          The emergence of the XBB.1.16 Omicron subvariant of COVID-19 has been a cause for concern for the WHO and health authorities globally. This subvariant, which originated from a hybrid of two BA.2 progeny pedigree, has two amino acid mutations in its spike protein and shares a genetic makeup similar to the XBB.1.5 variant. The WHO initially labeled it as a variant under monitoring before elevating it to a variant of interest after it was found to have caused a surge of COVID-19 cases in India for seven months. The XBB.1.16 subvariant has a proliferative edge and can evade the immune system. It has been spreading rapidly on a global scale and has been linked with a higher effective reproductive number than other subvariants. As such, a concerted international effort to prevent and contain its transmission has been recommended. Health authorities must strengthen their health systems, surveillance, and data collection systems to enable them to detect, track, and respond to emerging and reemerging strains of the virus in a timely and effective manner. Research into the XBB.1.16 subvariant is crucial for alerting and preparing the global populace for a potential outbreak, developing treatment options, and potential vaccines. Implementing the One Health approach can promote greater collaboration between diverse disciplines and societal levels to build a more resilient and sustainable future for all.

          The emergence of BtSY2 Covid-like virus: A call for global preparedness

          Scientists in China announced on 25th of November with great concern that there is a new Covid-like virus out of the five viruses of concern discovered among bats across Yunnan province. It was reported that this Covid-like virus BtSY2 has high potential of infecting humans as it comprises a receptor binding domain which is a vital part of the spike protein used to lay hold of human cells and subsequently utilize human ACE2 receptor for cell entry similar to the SARS-CoV-2. In a bid to address this global threat in affected countries , it is expedient for authorized health professionals, policy makers and the world to keep an eye on this Covid-like virus capable of spreading from bats to humans because most pandemic outbreaks in recent decades have arisen in such a manner. Strict actions should be implemented in impeding transmission to humans which is paramount to battling viral diseases as learnt from history that viral outbreaks are very impossible to eradicate after global outbreak. Health officials and the World Health Organization should invest urgently in more research to further study this new Covid-like virus with an approach to prepare for a possible viral outbreak, and develop treatment options and possible vaccines to outsmart the danger posed to human health.
