All over the world, there is a new target of public health emergency looming the world along with an appearance and distribution of the novel coronavirus disease (2019-nCoV) also known as Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). This Virus initially generated in bats and then after transferred to a human being over unknown animal playing the role of mediator in Wuhan, China in December 2019. This virus is passed by breathing or in contact with an infected person’s droplets. The Incubation period is between 2 to 14 days for COVID-19, that is the time between exposure of the virus (person becoming infected) and symptom on that person, is on an average of 5-6 days, however it can goes up to 14 days. Throughout this period, which can be also known as “pre-symptomatic” period, some of the infected patients or persons can be contagious. That is why, transferal from a pre-symptomatic case can happen before the symptoms onset. Where there is few number of case studies and reports, pre-symptomatic transferal has been documented via contact with someone who is diagnosed with virus and increase investigation of that particular clusters of total confirmed cases. The main problem is that the symptoms are just like the regular flu that are cough, fever, sore throat, fatigue and breathlessness. This virus is moderate or mild in most of the people, but in elder ones, it may proceed to pneumonia, multi-organ dysfunction and Acute Respiratory Distress Syndrome (ARDS). Coronavirus has significant consequences on the Health system, mainly on cardiovascular diseases and on the environment.
