The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
The virus was first identified in December 2019 in Wuhan, China.
Common symptoms include headache,loss of smell and taste, nasal congestion and runny nose, cough, muscle pain, sore throat, fever, diarrhea, and breathing difficulties.
People with the same infection may have different symptoms, and their symptoms may change over time.
Three common clusters of symptoms have been identified:
1)one respiratory symptom cluster with cough, sputum,
2)shortness of breath, and
3)fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhea.
In people without prior ear, nose, and throat disorders, loss of taste combined with loss of smell is associated with COVID-19.

The Real-Time RT–PCR is suitable to detect the COVID-19 virus as it contains only Ribonucleic Acid.
The full form of RT-PCR is Reverse Transcriptase Polymerase Chain Reaction. It is the most sensitive technique for mRNA detection.
It quantifies the presence of a particular genetic material of the virus or any pathogen.
Real-Time RT-PCR is loaded with fluorescent dyes as markers.

The Rapid Antigen Detection Test (RADT) for COVID-19 is a rapid point-of-care nasopharyngel swab test that directly detects the presence or absence of coronavirus antigen in the patient’s body, generating diagnosis results within 30 minutes.
These tests are designed to detect a specific protein in the virus that elicits the body’s immune response.
An antigen test reveals if a person is currently infected with a pathogen such as the SARS-CoV-2 virus. Once the infection has gone, the antigen disappears.

An antibody test is a screening for things called antibodies in your blood. Your body makes these when it fights an infection, like COVID-19. The same thing happens when you get a vaccine, like a flu shot. That’s how you build immunity to a virus.

You may also hear it called a serology test.

The antibody test isn’t checking for the virus itself. Instead, it looks to see whether your immune system -- your body’s defense against illness -- has responded to the infection.
