In this article, we will study the proper definition, Causes, mode of transmission SARS CoV-2, where it comes from, the area where it is spread, incubation period, signs and symptoms, nature of this virus, treatment including the vaccines, and prevention.

SARS - Diagnosis, Treatment, Symptoms & Causes | Corona VIRUS and SARS CoV | Transmission of SARS CoV
SARS Explained


The full form of SARS is SEVERE ACUTE RESPIRATORY SYNDROME. From respiratory word we all can guess that this virus is also affects our respiratory system. This disease is spread from a virus named SARS CoV ( severe acute respiratory syndrome coronavirus). This is a single standard RNA virus. SARS CoV coronavirus began in China in 2003 and within a few months, this virus spread the other 26 countries, and about 8000 people affected. 


Causes of SARS

The SARS is a Zoonotic disease that means, like coronavirus, SARS is also spread from animal viruses. severe acute respiratory syndrome coronavirus and coronavirus belongs to the same class of viruses. The major animals are bats, perhaps, and cats firstly affected. Several animals take this virus without becoming the sick cause they have strong immunity, after that, it reached on to the human, In previous years no other virus seems to be very harmful to humans. But this virus is deadly. 

 

Routes of Transmission of SARS CoV 

It can be transmitted with a direct connection, droplets, bloodborne, mother to child, animal to human, and fomite. some of the infected people never develop symptoms like animals. 

Respiratory droplet transmission can occur when a healthy person is in close contact with an infected person who has some signs like sneezing and coughing. in this circumstance, the respiratory droplets that have the virus reach the healthy person.  


Airborne Transmission

This transmission can occur during medical procedures, that produce aerosols. It is defined as the spread of an infectious agent caused by the distribution of droplets that remain infectious when suspended in air over a long time. these droplets come in the contact with one person to another. This virus can survive for a different period on various objects. Aerosoles transmission can also possible in public places like grounds, parks, restaurants, and gyms, etc.


Fomite transmission

This transmission occurs when we use things like cloths, brush, comb, thermometer, and stethoscope of an infected person. fomite transmission is also called indirect transmission. This virus can alive for some time on the used things of the infected person. This transmission occurs indirectly through when we are touching surfaces objects contaminated with the patient of SARS CoV and supported by the touching nose, eyes, and mouth. it is also occurred by skin to skin contact (handshake or hug).

SARS can survive for hours on general surfaces outside the human body and up to 4 hours on human waste. on the plastic, it can survive for 24 hours at room temperature. 

Incubation period - The incubation time has been estimated 5 to 7 days and generally 3 to 4 days.


Signs and Symptoms of SARS CoV

Muscle ache, headache, fever, lower respiratory tract illness like cough, shortness of breath, sneezing, difficulty in breathing, radiographic evidence of lungs infiltrates consistent with acute respiratory distress syndrome. In some cases, there is prompt deterioration with low oxygen saturation requiring ventilatory support.

 

Diagnosis of SARS

The Diagnostic tests are required for lab verification of SARS - 

  • Conventional reverse transcriptase PCR and real -time transcriptase PCR.
  • Enzyme-linked immunosorbent assay and immunofluorescent assay.


Treatment of SARS  

There is no permanent treatment for SARS. SARS patients need intensive maintenance. 


MEDICATIONS or AGENTS which are used to treat SARS


  1. Ribavirin ( 400-600 mg/d and 4g/d)
  2. Lopinavir/ritonavir(400mg/100mg)
  3. Intravenous immunoglobulin
  4. interferon type 1

 

How can we prevent SARS?

There is no vaccine for SARS, the preventive measures for this virus includes-


  1. Immediate identification of persons with SARS, there actions, and touches.
  2. SARS sufferers admitted ineffective isolation wards.
  3. Simple hygiene is also really important such as hand washing after touching an infected person, use well-fitted masks.
  4. take medicines that boost your immunity.
  5. Proper protection of therapeutic staff treating SARS patients.
  6. Appropriate and accurate reporting and sharing updates with other authorities and governments.

 

SIMILARITIES in Corona VIRUS and SARS CoV

They both are communicable (person to person) and Zoonotic ( animal to human) diseases. There symptoms like coughing, sneezing, other respiratory complications. Both SARS and the coronavirus can survive outside the human body over a long period. We can prevent these with the same methods such as appropriate sensitization, wearing masks, washing hands, social distancing, and proper isolation when we suffer from this.
