Nadia, the tiger from the Bronx Zoo, was infected with the COVID-19 by an employee who had no symptoms yet, that is what the Bronx Zoo disclosed to us, but it was revealed that until now animals can be infected through of a human infected with the COVID-19 , but animals cannot infect humans, but it is something that is not yet confirmed, many will wonder how a contiguous human can infect an animal, an animal can become infected if an infected person has contact physical with the animal. The steps that will be used to prevent the spread of the COVID-19 are: cover your mouth and nose, wash your hands frequently and cover yourself with gloves, avoid physical contact, cover your face when coughing or sneezing, this is to prevent the spread or spread of the virus through respiratory drops that occur when an infected person sneezes or speaks. These drops can end up in people's mouths or nostrils, or they can be inhaled and reach the lungs. Perhaps the employee, who had no symptoms, was not cautious and had physical contact with the tiger and the contagion. We must take these precautions not to transmit it to people and animals.
