Death from the outdoors....

From: Larry Trout

It's a disease more usually associated with the densely-packed cities of Europe in the middle ages, but health officials have confirmed a case of plague at South Lake Tahoe—the first in California in five years. The infected person is reportedly recovering at home. "Human cases of plague are extremely rare but can be very serious," El Dorado County Public Health Officer Dr. Nancy Williams said, according to CNN. Health officials believe the South Lake Tahoe resident may have been bitten by an infected flea while walking a dog along on Tahoe's south shore. The last reported human cases of plague in California were in 2015 when two people were exposed to infected rodents or their fleas in Yosemite National Park. Both recovered. Plague can successfully be treated with antibiotics, and, according to the CDC, treatment has lowered mortality rates to approximately 11 percent, with antibiotics working best if given within 24 hours of the first symptoms

The disease is spread by contact with fresh water contaminated with the parasites.[5] These parasites are released from infected freshwater snails.[5] The disease is especially common among children in developing countries, as they are more likely to play in contaminated water.

Schistosomiasis affected about 252 million people worldwide in 2015.[6] An estimated 4,400 to 200,000 people die from it each year.[7][8] The disease is most commonly found in Africa, Asia, and South America.[5] Around 700 million people, in more than 70 countries, live in areas where the disease is common.[7][11] In tropical countries, schistosomiasis is second only to malaria among parasitic diseases with the greatest economic impact.

Infected individuals release Schistosoma eggs into water via their fecal material or urine.[28] After larvae hatch from these eggs, the larvae infect a very specific type of freshwater snail. For example, in S. haematobium and S. intercalatum it is snails of the genus Bulinus, in S. mansoni it is Biomphalaria, and in S. japonicum it is Oncomelania.[29] The Schistosoma larvae undergo the next phase of their lifecycles in these snails, spending their time reproducing and developing. Once this step has been completed, the parasite leaves the snail and enters the water column. The parasite can live in the water for only 48 hours without a mammalian host. Once a host has been found, the worm enters its blood vessels. For several weeks, the worm remains in the vessels, continuing its development into its adult phase. When maturity is reached, mating occurs and eggs are produced. Eggs enter the bladder/intestine and are excreted through urine and feces and the process repeats. If the eggs do not get excreted, they can become engrained in the body tissues and cause a variety of problems such as immune reactions and organ damage.[citation needed]

Humans encounter larvae of the Schistosoma parasite when they enter contaminated water while bathing, playing, swimming, washing, fishing, or walking through the water
