RABIES AND ORGAN TRANSPLANT.

An investigation into the source of a fatal case of rabies virus exposure indicates that the individual received the virus through a kidney transplant 18 months earlier. 

 This findings suggests that rabies transmitted by this route may have a longer incubation period, and that although solid organ transplant transmission of infectious encephalitis is rare, further education to increase awareness is needed. The rabies virus causes a fatal encephalitis (inflammation of the brain) and can be transmitted through tissue or organ transplantation. 

The researchers found that in retrospect, the kidney donor's symptoms prior to death were consistent with rabies (the presumed diagnosis at the time of death was ciguatera poisoning [a foodborne illness]). 

 The Subsequent interviews with family members revealed that the donor had significant wildlife exposure, and had sustained at least 2 raccoon bites, for which he did not seek medical care. Rabies virus antigen was detected in archived autopsy brain tissue collected from the donor. 

The rabies viruses infecting the donor and the deceased kidney recipient were consistent with the raccoon rabies virus variant and were more than 99.9 percent identical across the entire N gene, thus confirming organ transplantation as the route of transmission. The 3 other organ recipients did not have signs or symptoms consistent with rabies or encephalitis.

 They have remained asymptomatic, with rabies virus neutralizing antibodies detected in their serum after completion of post-exposure prophylaxis. This transmission event provides an opportunity for enhancing rabies awareness and recognition and highlights the need for a modified approach to organ donor screening and recipient monitoring for infectious encephalitis. This investigation also underscores the importance of collaboration between clinicians, epidemiologists, and laboratory scientists . (culled from materials from American medical association.)

AVIAN INFLUENZA SURVEILLANCE EFFORTS.

The governments of Canada and British Columbia are investing CAD$ 300,000 (€200,000) to strengthen the surveillance, early detection, and response measures to avian flu. The funding will be used to enhance the resources at the Ministry of Agriculture's Animal Health Centre in Abbotsford, British Colombia with specialized equipment to diagnose samples collected in the Ministry's avian flu surveillance efforts. The Ministry of Agriculture will also be targeting owners of small poultry flocks by hosting workshops in different regions focusing on poultry health, and the sharing of information and resources such as the Small Flock Poultry Health Manual. Funds will also be used to support a rapid response to any future outbreaks by having mobile equipment to help any infected poultry premises with the humane depopulation of infected bird populations within the province at all times and to train more people in the use. Education about the virus and biosecurity procedures are paramount to prevention and spread of the bird flu virus.The basic clean, wash and disinfection on farms , better management practices and restriction of visitors to farms play vital roles to stem spread of diseases. Early detection/diagnosis is key to prevent incidence in other farms and wide spread infection over a wide radius range to prevent economic losses. Ministry of Agriculture staff began a pilot surveillance project that collected sediment samples at ponds and wetlands used by wild waterfowl following the December 2014 avian flu outbreak in the Fraser Valley. A research group has worked at developing cutting edge technological advances to be able to test the samples collected from the pilot project for the presence of avian flu strains. Funds will be used to transfer this new technology to the Animal Health Centre. As the pilot project evolves into ongoing surveillance, the ability to diagnose the samples quickly at the Animal Health Centre will greatly enhance early detection efforts.

EARLY DETECTION OF TUBERCULOSIS..

Tuberculosis a zoonotic disease and debilitating disease characterized by cough,muscle wasting,immuno suppression e.t.c.The prognosis of case is based on early detection,availability of drugs and frequency of use. The early detection of tuberculosis is vital to the success of treatment.
