Orientobilharzia differ from Schistosoma only in the number of testes. The four species in this genus have recently (2012) been moved to the genus Schistosoma on the basis of morphology and molecular studies. [5] The genus name should now be regarded as a junior synonym of Schistosoma.
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels ( mesenteric veins ) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum , S. mekongi , S. guineensis , and S. intercalatum ).
A stool examination should be performed when infection with S. mansoni or S. japonicum is suspected, and a urine examination should be performed if S. haematobium is suspected. Eggs can be present in the stool in infections with all Schistosoma species. The examination can be performed on a simple smear (1 to 2 mg of fecal material).
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Reducing airborne transmission of COVID-19 indoors (video) This mode of transmission occurs via an infected person breathing out the virus, which is then carried by the air to a person nearby, or to someone across a room, who then breathes the virus in. Attempts to reduce airborne transmission act on one or more of these steps in transmission. [48]

Transmission from human to mink has occurred multiple times, in most cases not resulting in a sustained mink outbreak. [51] Strong evidence was seen of positive selection in mink after spillover, concentrated in the receptor binding motif. [67] Transmission back to humans has been documented for mink, hamsters, and cats. [66]
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
