How Does The COVID-19 Coronavirus Kill? What Happens When You Get Infected.
In severe cases, the viral infection moves from the nasal passage and throat to the lungs, where it can cause pneumonia and prove fatal. The coronavirus pandemic originated in China in late 2019 as a cluster of mysterious cases of pneumonia. The culprit was found to be a new type of virus, now called severe respiratory syndrome coronavirus 2, or SARS-Cov-2. The virus, and the disease it causes — COVID-19 — is fatal to a small percentage of the people it affects. Most of the danger is related to pneumonia, or an inflammation of the lungs caused by infection, although there is still much uncertainty about how the viral infection spreads and progresses in the body. The early symptoms are usually a cough, fever and shortness of breath, and look a lot like the flu or common cold. Symptoms appear 2-14 days after exposure. The virus circulates through droplets in the air spread by coughing or sneezing, and enters the body through the mouth, eyes or nose. It can remain viable on surfaces for hours to days, and may be able to enter the lungs directly when inhaled. After entering the body, the virus spreads to the back of the nasal passage and to mucous membranes in the throat, attaching to the body’s cell receptors. Credit: SCIENCE INSIDER
Poverty deprives people of adequate education, health care and of life's most basic necessities- safe living conditions (including clean air and clean drinking water) and an adequate food supply. The developed (industrialized) countries today account for roughly 20 percent of the world's population but control about 80 percent of the world's wealth.
Poverty and pollution seem to operate in a vicious cycle that, so far, has been hard to break. Even in the developed nations, the gap between the rich and the poor is evident in their respective social and environmental conditions.
