What is Coronavirus (COVID-19)? How it spread, diagnose & treated?

What is Coronavirus (COVID-19)? How it spread, diagnose & treated? A new virus called Acute Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been identified as the cause of the outbreak of the disease in China in 2019. This disease is known as coronavirus disease 2019 (COVID-19).

What is COVID-19?

Coronavirus disease (COVID-19) is a newly discovered coronavirus infection.

Most of the people that are infected by the COVID-19 have mild to respiratory illness and recover without the need for any special treatment. Older people, and those with medical problems such as cardiovascular diseases, diabetes, chronic respiratory disease, and cancer, are at increased risk of serious illness.



The good way to prevent and slow the rate of transmission is to be well aware about the COVID-19 virus, the causes of disease, and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol-based rub frequently and without touching your face.

The infected person coughs or sneezes when the COVID-19 virus is released mainly from saliva or through the nose, so it is important that you follow the respiratory etiquette (for example, by coughing with a curved elbow).

There are no specific treatments or vaccines for COVID-19 at this time. However, there are a lot of clinical trials that evaluate potential therapies. WHO will continue to provide updated information as soon as clinical research becomes available.

Covid-19 cases have been reported in a growing number of countries, including the US WHO announcing the global pandemic in March 2020. WHO and the US CDC are monitoring the situation and posting updates, prevention and treatment recommendations on their websites.

How does COVID-19 spread?

The new coronavirus spreads from person to person in close contact. It spreads through respiratory droplets when someone is infected with a cough or sneeze. Not sure how infectious the virus is. COVID-19 is found in people around the world and is considered a pandemic.

The spread of this new coronavirus is being monitored by the Centers for Disease Control (CDC), the World Health Organization (WHO) and health agencies worldwide such as Johns Hopkins.

COVID19 spread


How has this new coronavirus spread to humans?

In December 2019, COVID-19 appeared in the city of Wuhan, China. Although health officials are still searching for the exact source of this new coronavirus, early hypotheses suggest it may be linked to a seafood market in Wuhan, China. Some who have visited the market have developed viral pneumonia caused by the new coronavirus. A study on January 25, 2020, stated that the person with the first reported case fell ill on December 1, 2019, and had nothing to do with the seafood market. Investigations into how the virus originated and spread are ongoing.

What is the incubation period for COVID-19?

Symptoms appear to be present in people within 14 days of being exposed to the virus.

What are the symptoms of COVID-19?

Its symptoms include:

  • Cough
  • Fever
  • Shortness of breath

COVID-19 symptoms

In rare cases, COVID-19 can lead to serious respiratory problems, kidney failure, or death.

If you have a fever or respiratory problems such as cough or wheezing, call your doctor or health care provider and explain your symptoms on the phone before going to the doctor’s office, emergency care facility, or emergency room. Here are suggestions if you feel sick and you may have COVID-19.

If you have a medical emergency such as acute respiratory distress, call 911 and let them know about your symptoms.


How is COVID-19 diagnosed?

Diagnosis can be difficult with physical examination alone because mild cases of COVID-19 can look like flu or a bad cold. Laboratory testing can confirm the diagnosis. Learn more about the COVID-19 test.

How is COVID-19 treated?

Yet, there is no specific and proper treatment for the virus. Persons suffering from COVID-19 should be treated with supportive measures: relieving symptoms. In severe cases, there may be additional options for treatment, including research medications and treatment options.

Does COVID-19 cause death?

As of March 30, 2020, 34,686 deaths were attributable to COVID-19. However, 154,673 people recovered from the illness. This information comes from the Coronavirus COVID-19 Global Case Map developed by the Johns Hopkins Center for Systems Science and Engineering.

What is a coronavirus?

These are the family of viruses that cause disease in animals. Seven, including the new virus, are jumping to humans, but most often cause colds.

Covid-19 is closely associated with the acute respiratory syndrome (SARS), which spread worldwide from 2002 to 2003. The virus infected 8,000 people and killed 800 people, but it soon ran out, because most of those infected were very sick and easy to control.

Another coronavirus in the Middle East Respiratory Syndrome (MERS), a rare occurrence since it first emerged in 2012 – about 2,500 cases and nearly 900 deaths.

Kovid-19 differs from these two other coronaviruses in that the spectrum of the disease is widespread, with 80 percent of cases leading to mild infection. Many people carry the disease and may not exhibit symptoms, which can make it more difficult to control.

So far, 20 percent of Covid-19 cases have been classified as “serious” and the current mortality rate varies between 0.7 percent and 3.4 percent depending on location and, most importantly, access to good hospital care.

Scientists in China believe that Kovid-19 has transformed into two strains, one more aggressive than the other, making the vaccine more difficult to develop.


How did the outbreak begin?

The source of the coronavirus is believed to be the “wet market” in Wuhan, which sells dead and live animals, including fish and birds.

In such markets, viruses are at risk of jumping from animal to human, because hygiene standards are difficult to maintain when live animals are kept and butchered. Generally, they are densely packed, spreading from species to species.

its original host is the bats. Bats are not sold in the market of Wuhan but may be infected with live chickens or any other animals that sell in the market.

Bats host a wide variety of zoonotic viruses, including Ebola, HIV and rabies.

What are the symptoms of coronavirus?

Initial symptoms include fever, dry cough, fatigue and feeling unwell. Other symptoms include loss of taste and smell and stomach problems. To read the full list of symptoms and treatment of coronavirus, click here.

How do you protect yourself from this coronavirus?

Maintaining good hygiene, respiratory etiquette, and social distance is critical. Read more about ways to protect yourself.

About Coronaviruses

  • Coronaviruses are common in various animals. Rarely, animal coronavirus infects humans.
  • There are many types of coronaviruses. Some of them cause colds or other mild respiratory (nose, throat, lung) illnesses.
  • Other coronaviruses cause more serious diseases, including acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS).
  • Coronaviruses are named for their appearance: under the microscope, the viruses appear to be covered with angular structures such as the corona or crown.

Is this coronavirus different to SARS?

SARS is a severe acute respiratory syndrome. In 2003, the spread of SARS began in China and spread to other countries before ending in 2004. The virus that causes COVID-19 is similar to that caused by the 2003 SARS outbreak: both are types of coronaviruses. Not much is known yet, but COVID-19 is spreading faster than 2003 SARS and may cause less serious illness.

Is coronavirus in the UK?

In the UK, 22,141 people have tested positive for the virus so far.

An elderly man with health problems became the first person in Britain to suffer from the disease, the Royal Berkshire NHS Trust confirmed on March 5. A total of 1,408 people have died since then.

The police have been given unprecedented powers to detain those at risk of coronavirus, for fear that two GPs might send the virus to patients.

Boris Johnson urged everyone in the UK to be at home now, as the largest restriction on civil liberties was implemented.

Is there a cure for coronavirus?

Although doctors are already testing drugs for viruses such as Ebola, malaria and HIV, there is no specific treatment. Although the initial results seem promising, doctors are not sure whether the drugs are effective until the completion of complete clinical trials.

The work on developing the vaccine is accelerating, but it is unlikely to be available until next year.

Is the coronavirus in the air?

There is some debate as to whether the disease is in the air – there is no evidence yet, but it may change. Viruses in the air can last longer than those spread by droplets and can also spread in air conditioning and ventilation systems.

The current suggestion is that the disease can only spread between close contacts – spending more than 15 minutes on an infected person’s two meters.

Who started the coronavirus?

There are various crazy conspiracy theories that the virus has somehow escaped from a Chinese lab by accident or design. However, it is taxonomically unrealistic and scientists who study its genetic code have linked it to bats. It probably jumped at another animal and sent it to humans.

The number of diseases spreading from animals to humans is increasing and teams of virus hunters are tracking them.

Should I Cancel My Travel Plans? After COVID-19 disease?

On March 17, the Foreign Office advised British citizens to stay away from unnecessary overseas travel for at least 30 days – and no one knows if this will be extended beyond that period.

However, many countries have instituted travel bans, preventing Britons and foreign nationals from entering. While Donald Trump has announced a ban on US visitors from Europe and the UK, many other countries will not allow access to British citizens.

The Telegraph Travel Team has in-depth advice on affected countries and your rights if you cancel your trip.

How serious is COVID-19 disease?

According to data from the first forty four thousand cases released by Chinese authorities, 80% of cases are mild.

In about 14 %of cases, the virus causes serious illness such as pneumonia and shortness of breath. It is critical in five percent of patients, leading to respiratory failure, septic shock, and multiple organ failure.

According to the WHO, the death rate in Wuhan is two to four percent, compared to 0.7 percent in China.

Mortality rates vary greatly across the globe, and there are multiple reasons: Experts believe that the death toll may be related to the age of the affected person and the state of the health care service in a country.


Can COVID-19 be prevented or treated?

No vaccine is currently available for coronavirus disease 2019 (COVID-19). Antiviral drugs are not recommended for the treatment of COVID-19. Treatment is to relieve symptoms.

What can I do to avoid getting sick?

WHO and CDC recommend the following precautions to prevent COVID-19:

  • Stay away from big events and mass gatherings.
