Researchers have discovered a new coronavirus in bats in Brazil, showing a 72% genetic similarity to the MERS virus. The potential risks to humans are still unclear. Ongoing experiments at high-security laboratories in Hong Kong aim to assess these risks, emphasizing the need for continuous surveillance of bat populations for emerging viruses.
A novel coronavirus has been identified in bats in Brazil, showing significant genetic similarities to the Middle East respiratory syndrome (MERS) virus. This discovery was made by researchers from São Paulo and Ceará, working with Hong Kong University, highlighting a 72% genome similarity to MERS-CoV, which has caused over 850 deaths since it was first identified in 2012. The spike protein of the new virus aligns 71.74% with that of MERS, indicating possible interactions with human receptors.
Currently, scientists cannot confirm if this new virus can infect humans; however, parts of its spike protein suggest it may interact with similar receptors used by MERS-CoV. Planned experiments in high-security labs in Hong Kong aim to clarify these potential risks. According to researcher Dr. Ricardo Durães-Carvalho, ongoing monitoring is crucial to identify circulating viruses and assess transmission risks to other animals and humans.
In the study published in the Journal of Medical Virology, seven coronaviruses were identified from 423 bat swabs across 16 species collected in Fortaleza, northeastern Brazil. The newly discovered virus shares strong similarities with MERS-related coronaviruses found in humans and camels, and there is evidence of genetic recombination among these viruses, reflecting the diverse genetic landscape of coronaviruses.
Dr. Durães-Carvalho noted the importance of bats as viral reservoirs, emphasizing the need for continuous epidemiological surveillance. This research highlights the need for systematic and integrated virus analysis across various sectors, utilizing unified platforms for health systems to monitor and prevent potential epidemics and pandemics.
The recent discovery of a novel coronavirus in Brazilian bats, with notable similarities to the MERS virus, raises concerns about potential risks to humans, although these risks remain uncertain. The findings highlight the genetic diversity of coronaviruses and the critical role bats play as viral reservoirs. Continued surveillance and monitoring are essential for public health to prevent outbreaks associated with emerging viruses.
