Understanding COVID-19 Tests & The Significance Of Viruses

COVID-19-Testing

Coronavirus is a family of viruses that affect people and animals. There are three types of coronavirus: SARS, MERS, and NCoV. While these three diseases are similar in some ways, they also have unique differences that require different methods to diagnose or treat them. This article examines the three types of coronavirus and how they are different from one another.

  •  What Are The 3 Types Of COVID-19 Tests?

There are three types of coronavirus disease tests;
-First: Is an RT-PCR test that detects the virus directly. This test is done on the blood or respiratory secretions of a person suspected of having the coronavirus.
-Second: The test looks for antibodies produced by the immune system to fight the disease. This is called a serology test.
-Third: It identifies the virus based on patterns of amino acids in the virus particles.
The results of these tests depend on who is being tested, the time between testing and when the results are reported, and the patient’s health and age.

Covid causes fever, headache, confusion, shortness of breath, vomiting, and internal and external bleeding. Symptoms usually appear between an hour and a day after exposure. However, as the disease progresses, the symptoms become more frequent, than intense, and can last much longer.

  • How Is SARS Different From MERS & NCoV?

-SARS is Severe Acute Respiratory Syndrome. It is a respiratory illness caused by a virus called SARS-CoV. SARS-CoV, which stands for Severe Acute Respiratory Syndrome coronavirus, is the virus that causes SARS. It’s usually transmitted through close physical contact—for example, coughing or sneezing into the nose or eyes. Most people get infected when they cough or sneeze into a broken or swollen lung. People start getting sick in 2 to 9 days, with short-term recovery or sometimes no symptoms at all. SARS often has no signs or symptoms in infected people. Anyone can get infected with SARS. 

-MERS is Middle Eastern Respiratory Syndrome. It is similar to SARS in many ways. For example, about one in five people who get infected with MERS will also get infected with SARS. However, MERS differs in a few important ways, including whether it causes pneumonia, and how severe the illness is. About 90% of people who get infected with MERS have no symptoms. The remaining 10–15% of infected people develop severe pneumonia as their lungs and other body organs fill with fluid. 

  • What Are The Symptoms Of SARS, MERS, & NCoV?

-SARS symptoms include fever, cough, headache, and muscle aches.
-MERS symptoms include fever, cough, shortness of breath, and diarrhea.
-NCoV symptoms include fever, muscle aches, and headache.

If you are experiencing any of these symptoms, seek medical attention immediately. As long as you do not have other underlying conditions, you should be fine.

  • How Is SARS Treated?

SARS is an acute respiratory syndrome that is caused by a novel coronavirus (the virus family that includes the common cold). The virus is spread from person to person through droplets.
A breathing tube may be required for improved survival.
Two hallmark symptoms of SARS have been recognized: pneumonia and elevated liver enzymes (ALT). The liver enzymes produce toxins that damage and kill liver cells. Septicemia, inflammation of the lungs, appeared as early as 2 weeks after infection. 

MERS cases tend to run a coin flip among healthcare workers within a medical facility. After 90 days of illness or about 10 days after infection, a person has a 1 in 2,000 chance of developing pneumonia. About 60% of MERS patients develop pneumonia compared with 30% of SARS cases, according to The New York Times.

NCoV is a type of coronavirus that is inherited in families, and it predominantly affects humans. Like SARS, symptoms of NCoV begin suddenly and gradually improve over time. Like SARS, NCoV is contagious within a human or animal household.
