emerging viruses

Emerging viruses are new or recently increased viruses that can cause illness in people. They often originate from animals, mutate or adapt, and find ways to infect humans who previously had little or no immunity. These viruses can spread quickly, sometimes leading to outbreaks or pandemics. Examples include the viruses behind COVID-19 and Ebola. Monitoring and understanding emerging viruses helps scientists develop vaccines, treatments, and strategies to prevent their spread, protecting public health.
