Essay on coronavirus in 1100 words
Coronaviruses are types of viruses that commonly affect the respiratory tract of mammals, including humans. They are associated with the common cold, pneumonia and severe acute respiratory syndrome (SARS) and can also affect the intestine.
A coronavirus was first isolated in birds in 1937 from an infectious bronchitis virus, which has the potential to seriously destroy poultry stocks.
These viruses are responsible for 15 to 30 percent of the common cold.
Over the past 70 years, scientists have found that coronaviruses can infect mice, rats, dogs, cats, turkeys, horses, pigs and cattle. Recently, authorities identified a coronavirus outbreak in China that has now reached other countries.
This MNT Knowledge Center article will focus on different types of human coronaviruses, their symptoms, how they are transmitted, and two particularly dangerous diseases that can be caused by coronaviruses: SARS and MERS.
What are coronaviruses?
Human coronavirues (HCoV) were first identified in the nose of common cold patients in the 1960s. The OC43 and 229E are responsible for a large proportion of the common cold with two human coronaviruses.
Coronaviruses were named after them with crown-like projections on their surfaces. “Corona” in Latin means “halo” or “crown”. Among humans, infection often occurs during the winter months as well as early spring. It is not uncommon for a person ill with a cold to be caused by coronovirus and to catch it again after about four months.
This is because coronovirus antibodies do not last very long. In addition, antibodies to one strain of coronavirus may be useless against other strains.
Facts on coronavirus
- There is no cure for the common cold.
- Coronovirus causes both SARS and mars.
- Coronavirus infects many different species.
- There are seven known human coronaviruses.
- SARS caused infections from China in 37 countries, killing 774 people.
Types of coronaviruses
There are currently seven recognized types of coronavirus that can infect humans:
- 229E (alpha coronavirus)
- NL63 (alpha coronavirus)
- OC43 (beta coronavirus)
- HKU1 (beta coronavirus)
Symptoms of coronaviruses
Cold or flu-like symptoms usually set in two to four days after a coronovirus infection, and they are usually mild. However, the symptoms vary from person to person, and some forms of the virus can be fatal.
- Sneeze
- a runny nose
- Fatigue
- cough
- In rare cases, fever
- Sore throat
- Severe asthma
Human coronaviruses cannot be easily cultivated in the laboratory unlike rhinoviruses, which is another cause of the common cold. This makes it difficult to detect the effect of coronaviruses on the national economy and public health.
There is no cure, so treatment involves taking care of yourself and over-the-counter (OTC) medication:
- Relax and avoid overexertion.
- Drink enough water.
- Avoid smoking and smoke areas.
- Take acetaminophen, ibuprofen or naproxen to reduce pain and fever.
- Use a clean humidifier or cool mist vaporizer.
The virus responsible can be diagnosed by taking a sample of respiratory fluids, such as mucus from the nose, or blood.
Transmission of coronovirus
There has not been much research on how the human coronovirus spreads from one person to another.
However, it is believed that viruses transmit using the fluid secreted from the respiratory system.
Coronavirus can be spread in the following ways:
- Coughing and sneezing without covering the mouth can spread virus-causing droplets into the air.
- Shaking or shaking hands with a person who has the virus can pass the virus from one person to another.
- Making contact with a surface or object that contains the virus and then touching your nose, eyes, or mouth.
- On rare occasions, coronovirus can spread through contact with feces.
2019- coronovirus
In 2019, the Centers for Disease Control and Prevention (CDC) began monitoring a new coronovirus outbreak. Authorities first identified the virus in Wuhan, China. He named it 2019 Novel Coronavirus (2019-nCov).
More than 1,000 people have contracted the virus in China. Health officials have identified many others worldwide with 2019-nCov, including many individuals in the United States. On January 31, 2020, the U.S. The World Health Organization (WHO) declared a public health emergency related to the virus 2019-nCov from one person to another.
Since then, 2019-nCov has started disintegration in 24 other countries. On February 10, 2020 in the United Kingdom, a clinic in Brighton temporarily closed after a member of staff contracted the virus. At the time of writing, he is one of eight people with the virus.
Some of the first people with 2019-nCov had connections to an animal and seafood market. It initially suggested that animals transmit viruses to humans. However, people with more recent diagnoses had no connection with or in contact with the market, suggesting that humans may pass the virus to each other.
Virus information is currently scarce. In the past, respiratory conditions that develop from coronaviruses, such as SARS and MERS, have spread through close contact.
However, while some viruses are highly infectious, it is less clear with coronavir how fast they will spread.
Symptoms vary from person to person with 2019-nCov infection. It can cause few or no symptoms. However, it can cause serious illness and can be fatal. Common symptoms include:
- fever
- breathlessness
- cough
It may take 2–14 days for a person to notice symptoms after infection.
There is currently no vaccine available for 2019-nCov. However, scientists have replicated the virus. This may allow early detection and treatment in those who have the virus but are yet to show symptoms.
What is SARS ?
The virus originated in southern China’s Guangdong province in November 2002 and eventually reached Hong Kong. From there, it rapidly spread around the world, infecting people in 37 countries.
SARS-CoV is unique. It can infect both the upper and lower respiratory tract and can also cause gastroenteritis.
SARS symptoms develop over the course of a week and begin with fever. At the onset of the condition, people develop flu-like symptoms, such as:
- Dry cough
- Chills
- Diarrhea
- breathlessness
- Pain
Severe acute respiratory syndrome (SARS) was a contagious disease caused by the SARS-CoV coronavirus.
What is MERS ?
MERS was first recognized in 2012 due to the MERS-CoV coronavirus. This serious respiratory disease was first reported in Saudi Arabia and has since spread to other countries. Virus us , And the largest outbreak outside the Arabian Peninsula occurred in South Korea in 2015. Symptoms include fever, shortness of breath, and cough. The disease is spread by close contact with people who have already been infected. However, all cases of MERS relate to individuals who have recently returned from a trip to the Arabian Peninsula.
