exposure to urine, feces, or saliva Marburg viral haemorrhagic fever: Marburg virus: Egyptian fruit bats (Rousettus aegyptiacus), non-human primates contact with infected bat excreta, bushmeat consumption, or human-to-human transmission via bodily fluids (e.g., blood, saliva, vomit) Mediterranean spotted fever: Rickettsia conorii
T. tenax is a commensal of the human oral cavity, found particularly in the patients with poor oral hygiene and advanced periodontal disease. Transmission is through saliva, droplet spray, and kissing or use of contaminated dishes or drinking water. [4]
Transmission occurs mainly through inhalation of aerosols that contain rodent saliva, urine, or feces, but can also occur through contaminated food, bites, and scratches. Vascular endothelial cells and macrophages are the primary cells infected by hantaviruses, and infection causes abnormalities with blood clotting , all of which results in ...

While usually caused by the Epstein–Barr virus, also known as human herpesvirus 4, which is a member of the herpesvirus family, [3] a few other viruses [3] and the protozoon Toxoplasma gondii [7] may also cause the disease. It is primarily spread through saliva but can rarely be spread through semen or blood. [2]
Some infectious diseases can be spread via respiratory droplets expelled from the mouth and nose, as when a person sneezes. A respiratory droplet is a small aqueous droplet produced by exhalation, consisting of saliva or mucus and other matter derived from respiratory tract surfaces. Respiratory droplets are produced naturally as a result of ...
It can reportedly spread through saliva, airborne droplets from coughing or sneezing, breastmilk, from mother to child across the placenta, and through the digestive tract. [4] [7] Person-to-person transmission reportedly occurs mainly within families or when engaging in close activities with an infected person during the prodromal disease ...
It can also reportedly spread through human saliva, airborne droplets from coughing and sneezing, and to newborns through breast milk and the placenta. [2] A 2021 systematic review, however, found human-to-human transmission of the Andes virus to not be strongly supported by evidence but nonetheless possible in limited circumstances, especially ...
