A human disease can be triggered by the virus that is present in the outer environment. As study revealed, most of the virus responsible for human disease comes from animals and these viruses can affect an individual severely. Researchers have titled this great risk as zoonotic. It is assumed by the researchers that, post COVID-19, the next virus that can hit us is the zoonotic and this is one of the major risks that may affect human lives. People are already suffering from coronavirus pandemic and it has broken down several economies. A great depression has emerge which has created an imbalance between economies and due to this, many precious lives have been lost. Though, the zoonotic risk is of limited value and will not be able to evaluate which particular virus will bring a pandemic. For centuries, the so called zoonotic viruses have caused epidemics and pandemics in humans and it is being spectated that today COVID-19 pandemic is causing a great risk.
So an important question is whether we can predict which animal or group of viruses is likely to trigger the next pandemic. This has led researchers to attempt a "zoonotic risk prediction" which attempts to determine which virus families and host groups are most common. Dr. Wille and his colleagues identify several key problems in zoonotic risk prediction experiments. First, they are based on small data sets. Despite decades of effort, they have likely identified less than 0.001% of all cases. Second, this data is heavily focused on viruses that will infect most humans or farm animals. You have not been screened for viruses, and they are developing so rapidly that such research will soon be out of date and therefore of limited value. Each is necessary, which implies extensive sampling of animals and humans in the places where they interact with the animal-human interface. This will enable novel viruses to be detected as soon as they appear in humans and before they establish pandemics. Such enhanced surveillance may help us prevent something like COVID-19 ever happening again.
