• Leptospirosis is a disease that is caused by
spirochete bacteria in the genus Leptospira.
There are 10 pathogenic species, and more
than 250 pathogenic serovars.
• While leptospirosis occurs worldwide, it is
more common in tropical or sub-tropical
climates.
Onchocerciasis, or river blindness, is a neglected tropical disease (NTD) caused by the parasitic worm Onchocerca volvulus. It is transmitted through repeated bites by blackflies of the genus Simulium. The disease is called river blindness because the blackfly that transmits the infection lives and ...breeds near fast-flowing streams and rivers, mostly near remote rural villages. The infection can result in visual impairment and sometimes blindness. Additionally, onchocerciasis can cause skin disease, including intense itching, rashes, or nodules under the skin. Worldwide onchocerciasis is second only to trachoma as an infectious cause of blindness.

Scabies is an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most common symptoms of scabies are intense itching and a pimple-like skin rash. The scabies mite... usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies.

Each year, rabies causes approximately 59,000 deaths worldwide. Despite evidence that control of dog rabies through animal vaccination programs and elimination of stray dogs can reduce the incidence of human rabies, dog rabies remains common in many countries and exposure to rabid dogs is still the ...cause of over 90% of human exposures to rabies and of 99% of human rabies deaths worldwide. CDC experts in the Poxvirus and Rabies Branch conduct an annual assessment of individual countries’ rabies status worldwide which considers the presence of wildlife rabies, canine rabies variant (dog rabies), and non-rabies lyssaviruses.

A regimen of four 1-mL doses of HDCV or PCEC vaccines should be administered intramuscularly to previously unvaccinated persons.
The first dose of the four-dose course should be administered as soon as possible after exposure. Additional doses should be administered on days 3, 7, and 14 after the... first vaccination. For adults, the vaccination should always be administered intramuscularly in the deltoid area (arm). For children, the anterolateral aspect of the thigh is also acceptable. The gluteal area should never be used for rabies vaccine injections because observations suggest administration in this area results in lower neutralizing antibody titers.

CDC’s Lauren Greenberg writes about building rabies diagnostic capacity in the effort to control rabies in countries that are most affected by the disease.
Leishmaniasis is found in people in focal areas of approximately 90 countries in the tropics, subtropics, and southern Europe. The ecologic settings range from rain forests to deserts. Leishmaniasis usually is more common in rural than in urban areas, but it is found in the outskirts of some cities.... Climate and other environmental changes have the potential to expand the geographic range of the sand fly vectors and the areas in the world where leishmaniasis is found.
