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
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 ...
Zoonoses have different modes of transmission. In direct zoonosis the disease is directly transmitted from non-humans to humans through media such as air (influenza) or bites and saliva (rabies). [13] In contrast, transmission can also occur via an intermediate species (referred to as a vector), which carry the disease pathogen without getting ...
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]
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]
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 ...
Since the infected individual cannot swallow saliva and water, the virus has a much higher chance of being transmitted, because it multiplies and accumulates in the salivary glands and is transmitted through biting. [26] Hydrophobia is commonly associated with furious rabies, which affects 80% of rabies-infected people.
Andes virus has often been claimed by researchers to be the only hantavirus known to be spread from person to person, usually after coming into close contact with an infected person. It can also reportedly spread through human saliva, airborne droplets from coughing and sneezing, and to newborns through breast milk and the placenta. [2]
