What are viruses ?
Viruses literally mean substances that are full of toxins. Virus is a type of no cellular (acellular) substance. It is considered to be the link between the living and the non-living. They are made up of only nucleic acids (DNA / RNA) and capsids (proteins and lipids). They do not have a nucleus. The virus was discovered in 1892 by Russian scientist Dimitri Ivanoski. He identified the virus while studying the disease occurring in tobacco leaves. This virus is called tobacco mosaic virus (TMV).

Note:- Long before the discovery of the virus, Louis Pasteur discovered the vaccine for rabies, which is spread by the virus.

As long as the viruses live in the outdoor environment, they remain lifeless. They can be stored in bottles like inanimate material and kept for years. As soon as the virus enters the body of an organism, it reaches the nucleus of the body's cells and starts doubling its nucleic acid (DNA / RNA). Cell division occurs all the time in our body. Therefore, along with cell division, these viruses also begin to divide and spread to all parts of the body.

Note:- As soon as the virus enters the living organism, the antibodies start destroying lymphocytes (a type of WBC). Due to which the body's immunity starts decreasing. Then the virus easily makes its home in the living organism's body and starts harming various body parts.

Corona viruses are a large family of viruses that are known to cause illness ranging from the common cold to more severe diseases. Corona viruses are zoonotic viruses. That means they commonly affected by animals; such as: birds, bats, camels and pigs; which makes it very dangerous disease.
According to the Centers for Disease Control and Prevention (CDC), corona viruses occasionally cause complications in the lower respiratory tract, such as pneumonia.

*Corona viruses mostly affect infants, older adults and the people with other illnesses or weakened immune systems.

Corona: Symptoms of corona virus
Generally dry cough, shortness of breath, fatigue, fever, nasal congestion, sore throat and headaches.

Severe infection can cause other life-threatening conditions, such as:- pneumonia, kidney failure, usually death as a result of respiratory failure.  

There are hundreds types of corona viruses, but only seven types of theme are known to affect people. Four human corona viruses only cause mild-cold or flu-like symptoms. Three other corona viruses pose more serious risks like severe diseases. All seven types of human corona viruses cause upper respiratory infections. Its symptoms may include nasal congestion, sore throat, cough, headaches and fever.

The seven corona viruses that affect humans can be categorized into two groups:
  1. Common Human Coronaviruses:- There four common human corona viruses are: 229E, NL63, OC43, HKU1. They usually cause mild to moderate cold. Those who contract these viruses are able to recover on their own immunity.
  2. Other Human Coronaviruses:- There other three common human corona viruses are: SARS-CoV, MERS-CoV and SARS-CoV-2(the novel corona virus). These coronaviruses pose more serious risks to human health. 

According to the World Health Organization (WHO), the first human case of Severe Acute Respiratory Syndrome (SARS) appeared in southern China in November 2002. SARS-CoV may have originated in bats and were transmitted to other animals before infecting humans. During the 2002-2003 epidemic, more than 8000 people in 26 countries around the world contracted SARS. There were 774 reported deaths.

Middle East Respiratory Syndrome (MERS)-CoV emerged in September 2012 in Saudi Arabia, although initial cases were later traced back to Jordan. Humans affected by MERS-CoV through contact with camels. The virus is also transmitted by coming into very close contact with an infected person. According to WHO, since 2012, 27 countries have reported more than 2400 MERS-CoV cases in which the majority of cases occurred in Saudi Arabia.

SARSCoV-2 (The Novel Corona Virus)
This novel corona virus appeared in Wuhan, China, in December 2019. After increase in pneumonia cases with no known cause the health department noticed it. It is a new strain of corona virus that has not been previously identified in humans. It’s dangerous because it’s transmitted easily from person-to-person, whether or not the person is exhibiting symptoms.

When the corona virus enters our body, it attacks the hemoglobin present in the red blood cells (RBC) of the blood. Hemoglobin acts as an oxygen-carrier in our body. When hemoglobin is affected by the corona virus, its oxygen carrying capacity gradually decreases. The corona virus also breaks the chain of hemoglobin formation in the body. Therefore, the amount of oxygen in the body is greatly reduced. This condition is called hypoxia. In this state, keeping the patient on ventilator also does not provide much benefit.

Corona literally means wreath (Crown-like shape).
The full name of Corona virus is SARS-CoV-2 (SARSSevere Acute Respiratory Syndrome-Corona Virus-2). This name has been given by the International Committee on Taxonomy of Viruses (London, UK). Here 2 used for spread of corona virus for the second time. Earlier Corona was spread in 1960s.

The World Health Organization (WHO; Geneva, Switzerland) has officially named the new Corona virus disease "CoViD-19".
Co-Corona, Vi-Virus, D-Disease, 19-year 2019 in which it came out.

Corona: The Origination of The Novel Coronavirus & Its Spread to Other Countries:-
It is believed that there was a live animal food market in Wuhan city of China. Corona virus started spreading from the bats of this market. First, it started spreading from bats to bats and then from bats to humans (the people of China drink supers of bats and a lot of insects etc.). Then this virus started spreading from humans to humans and became an infectious disease. Therefore, the city of Wuhan is being called the epicenter of the corona virus.

It is estimated that by the 20th or 23rd of January thousands of Chinese people were already affected by the new Corona virus. Despite this, during the Lunar New Year holiday, thousands of people from China went out of the world between 23rd to 30th January, such as Italy, Germany, US, UK, Thailand, Japan, Taiwan, Indonesia etc. 

All these people also knowingly and unknowingly took the corona virus with them and infected the residents there with the corona virus. After the outbreak of the corona virus epidemic in Wuhan city, foreigners living there also started returning to their country. Apart from this, when the corona virus spread in other countries, foreigners living there started returning to their country. All these people also helped in spreading the corona virus in a way.

Note:- Dr. Li Wen Liang, who first reported the corona virus and tried to notify via WE CHAT, was jailed and is now dead. Despite knowing how the disease is spreading and it is a serious issue, the Chinese government ignored Li Wen Liang's report.

The first case of the novel corona virus pandemic in India was reported on 30 January 2020 in Kerala. Also the first three cases in India were reported between 30 January and 3 February in Kerala. All three patients had returned from Wuhan, China — the epicentre of pandemic corona virus. All three patients recovered from the novel corona virus. Fresh cases continued to emerge every day since, with people bringing in the virus from Thailand, Iran and Oman.

The first death of coronavirus patient in India was reported in Kalaburagi, Karnataka on 10 March 2020. He was returned from Saudi Arabia on 29 February. According to officials, the patient had serious illnesses like high blood-pressure, diabetes, appendicitis and asthma.

Maharashtra, Odisha, Rajasthan, Bihar and Punjab had partially announced the lockdown before PM Shri Narendra Modi announced the complete lockdown.

Corona: Sports that postponed due to the novel corona virus
IPL-2020, Rio-Olympic, Tokyo-Olympic, French-Open Tennis Tournament etc.


There are 5 stages of corona virus from entering the life of a living being till its completion.

Stage 1-Incubation period:- For Corona virus this period is 10-15 days. Even after the virus reaches the body for so many days, it is not known. (Now you must have understood why people returned from abroad are being quarantined for 14 days.)

Stage 2-Identification Period:- Corona virus symptoms start appearing in the body after about 15 days. These viruses spread rapidly throughout the body of an infected person.

Stage 3-Spread Period:- By reaching this stage, the corona virus has spread in the human body in such a way that by touching it, the virus reaches another healthy person or place. Through the infected person these viruses start spreading on various thing.

Stage 4 and 5-Recovery Stage:- After reaching this stage, the data of the disease starts to decrease, if all people are quarantine. This whole stage lasts for about 3 to 4 months. (Now you must have understood why you are being asked to stay in your homes, if you will stay in the houses and keep cleanliness around you, then firstly you will avoid infection and when this disease is started by a new man If not, then this disease will be eradicated automatically in 1-2 months.

Corona virus warning sign

When an infected person meets some people it is possible that some of them have this infection and some do not. Because at that time, people whose immunity will be low, they can get this disease and those who will be immune, they will not get this disease. Nevertheless, the corona virus is present in these people. Therefore, they can also infect other healthy people. So stay at home, do not come in contact with unknown people, be healthy and keep others safe too.

Those who remain at a good level of immunity while treating corona, they recover as soon as possible. On the other hand, people who have diabetes, heart attack, blood pressure, breathing etc. have very little immunity. They get infected very quickly and they are more likely to die at the time of treatment. Therefore, special care should be taken in this terrible situation for the elderly and those suffering from the above disease. They should neither be allowed to leave the house nor meet anyone.

It is said that good is hidden in every corner of every evil. You can see this fact here too. The corona virus cause is lockdown all over India. There is no car running anywhere. This is not causing road accidents. The biggest thing is that pollution is not spreading. Talk about Delhi, the government here was proving to be a failure in working out air-pollution. But now the level of air pollution in Delhi has come down on its own. Working people (professionals), after a long time, spend their entire days with family, parents and children, which is a big thing in itself.

There is no known vaccine or medical treatment for COVID-19 yet.
