Coronavirus News: Middle-east researchers from the American University of Beirut-Lebanon and Qatar University-Doha say that the SARS-CoV-2 coronavirus that caused the COVID-019 disease will ultimately become a seasonal virus just like influenza but not just yet. It only till a global herd immunity is achieved that will this happen.


 
Their review was published in the journal: Frontiers in Public Health  https://www.frontiersin.org/articles/10.3389/fpubh.2020.567184/full
 
The (RO) or basic reproduction number is the number of secondary cases resulting from a primary case in a susceptible population and is an important indicator to predict the spread of a virus. For a virus to follow a seasonal pattern, and thus wane in summer, its effective R0 should drop below 1.
 
Currently for SARS-CoV, the R0 is estimated between 2 and 3 and in some estimates as high as 5.7. Several factors in the summer might reduce the effective R0 of respiratory viruses including the effect of warm temperatures and humidity on the stability of the virus and susceptibility of the host as well as behavior of the population such as indoor crowding.
