Coronavirus Causes, Symptoms and Prevention

 

Corona pandemic has shocked the world and everyone is badly affected by the outbreak of the virus. The virus which started spreading from Wuhan, China has reached almost all places around the globe. Countries are still actively battling the deadly virus but societies and industries are now also looking to rebuild and re-emerge from the crisis. Over 15,383,845 cases have been confirmed and almost 630,365 deaths recorded till now. The number of cases “recovering” from symptoms over 9,356,375. The remainder is still under observation or quarantine. Here in this, we can discuss the coronavirus, its symptoms and treatment.

What is coronavirus?

Coronaviruses are a large family of viruses which may cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

What is COVID-19?

COVID-19 is an infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).

Corona Virus

It spreads the same way other coronaviruses do, mainly through person-to-person contact. Infections range from mild to deadly. SARS-CoV-2 is one of seven types of coronavirus, including the ones that cause severe diseases like the Middle East respiratory syndrome (MERS) and sudden acute respiratory syndrome (SARS). The other coronaviruses cause most of the colds that affect us during the year but aren’t a serious threat for otherwise healthy people.

Causes of Coronavirus

Humans first get a coronavirus from contact with animals. Then, it can spread from human to human. Health officials do not know what animal caused COVID-19.

The COVID-19 virus can be spread through contact with certain bodily fluids, such as droplets in a cough. It might also be caused by touching something an infected person has touched and then touching your hand to your mouth, nose, or eyes. The recent outbreak began in Wuhan, a city in the Hubei province of China. Reports of the first COVID-19 cases started in December 2019.

Coronaviruses are common in certain species of animals, such as cattle and camels. Although the transmission of coronaviruses from animals to humans is rare, this new strain likely came from bats, though one study suggests pangolins may be the origin.
Some reports trace the earliest cases back to a seafood and animal market in Wuhan. It may have been from here that SARS-CoV-2 started to spread to humans.

How does it spread?

When people with COVID-19 breathe out or cough, they expel tiny droplets that contain the virus. These droplets can enter the mouth or nose of someone without the virus, causing an infection to occur. The most common way that this illness spreads is through close contact with someone who has the infection. Close contact is within around 6 feet.
The disease is most contagious when a person’s symptoms are at their peak. However, it is possible for someone without symptoms to spread the virus. A new study suggests that 10% of infections are from people exhibiting no symptoms.

Symptoms of coronavirus

Doctors are learning new things about this virus every day. So far, we know that COVID-19 may not initially cause any symptoms for some people. Let’s list out the symptoms here.

  • Fever
  • Coughing
  • Shortness of breath
  • Trouble breathing
  • Fatigue
  • Chills, sometimes with shaking
  • Body aches
  • Headache
  • Sore throat
  • Loss of smell or taste
  • Nausea
  • Diarrhoea

The severity of COVID-19 symptoms can range from very mild to severe. Some people may have only a few symptoms, and some people may have no symptoms at all. Some people may experience worsened symptoms, such as worsened shortness of breath and pneumonia, about a week after symptoms start.

How coronavirus could be diagnosed?

COVID-19 can be diagnosed similarly to other conditions caused by viral infections: using a blood, saliva, or tissue sample. However, most tests use a cotton swab to retrieve a sample from the inside of your nostrils. Using the cotton swab provided, people will be able to collect a nasal sample and mail it to a designated laboratory for testing. The emergency-use authorization specifies that the test kit is authorized for use by people whom healthcare professionals have identified as having suspected COVID-19. Talk to your doctor right away if you think you have COVID-19 or you notice symptoms.

What are the preventive measures?

Till now there is no treatment for coronavirus, but we have to keep in mind certain things to be safe.

  • Avoid large events and mass gatherings.
  • Avoid close contact (within about 6 feet, or 2 meters) with anyone who is sick or has symptoms.
  • Stay home as much as possible and keep distance between yourself and others
  • Wash your hands often with sanitizer or soap
  • Cover your face with a cloth face mask in public spaces
  • Avoid touching your eyes, nose and mouth.
  • Clean and disinfect high-touch surfaces, such as doorknobs, light switches, electronics and counters, daily.
  • Stay home from work, school and public areas if you’re sick unless you’re going to get medical care.
  • Avoid public transportation, taxis and ride-sharing if you’re sick.

Treatment for Coronavirus

There is currently no vaccine or treatment for COVID-19. Symptoms of a coronavirus usually go away on their own. If symptoms feel worse than a common cold, contact your doctor. He or she may prescribe pain or fever medication. While some western, traditional or home remedies may provide comfort and alleviate symptoms of mild COVID-19, there are no medicines that have been shown to prevent or cure the disease. WHO does not recommend self-medication with any medicines, including antibiotics, as a prevention or cure for COVID-19

Conclusion

When possible, avoid contact with others when you are sick. It is also possible to spread the virus if you don’t have symptoms. Self-isolation is an important measure taken by those who have COVID-19 symptoms to avoid infecting others in the community, including family members. If you have any symptoms kindly contact the doctor. Contact Medisys Hospitals for more details
