Abstract
Global public health is facing significant challenges in terms of emerging and re-emerging pathogens. The
world is facing a new public health crisis emergence and spread of Coronaviruses outbreaks especially
COVID-19 after nine deadliest viral outbreaks including Marburg virus, Ebola virus, Rabies, HIV,
Smallpox, Hantavirus, Influenza, Dengue and Rotavirus. Coronaviruses (enveloped non-segmented positivesense RNA viruses) belong to the Coronaviridae family, broadly distributed in humans as well as in other
mammals. In December 2019, the COVID-19 outbreak was reported in the Wuhan, Hubei province of China.
WHO confirmed that COVID-19 is associated with Huanan seafood (Wuhan). COVID-19 virus outbreak is more
dangerous than its ancestors MERS-CoV and SARS-CoV. Although the case fatality rate is lower, it has alarmed
the world because of its rapid spread during this era of the modern world where the whole world is connected
through different channels of trade. As the world is already facing economic challenges, underdeveloped
countries are not capable of facing such challenges, and this outbreak may become worse than ever before.
