The world is in the middle of the worst pandemic in recent history, as the strain of coronavirus Covid-19, spreads rapidly Starting from Wuhan, China in December 2019, the numbers are rising rapidly with every minute.

What makes it most dangerous is the fact that it can be spread by persons who do not show any symptoms. So a person sitting next to you or traveling with you may appear perfectly normal with no fever, cold, or cough, but he may be infected and be able to spread the disease This makes it impossible to prevent its spread except by mass isolation and close down, which is practically difficult.

Coronaviruses are enveloped RNA viruses. The most recent common ancestor (MRCA) of all coronaviruses probably existed around 8000 BCE Bats and birds are excellent hosts. The present types of coronaviruses were discovered in the 1960s and they cause respiratory tract infections. The word ‘corona’ originates from Latin, meaning ‘crown’ because the virus has an outer fringe resembling a crown.

The first lethal class of these viruses, the Severe Acute Respiratory Syndrome, SAR Cov, was detected in Guangdong, China, in November 2002 and it caused 8096 infections inhuman beings and 744 deaths. The second lethal type of coronavirus was the Middle East Respiratory Syndrome, MERS-CoV, that was detected in Jeddah Saudi Arabia in 2012. It caused2494 human infections and 858 deaths, a very high mortality rate of about 37 percent.

By far the fastest spreading of the three lethal types of coronaviruses, Covid-19, is the one affecting the world now. It was first detected in Wuhan China in December 2019 and there are already about 162,000 confirmed cases and over 6,000 deaths within about three months. It is spreading like wildfire all over the world which makes it the most dangerous of all varieties. It spreads by physical contact through exposure to droplets of water emitted by infected patients when sneezing or coughing and by physical touch to objects previously touched by infected patients.

The most dangerous feature of this virus is that patients suffering from this disease may not show any symptoms, such as fever, cold or cough, but they may still be able to infect others. This makes it impossible to prevent infected persons from crossing borders across countries unless one tests every single traveler, which is impossible.

The protective masks are to be worn by people only when they are in close contact with a suspected individual as Covid-19 travels in the form of droplets which are particularly for me when an individual coughs or sneezes. Proper masks of N95 or N-100 grading are not available locally, but other masks can also some protection.

COVID 19 is a pandemic now and requires actions at the local, regional, and global levels. However, surprisingly there is no global action on the horizon, Poor nations with weak healthcare systems and the inability to sustain a global lockdown will not able to fight this menace alone and will certainly need international assistance.
