b. Cough.
c. Fever.
d. Low Level Of Oxygen.
e. Loss Of Smell.
f. Loss Of Taste.

Symptoms of new corona virus can be severe and may lead to death. Majority of the people who have got infected with this virus are people with some existing medical conditions or senior citizens.

How does Corona virus transmits ?
The identified ways of transmission of this virus are following:
a. Having close contact with person who is already infected
b. If an infected person sneezes or coughs, respiratory droplets released may spread this virus.
How is Corona Virus Diagnosed ?

In order to diagnose the presence of covid-19 infection in an individual, one of the following sample will be acquired from the patient first. Patient need not to necessarily visit a lab to get the sample collected. Sample collection can be done at patient?s home as well.

a. A Swab Test : In this sampling method, a 6-inch long swab is inserted into the cavity between the mouth and the nose and is then rotated several times. To collect enough material for testing, swabbing is repeated on the other side of nose as well. A container is then used to insert this swab into and is sent to lab for testing.
b. A nasal aspirate: In this sampling method, a saline solution is injected into patient?s nose and then this sample is removed with gentle suction.
c. A tracheal aspirate: This method of sampling use a tube called bronchoscope. Bronchoscope is inserted into patient?s lungs. This tube will collect the sample from the lungs.
d. A sputum test: Patient is asked to cough out sputum (Variation of mucus present in person?s lungs) to take a sample of it. Sample of Sputum can also be taken by inserting a swab into the nose in this sampling method. After collecting the sample through any of the method mentioned above, diagnostic test for covid-19 is done.
e. RT-PCR Test : Real-time reverse transcription-polymerase chain reaction tests are diagnostic tests for COVID-19. Presence of viral RNA is detected by this test in human samples. Millions of amplified copies are produced from few copies of DNA by PCR process. Primers and probes (short stretches of DNA) are also required along with human samples for this test. This test uses one probe and two primers against each target region of viral genome. Firstly the viral RNA is converted into DNA is this test and then this DNA is amplified using primers and probe. 15-40 cycles of this steps are repeated to produce millions of copies of viral target DNA. This can then be read by an instrument which confirms the presence of virus. This test is expansive and takes around 24 hours to produce the result.
f. Rapid Antibody Test : In this test, a blood sample is taken. The blood sample is then analyzed to check if antibodies to fight corona infection have been generated yet or not. This test is less expansive and produce result in 20-30 minutes.
There are many labs in india which provides tests for corona virus you can .
BOOK HERE Corona Virus Covid 19 Prevention:
Currently no vaccination is available for Corona Virus. So, prevention is the only option.
Following are the ways through which corona virus can be prevented from spreading :
a. Hands should be washed often with soap of an alcohol based sanitizer.
b. If someone is sick, he should avoid going to public places.
c. Close contact with already infected person should be avoided.
d. While sneezing or coughing, mouth and nose should be properly covered.
e. Eyes, nose and mouth shouldn?t be touched with unwashed hands.
