There exists evidence that prion diseases may be transmissible by the airborne route. It is a type of transmissible spongiform encephalopathy (TSE). It was then recognized as a transmissible spongiform encephalopathy in 1978. Measles is the most contagious transmissible virus known. Antimicrobials against sexually transmissible pathogens should also be administered. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals. Syphilis was a stigmatized disease due to its sexually transmissible nature. Chancres transmit the sexually transmissible disease of syphilis through direct physical contact. Thus Sabin and Olitsky demonstrated "T. gondii" as a pathogen transmissible between animals. Transmissible diseases are quite common by European standards. H5N1 is easily transmissible between birds, facilitating a potential global spread of H5N1. The types of HPV that cause warts are highly transmissible. Overwhelming epidemiologic evidence suggests FeLV is not transmissible to either humans or dogs. KSHV is also transmissible via organ transplantation and blood transfusion. Recent strains of the bacteria, EMRSA-15 and EMRSA-16, are highly transmissible and durable.
