What is Coronavirus?

Coronavirus (CoV) is a large family of viruses that cause diseases, ranging from the common cold to more severe illnesses, such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). Most coronaviruses are harmless viruses.
Coronaviruses take their name from their crown-like halo
Coronavirus is a zoonotic virus, meaning that this virus is spread through animals and humans.
Quoted from WHO, the investigation shows that SARS-CoV is transmitted from ferrets to humans, while MERS-CoV is transmitted from dromedary camels to humans. There are also several other CoVs found in animals, but have not yet infected humans.

CoV in humans (HCoV) was first discovered in 1960 in the nose of patients affected by the common cold.

Two coronaviruses in humans, namely OC43 and 229E, are responsible for the occurrence of a portion of the common cold.

This virus is named based on a crown-like projection on its surface. "Corona" in Latin means "hello" or "crown".

The spread of coronavirus is the same as viruses that cause other flu, such as from coughing and sneezing, or from the touch of an infected person.

Almost all people have been infected with CoV at least once in their lifetime, usually occurring in children.

Coronavirus is a virus that generally appears in the fall and winter in the United States. However, everyone can get this virus at any time.

What are these types of viruses?

These types of viruses vary. The name is distinguished by the severity of the disease caused and how far it has spread.

Medical News Today said, currently there are six types of this virus that infect humans, namely:

  • 229E
  • NL63
  • 0C43
  • HKU1

A more rare type of coronavirus is MERS-CoV, which causes Middle East Respiratory Syndrome (MERS) and SARS-CoV, which causes Severe Acute Respiratory syndrome (SARS).

On January 7, 2020, as reported by the website of the world health agency, WHO, the Chinese government confirmed a new type of coronavirus that was endemic in late December.

The virus is a new type that is not similar to other coronaviruses. This virus is temporarily named after the 2019 coronavirus novel (2019-nCoV).

Radiation sickness

Overview Radiation sickness is damage to your body caused by a large dose of radiation often received over a short period of time (acute). The amount of radiation absorbed by the body — the absorbed dose — determines how sick you'll be. Radiation sickness is also called acute radiation syndrome or radiation poisoning. Radiation sickness is not caused by common imaging tests that use low-dose radiation, such as X-rays or CT scans. Although radiation sickness is serious and often fatal, it's rare. Since the atomic bombings of Hiroshima and Nagasaki, Japan, during World War II, most cases of radiation sickness have occurred after nuclear industrial accidents, such as the 1986 explosion and fire that damaged the nuclear power plant at Chernobyl, Ukraine. Symptoms The severity of signs and symptoms of radiation sickness depends on how much radiation you've absorbed. How much you absorb depends on the strength of the radiated energy, the time of your exposures, and the distance b

Acute liver failure

Overview Acute liver failure is loss of liver function that occurs rapidly — in days or weeks — usually in a person who has no preexisting liver disease. It's most commonly caused by a hepatitis virus or drugs, such as acetaminophen. Acute liver failure is less common than chronic liver failure, which develops more slowly. Acute liver failure, also known as fulminant hepatic failure, can cause serious complications, including excessive bleeding and increasing pressure in the brain. It's a medical emergency that requires hospitalization. Depending on the cause, acute liver failure can sometimes be reversed with treatment. In many situations, though, a liver transplant may be the only cure. Symptoms Signs and symptoms of acute liver failure may include: Yellowing of your skin and eyeballs (jaundice) Pain in your upper right abdomen Abdominal swelling (ascites) Nausea Vomiting A general sense of feeling unwell (malaise) Disorientation or confusion Sleepiness Breath may have a must
