Elimination of human rabies in Goa, India through an integrated One Health approach.

Dog-mediated rabies kills tens of thousands of people each year in India, representing one third of the estimated global rabies burden. Whilst the World Health Organization (WHO), World Organization for Animal Health (OIE) and the Food and Agriculture Organization of the United Nations (FAO) have set a target for global dog-mediated human rabies elimination by 2030, examples of large-scale dog vaccination programs demonstrating elimination remain limited in Africa and Asia. We describe the development of a data-driven rabies elimination program from 2013 to 2019 in Goa State, India, culminating in human rabies elimination and a 92% reduction in monthly canine rabies cases. Smartphone technology enabled systematic spatial direction of remote teams to vaccinate over 95,000 dogs at 70% vaccination coverage, and rabies education teams to reach 150,000 children annually. An estimated 2249 disability-adjusted life years (DALYs) were averted over the program period at 526 USD per DALY, making the intervention 'very cost-effective' by WHO definitions. This One Health program demonstrates that human rabies elimination is achievable at the state level in India.

The Middle East and Eastern Europe rabies Expert Bureau (MEEREB) third meeting: Lyon-France (7-8 April, 2015).

MEEREB is an inter-regional network of countries from North Africa, Europe, the Middle East and Central Asia that work together with the aim of improving rabies control and prevention at local, regional and global level. MEEREB members met for the third time in 2015 in France (Lyon) to review the current rabies situation within the network and to discuss the way forward the prospect of a One Health approach against rabies. Dogs were the main vector of transmission in all MEEREB countries except for Croatia and Serbia where foxes represented the primary source. The number of rabies animal cases reported in 2014 varied substantially between countries with Ukraine reporting the highest number of animal cases. Human cases still occur in North Africa and all Middle East and Eurasian countries while no cases of human rabies were reported in Croatia, Serbia and Romania, although cases of rabies were identified in both dogs and foxes in 2014. Participants concluded that MEEREB can act as a think-tank where countries can share data, information, experiences and best practices to jointly address challenges in rabies control and prevention. They called for elimination of dog-transmitted rabies through vaccine and rabies immunoglobulin stockpiles and implementation of a One Health approach to achieve rabies's eradication.

A longitudinal study of the prevalence of Nipah virus in Pteropus lylei bats in Thailand: evidence for seasonal preference in disease transmission.

After 12 serial Nipah virus outbreaks in humans since 1998, it has been noted that all except the initial event in Malaysia occurred during the first 5 months of the year. Increasingly higher morbidity and mortality have been observed in subsequent outbreaks in India and Bangladesh. This may have been related to different virus strains and transmission capability from bat to human without the need for an amplifying host and direct human-to-human transmission. A survey of virus strains in Pteropus lylei and seasonal preference for spillover of these viruses was completed in seven provinces of Central Thailand between May 2005 and June 2007. Nipah virus RNA sequences, which belonged to those of the Malaysian and Bangladesh strains, were detected in the urine of these bats, with the Bangladesh strain being dominant. Highest recovery of Nipah virus RNA was observed in May. Of two provincial sites where monthly surveys were done, the Bangladesh strain was almost exclusively detected during April to June. The Malaysian strain was found dispersed during December to June. Although direct contact during breeding (in December to April) was believed to be an important transmission factor, our results may not entirely support the role of breeding activities in spillage of virus. Greater virus shedding over extended periods in the case of the Malaysian strain and the highest peak of virus detection in May in the case of the Bangladesh strain when offspring started to separate may suggest that there may be responsible mechanisms other than direct contact during breeding in the same roost. Knowledge of seasonal preferences of Nipah virus shedding in P. lylei will help us to better understand the dynamics of Nipah virus transmission and have implications for disease management.

First report of chikungunya from the Maldives.

An outbreak, characterised by fever, arthralgia and myalgia, in Malé and other islands of the Maldives began in December 2006. The illness was suspected as being due to chikungunya virus based on clinical symptoms and the prevailing chikungunya epidemic in the Indian Ocean region. The Department of Public Health initiated an investigation and collected blood samples from 67 patients; 21% were IgM-positive for chikungunya and 96% were PCR-positive. Six percent were positive for dengue by enzyme immunosorbent assay and 4% had evidence of dual infection. This is the first time that chikungunya fever has been confirmed in the Maldives. A total of 11,879 suspected and confirmed cases affecting 61% of inhabited islands (attack rate ranging from 0% to 72% on individual islands) were reported by the end of the epidemic in April 2007.
