New Coronavirus Strain Discovered in Brazil, Potential Human Infection Risks Uncertainty

A new coronavirus strain has been discovered in bats in Brazil, showing a 72% genetic similarity to the Middle East Respiratory Syndrome (MERS), which has a high fatality rate. Researchers from São Paulo and Ceará, in collaboration with the University of Hong Kong, identified the strain while conducting swabs on various bat species. The study's lead author, Dr. Bruna Silverio, noted that while it is unclear if the virus can infect humans, parts of its spike protein suggest it may interact with receptors similar to those used by MERS-CoV. The virus has been transported to China for further testing to assess its potential to infect human cells. This finding raises concerns about zoonotic diseases and highlights the importance of ongoing surveillance and research to prevent future outbreaks. Experts stress the need for vigilance given the historical precedent of coronaviruses jumping from animals to humans.
