Childhood immunizations in the United States
Mumps is a contagious disease caused by the virus by the same name. Since most people in the United States have been vaccinated, mumps is now a rare disease in this country. Currently there are no specific treatments for mumps.
Mumps is spread person to person by droplets of saliva or mucus from the mouth, nose or throat of an infected person. This is done through coughing, sneezing, talking, and coming into contact with contaminate items. Transmission likely occurs before the salivary glands swell an up to 5 days after the swelling begins.
Orientia tsutsugamushi
The World Health Organization in 1999 stated that:
Scrub typhus is historically endemic to the Asia-Pacific region covering the Russian Far East and Korea in the north to northern Australia in the south and Afghanistan in the west, including islands of the western Pacific Oceans such as Japan, Taiwan, Philippines, Papua New Guinea, Indonesia, Sri Lanka, and the Indian Subcontinent. This geographic region is popularly called the Tsutsugamushi Triangle. However, it has spread to Africa, Europe and South America. One billion people are estimated to be at risk of infection at any moment and an average of one million cases occur every year in the Tsutsugamushi Triangle. In the absence of proper medical care, the case fatality rate can go beyond 30% to as high as 70% in some areas. The burden of scrub typhus in rural areas of Asia is huge, accounting for up to 20% of febrile sickness in hospital, and seroprevalence (positive infection on blood test) over 50% of the population. More than one-fifth of the population carry the bacterial antibodies, i.e., they had been infected, in endemic areas. South Korea has the highest level incidence (with its highest of 59.7 infection out of 100,000 people in 2013), followed by Japan, Thailand, and China at top of the list.
