Chapter 1 Host of Coronavirus Disease 2019 (COVID-19):

The medical community are in the learning curve to know about COV-19. Perhaps, it will probably take time to have the complete clinical picture in regards to COVID-19. Reported illness varies among the age groups based on individual immune systems and general health conditions. There are reports of infected persons having no symptoms and some about 16% or so showed severe illness resulting in death. Older people including the people of all ages with severe chronic medical conditions — like heart disease, lung disease and diabetes are obviously at higher risk of developing serious COVID-19 illness.The novel SARS-CoV-2 coronavirus first detected in the capital city of Wuhan, in the province of Hubei, China. After its first detection in last year it spread very fast to almost all countries in the world.

Where Did Viruses Come From? There is much debate among virologists about this question. Three main hypotheses have been articulated: 1. The progressive, or escape hypothesis states that viruses arose from genetic elements that gained the ability to move between cells; 2. the regressive, or reduction, hypothesis asserts that viruses are remnants of cellular organisms; and 3. the virus-first hypothesis states that viruses predate or coevolved with their current cellular hosts.[2]

1.0.1 Mission of Human Life:

Human kindom is blessed with plenty of foods, cultivating lands with crops and seeds, various kinds of trees with various kinds of fruits, sun is set in the right place to give us light and heat to keep us alive, seas & oceans with plenty of delicious fishes, atmosphere with perfect proporions of gases, rocks & minerals to support all inhabitants on Earth that include but not limited to man, women, children, animal kingdom,plants and trees. All these natural resources are mainly for material comfort and hapiness for human beings. Among all creations only humans have been created with a unique body and a unique mind. Keeping a balance between these two entities require wisdom to read and understand the genetic blueprint and human genome book. There are two approaches to read the book of life one through scientific exploration and another way is through your living wisdom, deep understanding of life, death and its consequences. We understand the action-reaction principle of Newton’s laws of kinematics. Similar to this principle human beings are subjected to accountability for their own deeds and conducts under “Golden Rule of Ethic”. About 10 percent of the world’s population live under extreme poverty with US$1.90 per day income. Poverty level is not even across all countries. In the Sub-Saharan Africa the poverty level is worse than the East Asia, Pacific, Europe and Central Asia. On top of poverty these countries having slow economic growth rates, don’t have access to good education, good environmental condition, a health care for all, no access to electricity, no safe drinking water and social and gender discrimiation. Many of us are living silently with hunger and malnutrition. They have no ability to raise their voices and messages to be propagated and understood by the people who are in authority. COVID-19 is a pandemic that scares off all nations in the world. Almost all countries have problems in regards to natural calamities, epidemic, wars, femine, drought, poitical and social unrest, ethnic and religious riots, social and economic injustice but lack of solidarity among the countries couldn’t make us united to eliminate these problems for creating a better world for living.
