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).

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? 

what is coronavirus

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

What are the medications to treat COVID-19?

  1. 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).
  2. IVIG: May boost the Immune system and increases antibodies(7).
  3. KALETRA: Is an antiviral medicine for the treatment or prevention of different viruses.
  4. Ribavirin: Is an antiviral medicine for the treatment of severe respiratory infections.
  5. Sofosbuvir: Is an antiviral medicine uses to treat hepatitis C.
  6. Daclatasvir: like Sofosbuvir is an antiviral medicine and may treat hepatitis C.
  7. Atazanavir: Is an antiretroviral medicine uses to treat human immunosuppressive viruses such as HIV.
  8. Umifenovir: Used to treat viral infections such as influenza.
  9. Oseltamivir: Used to treat influenza A and B.
  10. Azithromycin: Is an antibiotic medicine for the treatment of bacterial infections such as strep throat.
  11. Dexamethasone: Used to relieve inflammation.
