In the first scenario, the virus has evolved to its present pathogenic state by a natural transition from animal to human.

Shortness of breath is a unsafe symptom that can cause a downward spiral toward death. The overall molecular structure of this virus is distinct from the known coronaviruses and instead most closely resembles viruses found in bats and pangolins that had been little studied and never known to cause humans any harm.

Reports of the virus go all the way to December 2019, and ground zero for the outbreak was reported to be a live-animal market in Wuhan called the South China Wholesale Market.

Scientists from the National Institutes of Health, CDC, UCLA, and Princeton Universities have discovered that severe acute respiratory syndrome coronavirus 2 can remain stable for long periods of time on surfaces and in aerosols. On their online COVID-19 guide, they explained they have chosen to not use the term "SARS-CoV-2" because "using the name SARS can have unintended consequences in terms of creating unnecessary fear for some populations, especially in Asia which was worst affected by the SARS outbreak in 2003". A second outbreak of severe illness began in 2012 in Saudi Arabia with the Middle East Respiratory Syndrome (MERS). It has killed over 14,500 people and infected over 2.40 lakh people globally, according to the latest data from John Hopkins University's Coronavirus resource Center.

The most common symptoms are a dry cough, tiredness and a high temperature. To limit the virus spread, it is essential to avoid close contact with others who are sick, avoid touching the eyes, nose, and mouth, covering when sneezing or coughing and disposing the tissue properly, staying home when sick, self-isolating for those who are vulnerable, and cleaning or disinfecting frequently touched objects and surfaces, such as doorknobs, tables, and light switches.

Frequent hand washing with soap and water, use of an alcohol-based hand sanitiser and avoiding people who are unwell, are the best ways to prevent COVID-19.

According to the recent findings published in England Journal of Medicine, virus lives on cardboard up to 24 hours and up to 72 hours on plastic and steel.

As of Tuesday, the World Health Organization reports nearly 185 000 known cases of Covid-19 worldwide, including 7 529 deaths. But how do you distinguish a mild from a critical COVID-19 case?

While both of those epidemics died out, Covid-19 continues to spread worldwide. 3,245 deaths have occurred in China followed by 2,978 in Italy, 1,135 deaths in Iran, 638 in Spain, 264 deaths in France.

How is COVID-19 spread?

Out of the almost 32,000 active cases in the USA, 97% of them are considered mild cases, while only 3% are considered serious or critical. The phone number for the Arizona Health Department regarding COVID-19 is 480-303-1191.

Which population are at-risk for severe COVID-19?

However, clinical trials to test for COVID-19 have started in US. Health officials also noted that people could transmit the virus even if they have no symptoms, making contact tracing and virus spread control more hard and tedious.
