CORONA VIRUS:-

                                 Coronaviruses are named for the spikes that protrude from their surfaces, resembling a crown or the sun’s corona. They can infect both animals and people and can cause illnesses of the respiratory tract.
At least four types of coronaviruses cause very mild infections every year, like the common cold. Most people get infected with one or more of these viruses at some point in their lives.
Another coronavirus that circulated in China in 2003 caused a more dangerous condition known as Severe Acute Respiratory Syndrome or SARS. The virus was contained after it had sickened 8,098 people and killed 774.
Middle East Respiratory Syndrome, or MERS, first reported in Saudi Arabia in 2012, is also caused by a coronavirus.
The new virus has been named SARS-CoV-2. The disease it causes is called COVID-19.
How dangerous is it?
It is hard to accurately assess the lethality of a new virus. It appears to be less often fatal than the coronaviruses that caused SARS or MERS, but significantly more so than the seasonal flu. The fatality rate was over 2 percent, in one study. But government scientists have estimated that the real figure could be below 1 percent, roughly the rate occurring in a severe flu season.
About 5 percent of the patients who were hospitalized in China had critical illnesses.
Children seem less likely to be infected with the new coronavirus, while middle-aged and older adults are disproportionately infected.

Men are more likely to die from infection compared to women, possibly because they produce weaker immune responses and have higher rates of tobacco consumption, Type 2 diabetes and high blood pressure than women, which may increase the risk of complications following an infection.
“This is a pattern we’ve seen with many viral infections of the respiratory tract — men can have worse outcomes,” said Sabra Klein, a scientist who studies sex differences in viral infections and vaccination responses at the Johns Hopkins Bloomberg School of Public Health.

WHO (WORLD HEALTH ORGANIZATION) SAYS:-
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.  Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illnesses.
The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol-based rub frequently and not touching your face. 
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).
At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments. WHO will continue to provide updated information as soon as clinical findings become available.

How is the new coronavirus transmitted from animal to human?

Experts believe that an infected animal may have first transmitted the virus to humans at a market that sold live fish, animals, and birds in Wuhan. The market was later shut down and disinfected, making it nearly impossible to investigate which animal may have been the exact origin. Bats are considered a possible source, because they have evolved to coexist with many viruses, and they were found to be the starting point for SARS. It is also possible that bats transmitted the virus to an intermediate animal, such as pangolins, which are consumed as a delicacy in parts of China, and may have then passed on the virus to humans.
SYMPTOMS OF CORONA VIRUS BY WHO:-
The COVID-19 virus affects different people in different ways.  COVID-19 is a respiratory disease and most infected people will develop mild to moderate symptoms and recover without requiring special treatment.  People who have underlying medical conditions and those over 60 years old have a higher risk of developing severe disease and death.
Common symptoms include:
  • fever
  • tiredness
  • dry cough.
Other symptoms include:
  • shortness of breath
  • aches and pains
  • sore throat
  • and very few people will report diarrhea, nausea or a runny nose.
People with mild symptoms who are otherwise healthy should self-isolate and contact their medical provider or a COVID-19 information line for advice on testing and referral.
People with fever, cough or difficulty breathing should call their doctor and seek medical attention.
In symptoms of coronavirus if found in any human and their symptoms are described below.
FEVER;-87.9%
DRY COUGH:-67.7%
FATIGUE:-38.1%
SPUTUM PRODUCTION:-33.4%
SHORTNESS OF BREATH:-18.6%
MUSCLE OR JOINT PAIN:-14.8%
HEADACHE:13.6%
CHILLS:-11.4%
NAUSEA OR VOMITING:-5%
NASAL CONGESTION:-4.8%
DIARRHEA:-3.7%
HOW TO TRANSMIT THIS VIRUS HUMAN TO HUMAN:-
* By people to people meet each other, handshaking, a group discussing, playing and many more.
*By Air sneeze, cough threw outing, smoking and many more.
*By clothing wearing without cleaning, using a used handkerchief.
*By traveling.
PREVENTION OF COVID-19
To prevent infection and to slow transmission of COVID-19, do the following:
  • Wash your hands regularly with soap and water, or clean them with alcohol-based hand rub.
  • Maintain at least 1-meter distance between you and people coughing or sneezing.
  • Avoid touching your face.
  • Cover your mouth and nose when coughing or sneezing.
  • Stay home if you feel unwell.
  • Refrain from smoking and other activities that weaken the lungs.
  • Practice physical distancing by avoiding unnecessary travel and staying away from large groups of people.
COVID-19 IS SPREADING IN FOUR BASIS STEPS 

Taxonomy

Coronaviruses and toroviruses are two virus genera within the virus family Coronaviridae, order Nidovirales. Coronaviruses are well-established pathogens of humans and animals while the toroviruses are recognized as causes of animal diarrhea. Toroviruses have also been found in human feces but their aetiological role remains unclear.
Coronaviruses are classified into three groups, initially based on antigenic relationships of the spike (S), membrane (M) and nucleocapsid (N) proteins and now re-enforced by viral genetic phylogeny (Box 57.1). The HCoVs 229E and NL63 are group 1 coronaviruses, while OC43, HKU-1, and SARS coronaviruses are classified in group 2. Group 3 coronaviruses are found in avian species. Genetic recombination readily occurs between members of the same and of different coronavirus groups providing the opportunity for increased genetic diversity.
Efforts to identify the animal reservoir of SARS coronavirus led to the discovery of diverse bat coronaviruses in both group 1 and 2 that are closely related phylogenetically to different mammalian coronaviruses. It has been proposed that bat coronaviruses may indeed have been the ancestors of many mammalian coronaviruses. It is noteworthy that recent studies on the comparative evolution of animal and human coronaviruses have led to the conclusion that HCoV 229E and OC43, the causes of the common cold which are now globally endemic in humans, crossed species from their animal reservoirs (bats and cattle, respectively) to humans within the last 200 years, illustrating the fact that coronaviruses continue to cross species barriers and cause novel diseases.
VACCINES OF CORONA VIRUS OR COVID-19
At this time, there are no specific vaccines or treatments for COVID-19. However, there are many ongoing clinical trials evaluating potential treatments.
