A coronavirus is a group of viruses formed by a genetic material inside surrounded by an envelope of protein spikes. This gives it an appearance of a crown and crown in Latin is called the corona. The virus was first depicted in a group of people in Wuhan, China who were associated with seafood and live animal market. So, what is the origin of the virus? It is known that the coronavirus circulates in a range of animals, sometimes these viruses can jump from animals to humans. This is called spillover.
How is it transmitted?

From what is known so far there can be several symptoms that can be ranging from mild or severe. There could be fever or respiratory symptoms such as cough, shortness of breath and in severe cases it could be pneumonia, kidney failure and death. The mortality rate is the total number of deaths of a population, scaled to the total number of the population infected, per unit time. In this case, Globally, the mortality rate is about 3.4% of COVID-19.
Deaths can be more likely to happen in the elderly, with very low rates among younger people. Older people with diseases like diabetes, chronic respiratory diseases, cardiovascular disease, and cancer are more likely to get affected by the virus. The infection can be identified by a test called PCR or polymerase chain reaction. This test detects the virus based on its genetic fingerprint. There is currently no specific treatment to medication for the virus and treatment is supportive care. However, many ongoing clinical trials are evaluating potential vaccines.
Steps to follow or prevention of the virus
Several standard hygiene practices have been recommended to protect against infection and further spread these include:

The total patients hit by the virus are 409,054, the number of deaths is 18,262 and 107,073 have been recovered from this disease. The virus is spreading like wildfire and to stop that cities worldwide have been locked down.
Schools, cinemas, malls, restaurants, shops, and air travel, all have been shut down. A study has found that coronavirus may survive in a hot and humid climate. Doctors and researchers have analyzed the exact symptoms of COVID-19. The analysis revealed that 88% of fever, 67% of dry cough and 38% of fatigue is mandatorily seen in COVID-19 patients. Also, the majority of cases are only mild symptoms which are visible in 80% COVID-19 cases.
Generally, on average, it can take 5-6 days for symptoms to show up in your body but you are contagious. In Germany, there are 16,000 cases have been seen, there have been only 44 deaths. The death rate is merely 0.27%. In the UK, the death rate came out to be 4.47%. Whereas, in Italy, the death rate has reached up to 8.3%. Studies have found out that respiratory droplets from an infected person can persist in air, then the virus can survive 3 hours in the air. It can survive for 1 day on surfaces like cardboard and 3 days on plastic and steel.
