Warning of risk of COVID-19 transmission between humans and animals

In India, not only humans are infected with COVID-19 but eight lions in Nehru Zoo (NZP) are also infected with COVID-19. On the occasion of the above event, scientists warned that the risk of virus transmission between humans and animals is unavoidable.
Eight lions in Nehru Zoo get infected with COVID-19 from humans?

This is the second time this giant predator has been found to have COVID-19 after eight tigers and lions at Bronx Zoo, New York, USA, had similar results in April 2020. According to experts, it is likely that these lions were infected with COVID-19 from people working in the NZP, because more than 25 NZP staff has reportedly been infected with COVID-19 to date. NZP is a 54-hectare zoo, caring for more than 2,000 animals, the most visited place in India today. Because the incident on the NZP had to close and wait until further notice. Lions infected with COVID-19. Viruses can be transmitted from animals to humans and vice versa Many studies have found airborne transmission and animal-to-animal contact, from human to animal, and vice versa. Cats and weasels are the two animals most susceptible to SARS-CoV-2, while dogs are shorter; chickens, pigs and ducks are not infected. ZS-CoV-2 reverse transmission from animals to humans in dogs and cats has been confirmed by genetic analysis of virus strains isolated from domestic animals and domestic animals. Most studies show no clinical symptoms in infected dogs and cats. There is no evidence of animal-to-animal transmission of SARS-CoV-2, although this possibility is not excluded. COVID-19 in mink farms showed both human-to-mink transmission and vice versa. This raises concerns about weasels becoming an unexpected vector for SARS-CoV-2. According to three studies updated by the European Center for Infectious Diseases and Policy (CIDRAP), a high proportion of dogs and cats may have acquired COVID-19 from the owner, and the virus “jumps”. People and weasels go back and forth on farms in the Netherlands. Weasel is the most susceptible animal to SARS-CoV-2. First, a small study conducted by the University of Guelph in Ontario, Canada. As a result, most dogs and cats may have acquired COVID-19 from their owners, scientific evidence finds antibodies against SARS-CoV-2 in their blood. “Testing an animal’s blood after the owner has recovered is the best way to assess human-to-animal transmission because the time it takes to determine the current infection in the pet is narrow. There is sufficient evidence from many studies to recommend that people infected with SARS-CoV-2 should be isolated from humans and animals. Dr. Dorothee Bienzle, University of Guelph, key author. The second study was published in the journal Emerging Infectious Diseases late September 2020. Scientists in Hong Kong examined respiratory and fecal samples from 50 cats from COVID-19-infected households or their close contacts for SARS-CoV-2 RNA from November 11. 2 to 11/8/2020. 6 out of 50 cats (12%) tested positive for SARS-CoV-2 RNA on RT-PCR and the viral genome from a pair of hosts and cats were identical. All cats show no symptoms but have lung abnormalities similar to those found in infected people. The researchers call for broader serological monitoring of cats connected to COVID-19 patients to determine the incidence of human-to-cat transmission. The third study, presented at the ESCMID conference, monitored COVID-19 contamination in 16 mink farms with more than 720,000 animals in the Netherlands. As a result, SARS-CoV-2 was found to have “jumped” back and forth between people and weasels, in the case of animal-to-human transmission or vice versa. Researchers who examined and sequenced the entire genome showed that 66 out of 97 people (67%) who lived or worked on farms were diagnosed with COVID-19 on PCR or a resistance test. can. Currently, COVID-19 is still spreading in farms, despite human efforts, the authors reveal. In order to minimize the risk of transmission of the virus between humans and animals and vice versa, scientists argue that close cooperation between animal health agencies and people is essential for early identification and control of schools. infection with SARS-CoV-2. Cats need to be isolated to prevent infection with SARS-CoV-2. In addition, to avoid transmission of the virus from infected households and pets to livestock, the livestock must be in the same quarantine as applies to humans. Letting your pet roam in a community increases the likelihood of spreading the virus. The original origin of the virus has not been determined yet, so livestock should be strictly managed and all measures are taken according to the veterinary authorities, especially pets in areas where epidemics have occurred. and has been translated.
