ABSTRACT
Coronavirus consists of single-stranded, enveloped and RNA virus, largest genome among all RNA viruses and has 4 proteins i.e. envelope, spike, nucleocapsid and membrane. Coronaviruses are classified into 4 genera: Alphacoronavirus, Betacoronavirus, Gammacoronavirus and Deltacoronavirus. Betacoronavirus most probably originated from bats and the virus may have jumped to avian species and evolved as Deltacoronavirus group. The avian coronaviruses jumped among other avian species, giving rise to Gammacoronavirus from Deltacoronavirus, while Betacoronavirus may have given rise to Alphacoronavirus. It is known that SARS-CoV-2 belongs to Betacoronavirus. This most similar virus is verified in bat and Malayan Pangolin. Analysis showed that SARS-CoV-2 most probably originated by recombination of both bat and pangolin viruses. Viral protein seroconversion and viral specific nucleotide positive documented in all COVID-19 patients tested provides confirmation of a link between the presence of this virus and the disease.
ABSTRACT
The Eastern Mediterranean Region (EMR) is facing extraordinary social and health challenges, aggravated by epidemiologic variations, high morbidity and mortality burden (communicable, noncommunicable, injuries), consequences of emergencies (including current COVID-19 pandemic), conflicts and massive migrant population movements. Research for health is essential for generating necessary evidence, which contributes to sustainable development, economic growth and sound health policy-making. Moreover, research for health that addresses national public health priorities is essential for developing required evidence for explanations that contribute towards health improvement and can assist in best utilization of available resources towards issues that maximize the research impact on population health.
