Middle East Respiratory Syndrome Coronavirus Infection

Coronaviruses are a large family of viruses that cause a range of illnesses in humans and animals. The Middle East respiratory syndrome coronavirus (MERS-CoV) that causes MERS was first identified in 2012 in Saudi Arabia. Since then, globally, 635 laboratory-confirmed cases of infection with MERS-CoV have officially been reported to WHO, including 193 deaths. The affected countries in the Middle East include Jordan, Kuwait, Oman, Qatar, Saudi Arabia (KSA), United Arab Emirates (UAE) and Yemen; in Africa: Egypt and Tunisia; in Europe: France, Germany, Greece, Italy and the United Kingdom; in Asia: Malaysia and Philippines; and in North America: the United States of America (USA). All of the cases recently reported outside the Middle East (Egypt, Greece, Malaysia, the Philippines and the USA) recently travelled from countries inside of the Middle East (KSA or UAE). 

According to the Expert Meeting held in Oman recently, health experts and veterinarians are among those calling for stepped up monitoring, investigations, and immediate reporting of cases of the potentially fatal MERS, whose origins may be linked to animals. A declaration at a regional technical consultation meeting, convened by FAO and the Ministry of Agriculture and Fisheries of the Sultanate of Oman, warned countries in the region and beyond of the need for public health and veterinary authorities to carry out coordinated investigations, and share information and results. The majority of cases have occurred through human-to-human transmission, however it remains to be determined if people may have been infected by contact with environmental or animal sources. Several studies have reported high proportions of camels with antibodies against MERS-CoV or that of a closely-related virus, both in countries where human cases were detected and also in countries with no reported cases. Some of these studies have shown that MERS-CoV has been circulating in camels in Saudi Arabia since at least 1992. Genetic evidence of MERS-CoV infection was found in tests of camel samples from a farm in Qatar and in other studies in Egypt and Saudi Arabia.

India and WHO South-East Asia Region Certified Polio-Free

India as well as the WHO South-East Asia Region were certified polio-free on 27 March 2014 by an independent commission under the WHO certification process. WHO’s South-East Asia Region comprises 11 Member States: Bangladesh, Bhutan, Democratic People’s Republic of Korea, India, Indonesia, Maldives, Myanmar, Nepal, Sri Lanka, Thailand and Timor-Leste. With this step, 80% of the world’s population now lives in certified polio-free regions. Before a Region can be certified polio-free, several conditions must be satisfied such as: at least three years of zero confirmed cases due to indigenous wild poliovirus; excellent laboratory-based surveillance for poliovirus; demonstrated capacity to detect, report, and respond to imported cases of poliomyelitis; and assurance of safe containment of polioviruses in laboratories (introduced since 2000). Certification of the Region comes as countries prepare for the introduction of inactivated polio vaccine (IPV) in routine immunization as part of the eventual phasing out of oral polio vaccines (OPV). More than 120 countries currently use only OPV. These countries will introduce a dose of IPV by the end of 2015 as part of their commitment to the global polio endgame plan which aims to ensure a polio-free world by 2018.

Historically, India has been the largest endemic reservoir of polio in the world with between 50 000 to 100 000 paralytic polio cases occurring each year between 1978 and 1995. It has also been one of the main sources of polio importation for other countries. This achievement has been driven by the partnership between the Government of India, international organizations, local NGOs and other institutions. An extraordinary mobilization of health workers was necessary to reach this point, particularly in the Uttar Pradesh and Bihar states. The outcome of this has been an improved vaccine delivery system, better trained health staff and high quality surveillance, monitoring and research mechanisms. While celebrating the historic achievement, the Regional Director for the WHO South-East Asia Region, Dr. Poonam Khetrapal Singh, also sounded a word of caution to maintain high vigilance against importation of polio. “Until polio is globally eradicated, all countries are at risk and the Region’s polio-free status remains fragile. High immunization coverage can prevent an imported virus from finding an underimmunized, susceptible population. A sensitive surveillance system, able to quickly detect and identify any importation and guide a programmatic response, is critical,” she added.

Pathogens perpetuate by adapting themselves to a variety of environmental conditions and by moving from one infected host to another susceptible host. Many of these organisms affecting a large variety of animal species are also transmissible from these to man and vice versa. Such zoonotic pathogens circulating in animal population thus threaten not only animal health but also jeopardize public health. While developing countries including India are the hotspots of zoonotic diseases, developed nations too face a continuous threat from many emerging and re-emerging zoonoses. Predicting and controlling diseases at the human-animal interface is a huge challenge. Capacity building of individuals, groups, institutions, organizations and societies is essential to enhance their abilities in the area of surveillance, prevention and control of zoonotic diseases, agricultural development, food safety and food security. With One Health approach gaining momentum worldwide, integrated multidisciplinary coordinated approach assumes paramount importance in alleviating the sufferings and losses caused by zoonoses. 

This set of three books attempts to enrich all those having stake in the zoonoses control activities. Particular emphasis has been given to the risk analysis and strategies for zoonoses management in the developing nations. Equally useful to the students, teachers, researchers, academicians, policy makers and other professionals in the fields of animal health, public health, wildlife management and environmental health, these books will be a great tool for the professionals taking up advocacy, public awareness and health education programmes.

A person dies from rabies after trying to treat his son by sucking blood from dog-bite wound

A person died from rabies in China recently after he sucked blood from a bite wound inflicted by a stray dog on his son’s leg. He attempted this to remove any infection from the wound. The person was so anxious about his son’s injury that he squatted down immediately and started to suck the blood from the leg and spit it onto the ground, which some people do to try to treat bites from venomous snakes. Later, the son was given vaccine shots in the hospital but the father did not take vaccination due to cost considerations. He developed strong rabies symptoms and died hours after he was rushed to a hospital. Doctors reminded people not to suck out blood after being bitten by dogs, but to clean wounds with soapy water and get timely medical help.
