Essay on Coronavirus (COVID19) History, Symptoms, Causes, Prevention

In this article, we have an Essay on Coronavirus (COVID19) contain all information like History, Symptoms, Causes, Preventive measures, given by WHO and Health organizations.

Introduction on Coronavirus (COVID19)

Coronavirus is an infection that causes regular colds, intense respiratory disorders (SARS), and Middle East respiratory disorder (MERS). In 2019, coronavirus was recognized for the spread of an infection that began in China. The virus is currently known as Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The sickness that causes it is called Coronavirus Disease 2019 (COVID-19).

The World Health Organization (WHO) is monitoring the growing number of COVID-19 cases, status, and postings in countries including the US Center for Disease Control and Prevention (CDC), a US public health group. Updates on their websites. The WHO announced a worldwide pandemic in March 2020. These groups have also issued recommendations for disease prevention and treatment.

History of Coronavirus (COVID19)

It appeared on December 19, 2019, in the city of Wuhan, Kovid-China. Although health officials are yet to determine the exact source of this new coronavirus, the earliest hypotheses are likely to be related to a seafood market in Wuhan, China.

A few people who visit the market have created viral pneumonia due to the new coronavirus. A study that appeared on January 25, 2020, reported that people with previously reported cases fell ill on December 1, 2019, and had nothing to do with the sea-food market. How the infection began and spread is under scrutiny?

Coronavirus Symptoms (COVID-19)

Reported illnesses range from people with mild symptoms to severe disease and death.

Symptoms may include:

  1. Fever
  2. Cough
  3. Shortness of breath

Specific features:

  • COVID-19 usually causes flu-like symptoms, including fever and cough.
  • It begins with fever, trailed by the dry hack.
  • A week later, it may cause respiratory failure, with about 20% of patients requiring hospital treatment.
  • In particular, COVID-19 disease once in a while causes sickness, sniffling, or sore throat (these indications are available in just 5% of patients). Sore throat, wheezing, and runny nose are regularly side effects of chills.

80% of cases are gentle 

  • In light of affirmed, suspected, and asymptomatic instances of 72,314 instances of COVID-19 cases in China as of February 11, the Chinese CCDC discharged on February 17 a paper distributed in the Chinese Journal of Epidemiology: 80.9% of infections are mild (with flu-like symptoms) and can be cured at home.
  • 8-13.8% are severe, developing severe diseases such as pneumonia and shortness of breath.
  • 4.7% are critical and may include respiratory failure, septic shock, and multi-organ failure.
  • In cases reported, 2% of the virus is fatal.
  • The danger kicks the bucket increments as you become more established.
  • Relatively few cases are seen in children.

Pre-existing conditions

Pre-existing diseases that pose a higher risk to patients include:

  1. Heart disease
  2. Diabetes
  3. Interminable respiratory sickness
  4. Blood pressure

After getting infected, some healthy people begin to develop a severe form of pneumonia. 

Causes of Coronavirus outbreak

It is not clear how contagious the new coronavirus is. It seems to be spreading from one person to another among those closely related. It covers and increases via respiratory micro drops when the virus coughs or sneezes.

It also spreads if a person touches the surface of a virus and touches its mouth, nose, or eyes.

1. Spread from person to person

It is accepted that the infection spreads fundamentally from individual to individual between individuals in close contact with one another (inside around 6 feet). Shortness of breath occurs when an infected person coughs or sneezes.

Imagine sitting next to people with SARS-CoV-2 infection on a bus or in a room. Suddenly, this person is sneezing or coughing.

If they do not cover your mouth and nose, they can spray with breath drops from your nose or mouth. The spots on you may contain the virus.

Maybe you meet someone infected with the virus, and they touch their mouth or nose with their hand. When that person moves your hand, they transfer some viruses to your hand. F When you first contact your mouth or nose without washing your hands, you may accidentally inject the virus into your body.

These drops can enter the mouth or nose of individuals who live close by or in the lungs.

• People think of it as an epidemic when they are very sick (very sick).

Symptoms – Some symptoms are possible before people show signs; There have been reports of this happening with the new coronavirus, but it is believed to be the primary method for spreading the virus.

2. Spread by contact with sullied surfaces or items

An individual is probably going to get a COVID-19 by contacting a surface or article, recognizing the infection on it, and afterward contacting their mouth, nose, or their eyes; however, this is the principle infection. This strategy isn’t viewed as an episode. 

Impacts on the human body 

Researchers have figured out how the new infections influence cells and how they influence organs past the lungs. As governments take extraordinary measures to limit the incidence and spread of coronavirus infection worldwide, there is still much confusion about what correctly the virus is doing in people’s bodies.

Symptoms – fever, cough, wheezing – indicate any disease from flu to cold. Because of this new coronavirus, so far, medical professionals and researchers are aware of the progress of the infection – and they are still unaware of it.

1. Breathing – Systemic Problems

When copies of the virus multiply, they exit and infect neighboring cells. Symptoms often begin with a sore throat & dry cough in the throat.

Dr. Scheffner then said that the virus “gradually crawls the bronchial tubes” when this infection or a virus enters the lungs, their mucous membrane becomes inflamed. It disrupts the alveoli or lungs, and they must work to maintain oxygen supply to the blood circulating throughout the body and to remove carbon dioxide from the blood. 

2. Fever and cough

Hirsch says it takes two to 14 days for a person to develop symptoms after being exposed to the virus. The average is five days.

Inside the body, it begins to infect epithelial cells in the epithelial layer. The protein located at the receptors of the virus binds the receptors of the host cell and enters the cell. Within the host cell, the replication begins until the virus kills the cell.

It first occurs in the upper respiratory tract, which includes the nose, mouth, larynx, and bronchi.

The patient begins to experience a mild version of the symptoms: dry cough, shortness of breath, fever, and headache, and muscle aches, and fatigue, equivalent to flu.

3. Pneumonia and autoimmune disease

The WHO reported last month that 80% of patients have mild to moderate infections. One case of “mild” COVID-19 has more fever and cough than seasonal flu but does not require hospitalization.

Hirsch notes that the body’s immune response to those cases can include the virus in the upper respiratory tract. Smaller patients are more immunosuppressed than older patients.

In severe cases, 13.8% and 6.1% of critical cases enter the windpipe and the lower respiratory tract of the virus, so it prefers to grow.

The virus continues to move into the pipe and slung, says Dr. Hopkins Medicine’s infectious pathologist. According to Raphael Whiskey, it can cause respiratory problems such as bronchitis and pneumonia.

Preventive measures 

Follow the rules to help shield SARS-CoV-2 from getting, conveying, and voyaging. 

1. Wash your hands as often as possible and cautiously 

Utilize lukewarm water and cleanser and rub your hands for at any rate 20 seconds. Work on your wrists, between your fingers, and the base of your fingernails. You can likewise utilize antibacterial and antiviral cleanser. Utilize a hand sanitizer when you can’t wash your hands appropriately. Update your hands a few times each day, particularly after contacting anything, including your telephone or PC. 

2. Abstain from touching your face 

SARS-CoV-2 can last as long as 72 hours on harsh surfaces. If you contact a surface like a door handle, a gas siphon handle, or your wireless, the infection gets in your grasp. Abstain from contacting any piece of your face or head, including your mouth or nose. Likewise, abstain from gnawing your nail allows SARS-CoV-2 to get into your body with your hands. 

3. Stop shaking hands and grasping people – until further notice 

Likewise, abstain from contacting others. Skin-to-skin contact transmits SARS-CoV-2 starting with one individual then onto the next.

4. Do not share personal belongings

Do not share personal items such as a phone, makeup kit, or comb. It is also crucial not to share food utensils and straws. Teach children to use recyclable cups, straws, and other recipes for their use.

5. Put Elbow or cloth on your mouth and nose when you hack and wheeze

SARS-CoV-2 is found in large amounts in the nose and mouth. It means that when you cough or sneeze, air spots can be taken to other people. It descends to rough surfaces and stays there for three days.

Use tissue or wheeze on your elbow to keep your hands as spotless as could be expected under the circumstances. Wash your hands carefully, despite sneezing or coughing.

6. Clean and disinfect surfaces

Use alcohol-based disinfectants to clean hard surfaces such as countertops, door handles, furniture, and toys in your homes. You use your phone, laptop, and anything else several times a day.

Disinfectant areas after bringing groceries or packages to your home – Use white vinegar or hydrogen peroxide solution for routine cleaning between disinfectant surfaces.

7. Pay attention to social contrast 

If you convey the SARS-CoV-2 infection, it will locate a lot of your spit. It can happen in any event, when you have no side effects. Social distance means staying at home and working remotely when possible. If you need to go out for what you need, keep it 6 feet away from other people. You can spread the virus by talking to someone close to you.

8. Do not collect in groups

Being in the group or gathering means you can get in touch with someone. It includes avoiding all religious places of worship because you have to sit or stand close to another community. It also involves building a community in parks or beaches.

9. Abstain from eating or drinking out in the open spots

At present, one shouldn’t go out to eat. It means you should avoid restaurants, coffee shops, bars, and other eateries. The infection is transmitted through nourishment, utensils, dishes, and cups. It is additionally noticeable all around from others at the scene.

You can still get delivery or takeaway meals. Choose foods that cook well and serve hot. High temperature (at least 132 ° F / 56 ° C, according to a recent, yet peer-reviewed laboratory study) helps kill coronavirus. It means it’s best to avoid all foods from the restaurant’s soft menus and buffets and open salad bars.

10. Wash fresh grocery properly

Soak raw, whole fruits, and vegetables in food grade hydrogen peroxide or white vinegar solution. Allow them to dry before placing them in your fridge and cupboard. You can also use a vegetable antibacterial wash to clean it. Wash your hands when taking care of crisp produce.

11. Self-incarceration if ill

Call your doctor if you have any symptoms. Stay at home until recovering. Avoid sitting, sleeping, or eating with your loved ones, even while staying in the same house.

Wash your hands with the mask as much as possible. If you need immediate medical attention, wear a mask, and tell them that you have COVID-19.

12. Lockdown

Lockdown is an emergency protocol that prevents people from leaving a given area. A complete lockdown means you have to be absent and do not exit or enter the building or given space.

This scenario will allow the public to continue to serve the people with the necessary supplies, grocery stores, pharmacies, and banks. All unnecessary activities will be closed for the entire duration.

The Conclusion

There is no doubt that this is a global catastrophe for all of us. The whole world is defeating it with all its efforts. Many countries shut down their countries and order the citizen to stay inside the house. What we all have to say to the government, we must take action. We hope that our scientists will find a vaccine for this and that our world will win from this significant outbreak.
