Abstract: According to the World Health Organization (WHO), viral diseases continue to emerge and represent a serious
issue to public health. In the last twenty years, several viral epidemics such as the severe acute respiratory syndrome
coronavirus (SARS-CoV) in 2002 to 2003, and H1N1 influenza in 2009, have been recorded. Most recently, the Middle East
respiratory syndrome coronavirus (MERS-CoV) was first identified in Saudi Arabia in 2012. The COVID-19 pandemic, also
known as the coronavirus pandemic, is an ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The outbreak was identified in Wuhan, China, in December
2019. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30
January, and a pandemic on 11 March. It is also named as Severe Pneumonia with Novel Pathogens on January 15, 2019 by
the Taiwan CDC, the Ministry of Health and is a notifiable communicable disease of the fifth category. COVID-19 is a
potential zoonotic disease with low to moderate (estimated 2%–5%) mortality rate. Person-to-person transmission may occur
through droplet or contact transmission and if there is a lack of stringent infection control or if no proper personal protective
equipment available, it may jeopardize the first-line healthcare workers. Currently, there is no definite treatment for COVID-
19 although some drugs are under investigation As of 6 May 2020, more than 3.66 million cases of COVID-19 have been
reported in over 187 countries and territories, resulting in more than 257,000 deaths. More than 1.19 million people have
recovered.
