Abstract
Viruses are microscopic organisms that can only grow within living host cells. Various types of animals such as Rats, Bat, Cows, snakes, and related wild animals can serve as vehicles of transmission of this group of organisms. Novel SARS-CoV-2 belongs to the Coronaviridae family that was reported to have emanated from Wuhan, China in December 2019. It alerts world response against strange viral respiratory disease. As the world reflects on pandemics historically. Epidemics like the London plague of 1665 and the Plague that emanates from Marseille, France of 1720 claimed millions of lives. Among the most dreadful world pandemics are the “Antonine Plague” which occurred in 165AD and claimed 5 million lives in Egypt, Asia, Italy, and Greece. “Plague of Justinian” was reported to have occurred between the years 541 and 542. In addition to this, “The Flu Pandemic” is also referred to as Spanish flu ravaged the world during the year 1918 to 1920, which is about a century ago.”3rd Plague of 1855” originated from China and was responsible for the death of 10 million Indians within one year.” The Black Death” which is a 7 years long pandemic devastated the world between the years 1346 to 1353. It leads to the death of half of the global population and was by far the worst pandemic. HIV-AIDS has peak record deaths between 2005-2012. In the year 2019/2020 COVID-19 broke out severely than MERS-CoV and SARS-CoV which occurred in recent years. One possible best approach for the control of COVID-19 diseases caused by SARS-CoV-2 is to improve the hosts’ immune system. Evidence shows that inflammatory conditions militate against the immune systems of COVID-19 patients. Some other control strategies will include the use of face masks, physical distancing, hand washing, or use of alcohol-based sanitizers and related personal hygiene are important to contain the diseases.

Viruses are microscopic organisms that can only grow within living host cells in our diversified environment
And historically, many diseases have ravaged the world in form of pandemics in the past decades and centuries
Covid-19 which comes up with its own challenge starting from China, during the month of December, 2019 soar high during the year 2020
Summary
Viruses are microscopic organisms that can only grow within living host cells in our diversified environment They are unique in that they only replicate within the host cells to cause infection through their nucleic acid and related protein components with their encapsulated coat. The virus by their physiological nature are protein molecule (DNA) covered by a layer of lipid (fat) which protects the internal components. Viruses being a protein molecule is not killed but decay and disintegrate based on some environmental conditions like temperature and humidity It is very fragile, in that the outer layer is made up of fat which can be dissolved by heat and above 250C and alcohol based preparations made up of over 65% alcohol that is lethal for virus survival [1, 2]. Various types of animals such as Rats, Bat, Cows, Snake and related wild animals can serve as vehicle of transmission of this group of organism
