Covid 19 And Emerging Viral Diseases The Journey From Animals To March 22, 2020. blog. covid 19 and emerging viral diseases: the journey from animals to humans. by ziqi chen figures by rebecca senft. we live in a universe of viruses. it is estimated that there are billions of types of viruses on earth, and ~320,000 types that infect mammals alone.many viral species exist in our surrounding environment. The emergence of a new strain of severe acute respiratory syndrome coronavirus 2 (sars cov 2), which causes coronavirus disease (covid 19) has once again demonstrated the role of the family coronaviridae in causing human disease outbreaks. sars cov 2, a novel betacoronavirus, was identified in human patients from wuhan, china, during december.
Covid 19 And Emerging Viral Diseases The Journey From Animals To The emergence of a zoonotic pathogen in humans, such as sars cov 2, was not unpredicted. 1–3 of the novel or re emerging infectious diseases affecting humans in the 21st century, most (75%) have been zoonotic in origin, 4,5 with their natural reservoirs being other vertebrates. 6 the majority (over 70%) of these diseases with zoonotic origin have originated from wildlife, 7 such as hiv aids. These new technologies are being applied to emerging infectious diseases such as covid 19 or stubborn persistent challenges, including malaria and brucellosis 30,31,32,33. New human pathogens often emerge or re emerge from an animal reservoir, emphasizing the central role that non human reservoirs play in human infectious diseases. the 1918 pandemic of influenza virus a h1n1 and the 2020 pandemic of coronavirus disease 2019 (covid 19) are the most dramatic examples of this in recent human history. 3. covid 19 in animals. covid 19 is a zoonotic disease believed to have originated in animals . however, emerging studies have shown that the disease can also be transferred from infected humans to animals, such as domestic and nondomestic animals . bats are reservoirs for sars cov and other covs related to mers cov and sars cov .

The coronavirus that conquered the world came from a thumb sized bat tucked inside a remote chinese cave. of this much, scientists are convinced. exactly how and when it fled the bat to begin its devastating flight across the globe remain open questions. in one year, sars cov 2, the virus that causes covid 19, infected 94 million people and. Samples from the animals were sent to kurt vandegrift, a disease ecologist at pennsylvania state university who runs one of the world’s largest wildlife surveillance programs for sars‐cov‑2. its goal is to understand how the virus that causes covid 19 is spreading in north american wildlife, and how it might be evolving in its animal hosts.
