Do you know the Corona-virus definition? what is coronavirus? What are the types of Corona-virus? Why Corona-virus is dangerous? What is COVID-19? In this article, we want to discuss such issues.
COVID-19 is a common dangerous disease caused by the Corona-virus family, belongs to an extended family of viruses that can infect both animals and humans. The prevalence of this virus is fast but the mortality is low.
What are the types of Corona-virus?
There are many different types of Corona-virus with different prevalence and mortality rates. The most well-known types of Corona-virus in this family are(1):
- 229E (alpha Corona-virus)
- NL63 (alpha Corona-virus)
- OC43 (beta Corona-virus)
- HKU1 (beta Corona-virus)
- Novel Corona-virus disease nCOV-2019 (n-COVID-19)
The virus from the Corona-virus family, known as the “SARS virus (SARS-CoV)” causes a serious disease called “Severe Acute Respiratory Syndrome” or SARS. It was first reported in Guangdong, China, in November 2002, and then spreads to Hong Kong, then expanded across the world.
In 2012, another virus from the Corona-virus family which was able to cause a severe respiratory disease called the “Middle East Respiratory Syndrome” or MERS prevalence(2). The first case observed in Saudi Arabia, and other cases reported in France, Germany, Jordan, Qatar, Tunisia, United Arab Emirates, and the United Kingdom in 2013. Besides, almost two-thirds of the MERS patients have died.
3- Coronavirus type n-CoVID 2019
What is coronavirus new properties and effects? The new virus named by the World Health Organization (WHO), Corona-virus n-CoV2019 virus. The first time the virus found in people connected to the Chinese seafood market in Wuhan in China. Also, the first report of the virus registered on December 31, 2019, at the World Health Organization.
Which types of Coronavirus patients exist?
The Novel Corona-virus patients divide into 3 groups. COVID-19 severity was classified as mild, moderate, severe, or critical. Patients in the severe and critical subgroups were deemed to have severe pneumonia, whereas those in the mild and moderate subgroups were deemed to have non-severe pneumonia(3). Mild symptoms include low-degree fever, dry cough, tiredness, restlessness, or throat pain without warning symptoms such as difficulty breathing or shortness of breath. This group can treat by health care and rest at home, according to the World Health Organization’s recommendation.
The severe symptoms include high fever, an increase in difficult breathing, throat sputum or Throat bleeding, gastrointestinal symptoms such as nausea, vomiting, and diarrhea with no change in mood such as confusion or tiredness that should be referred to medical centers immediately(4). Fortunately, based on statistics 80% of Corona-virus patients had mild symptoms and were recovered.

Does the Corona-virus spread through the air?
The Corona-virus is transmitted from tiny respiratory droplets from someone’s coughing, sneezing, or even talking. But these droplets do not remain in the air but they remain on the environment. But some reports mention that this virus may spread in the air. The measles virus, Unlike the Corona-virus, is suspended in the air for two hours after sneezing and coughing.
What’s the meaning of social distance and why it’s necessary?
Social distance or physical distance means to avoid having close contact with people, do not go to crowded places, do not meet others, and keep a safe distance in necessary cases. In fact, Social distance can reduce the chance of infection.
Do recovered COVID-19 patients reinfect?
WHO researchers Announced that recovered Corona-virus patients may get the Corona-virus again,.The Director-General of the World Health Organization has already said they have no definitive answer to this question and are investigating it. no study has evaluated whether the presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection by this virus in humans.
Is there any vaccine for COVID-19?
Weak and safe viruses that injected into the human body, to protect the body from the viruses, are called the vaccine. The white blood cells (WBCs) identify these weak viruses and destroy them and make a substance called antibodies. When active viruses from that type recognize again the body WBCs destroys them quickly. Despite many efforts of scientists so far, the definitive vaccine has not found for this mysterious disease. There is also no definitive therapy or treatment for COVID-19. Therefore, the only way is to prevent and Observance of health principles and try to break the coronavirus chain of transmission. Also, boost the immune system to tackle with the COVID-19
Is there any Corona-virus treatment?
While some chemical, traditional or herbal medicines may relieve the Corona-virus symptoms and be effective for Corona-virus treatment, there is no evidence of the definitive Corona-virus treatment and COVID-19. WHO has declared that no vaccine has been detected for the virus, and WHO announced that no vaccine has been developed so far and researchers are continuously trying for it.
What are the medications to treat COVID-19?
- Hydroxychloroquine: May reduces the inflammation by affecting the Immune system and limits the damages caused by disease. hydroxychloroquine may reduce the production of various pro-inflammatory cytokines, such as IL-1, IL-6, interferon-α, and tumor necrosis factor, which are involved in the cytokine storm. These immunomodulatory effects may synergize their antiviral effects in the treatment of COVID-19(6).
- IVIG: May boost the Immune system and increases antibodies(7).
- KALETRA: Is an antiviral medicine for the treatment or prevention of different viruses.
- Ribavirin: Is an antiviral medicine for the treatment of severe respiratory infections.
- Sofosbuvir: Is an antiviral medicine uses to treat hepatitis C.
- Daclatasvir: like Sofosbuvir is an antiviral medicine and may treat hepatitis C.
- Atazanavir: Is an antiretroviral medicine uses to treat human immunosuppressive viruses such as HIV.
- Umifenovir: Used to treat viral infections such as influenza.
- Oseltamivir: Used to treat influenza A and B.
- Azithromycin: Is an antibiotic medicine for the treatment of bacterial infections such as strep throat.
- Dexamethasone: Used to relieve inflammation.
The effect of these drugs is not definitive for Corona-virus treatment and most of them are under experimental uses. However, in some cases have been partly effective, based on reports. But these medications are not approved by the WHO, and definitely need to avoid using without a doctor’s prescription. Arbitrary consumption can have very dangerous consequences.
