national (Personal Declaration of Health and Origin Rule), and international requirements (International Health regulations 2005, International Civil Aviation Organization Regulation) of collecting information on passengers health status. Health forms are not always given out to passengers and even if duly filled are often not collected by airport authorities. Some like PIA and Shaheen Air International have reportedly refused medical examination of their food handlers. Moreover airport health departments are largely underfunded and understaffed. The department at Karachi airport has been denied a room in which to interview and examine incoming international travelers and an office at the cargo complex to examine goods due a lack of cooperation from the Civil Aviation Authority.

The problems of screening travelers at major airports is only the tip of the iceberg. What about those entering the country through numerous land and water routes?  And what happens if a patient is suspected of being infected? A quarantine facility set up in Bhitaiabad, Karachi for Ebola patients lacks basic protective measures for effective isolation defeating the whole purpose of setting up a quarantine. Refusing entry to suspected patients – as has happened in one reported incident- is not enough to contain the virus. Even if there are no symptoms of the disease at the point of entry to the country, people with a history of travel to infected areas need to be periodically monitored in case they develop symptoms. An infected person can escape detection at airport screening if they take fever reducing medication a few hours before landing. That is if we have functional screening processes at airports which currently we do not.

This kind of negligence is disturbing given that most experts have predicted that there will probably be a few cases in Asia before the year is out. China is particularly vulnerable due to its vast trading ties with West Africa. A large number of Chinese nationals working in Africa are due to return home for the Lunar New Year in the middle of February next year. However, China has experience in coping with contagion given the SARS outbreak in 2003. Next door, India has an effective tracking and control mechanism used to eliminate polio. In spite of these advantages these two countries which are at the highest risk of Ebola in Asia have been preparing their medical systems for the new threat. Ironically Pakistan which cannot even get a handle on polio is obviously not too bothered -even though an outbreak in the neighborhood will almost definitely transmit the disease to our soil. And lets not forget the thousands of Hajjis currently streaming back into the country after fraternizing with pilgrims from across the world.

Emergence of sporadic cases of Ebola do not necessarily lead to outbreaks as long as the necessary precautions are put in place. However, the key to Ebola control is to break the chain of contact. In the absence of a vaccine and effective treatment, protective measures are the only way to prevent the spread of this disease. While the news of recovering patients in the US and the recent declaration of Nigeria as officially Ebola free are heartening, we have to remember that the US has state of the art isolation facilities while Nigeria deployed personnel, technology and management methods used to combat polio to detect Ebola cases, trace contacts and implement quarantines. We can’t even eliminate polio- a disease that not only has a vaccine but is also far less deadly and infectious than Ebola. Forget polio, we can’t even manage dengue – a disease that follows predictable seasonal cycles and doesn’t spread by human contact. Imagine the devastation wrecked by something like the Ebola. Pakistan’s experience of the virus with its densely populated cities and towns and abysmal medical infrastructure will probably be similar to that of Liberia and Sierra Leone where the epidemic has reversed years of economic gains. Even the formulation of a vaccine is not a guarantee against an outbreak. Medicines and vaccines are only as good as their availability – as amply demonstrated by our inability to eradicate polio. In the case of Ebola prevention must be prioritized. We urgently need to mobilize our resources to detect and isolate cases because we are far from equipped to handle a full-fledged outbreak.
