Scientists have called for studying the spread of COVID19 across animal species, and between animals to humans, stressing the urgent need to assess the the impact of COVID19 transmission on food security.
The review research, published in the journal Vector-Borne and Zoonotic Diseases, identifies the urgent need to understand the ability of COVID19 to infect certain animals such as poultry, livestock, working animals like military service dogs, and other species in zoo.
According to the scientists, including those from the Western University of Health Sciences in the United States, there is also an critical need to assess transmissibility of the COVID19 infection between animals and humans.
The future for zoonotic SARS-CoV-2 to infect pets has been a topic of much argument, Stephen Higgs, Director of Biosecurity Research Institute in the U.S. said.
In this research, the scientists cited anecdotes of pets being infected with the COVID19, including the case of cat in Belgium.
Contrary to the earlier declaration by health agencies that COVID19 could not cause illness in pets, the cat developed both enteric and respiratory symptoms and took nine days to improve, the researchers mentioned in the research paper.
They said large amounts of antigen were repeatedly showed in the Cat's faeces and vomit over multiple days, which led researchers to culminate that the feline had been infected by COVID19.
Since Lions and Tigers in the United States zoo have tested positive for COVID19, the scientists said more questions need to be answered about duration of infection on animals, species susceptibility, viral shedding, and asymptomatic reservoirs of Coronavirus.
