COVID-19: Testing, Symptoms, Prevention and Health Screening
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. Since its emergence, COVID-19 has affected communities worldwide, including people across India. Although the severity of illness can vary considerably, understanding symptoms, testing options, preventive measures, and when to seek medical attention remains important.
COVID-19 can range from an infection with no noticeable symptoms to an illness requiring medical care. Older adults and people with certain underlying health conditions may have a higher risk of severe disease. Timely medical advice and appropriate testing can help individuals make informed decisions about their health.

What Is COVID-19?
COVID-19 is a respiratory infection caused by SARS-CoV-2. The virus primarily spreads through respiratory particles and aerosols released when an infected person breathes, talks, coughs, or sneezes.
The symptoms of COVID-19 can overlap with those of influenza, common cold, and other respiratory infections. As a result, symptoms alone cannot always establish whether an individual has COVID-19.
Common symptoms may include:
- Fever or chills
- Cough
- Sore throat
- Runny or blocked nose
- Tiredness
- Headache
- Muscle or body aches
- Shortness of breath
- Loss or change of taste or smell in some cases
- Nausea, vomiting, or diarrhoea in some individuals
Symptoms and their severity can vary between individuals and may also change as SARS-CoV-2 continues to evolve.
Why Is COVID-19 Testing Important?
Testing can help determine whether a person has an active SARS-CoV-2 infection when appropriate diagnostic testing is used.
COVID-19 testing may be considered when an individual develops symptoms suggestive of the infection, has been exposed to someone with COVID-19, or has been advised to undergo testing for medical, travel, workplace, or other requirements.
The type and timing of testing matter. Molecular tests such as RT-PCR detect viral genetic material, while antigen tests detect specific viral proteins. Testing too early or at certain stages of infection can influence the result.
Who Should Consider COVID-19 Testing?
Testing may be appropriate for people with symptoms of a respiratory infection or those who have been advised by a healthcare professional to undergo testing.
It may also be relevant for people who have had a known exposure or require documentation for a specific purpose.
People at higher risk of severe illness should be particularly attentive to symptoms and seek medical advice promptly if they become unwell.
You can also explore our diagnostic test packages for other laboratory testing requirements.
How Is COVID-19 Diagnosed?
Diagnosis depends on the patient’s symptoms, exposure history, medical assessment, and appropriate laboratory testing.
For active infection, molecular or antigen-based tests may be used. A healthcare professional can help determine which test is appropriate and when it should be performed.
A negative test result does not always exclude infection, particularly if testing is performed at an unsuitable time or when symptoms strongly suggest an infection. Depending on the situation, repeat testing or further clinical evaluation may be recommended.
Do not rely solely on a laboratory result if you develop worsening symptoms.
COVID-19 and Preventive Health
Preventing respiratory infections involves several practical measures. Staying up to date with recommended vaccinations, improving indoor ventilation, avoiding close contact with people who are unwell, and practising appropriate respiratory hygiene can help reduce the spread of respiratory infections.
If you have respiratory symptoms, consider following current public-health advice regarding staying home, masking, and avoiding close contact with people at higher risk, particularly when infection is suspected or confirmed.
Vaccination remains an important tool for reducing the risk of severe disease, although protection can vary over time and recommendations may change.
COVID-19 in Major Indian Cities
Respiratory infections can affect people living in densely populated urban environments, including major Indian cities such as Delhi NCR, Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Jaipur, and Lucknow.
Large urban populations, frequent travel, workplaces, schools, public transport, and other shared environments can contribute to the spread of respiratory infections.
However, the presence of symptoms does not automatically mean that a person has COVID-19. Other respiratory viruses and illnesses can cause similar symptoms, making appropriate testing and medical evaluation important.
When Should You Seek Medical Attention?
Most people with mild respiratory symptoms can recover with appropriate rest and supportive care, but some individuals can develop serious illness.
Seek urgent medical attention if you experience warning signs such as significant difficulty breathing, persistent chest pain or pressure, new confusion, inability to stay awake, or other severe or rapidly worsening symptoms.
People with underlying medical conditions, older adults, and individuals at increased risk of severe COVID-19 should contact their healthcare professional early when symptoms develop.
How to Prepare for a COVID-19 Test?
Preparation depends on the test being performed.
For a respiratory sample-based test, the laboratory may provide specific instructions regarding sample collection. Follow the instructions provided at the time of booking.
Before testing:
- Confirm which COVID-19 test has been prescribed or selected.
- Check sample collection requirements.
- Follow laboratory instructions carefully.
- Keep relevant medical information available if requested.
- Inform your healthcare professional about significant symptoms or known exposure.
If you are undergoing testing for a specific institutional or travel requirement, verify that the selected test meets the required criteria.

Frequently Asked Questions
1. What is COVID-19?
COVID-19 is an infectious respiratory disease caused by the SARS-CoV-2 virus.
2. What are the common symptoms of COVID-19?
Symptoms can include fever, cough, sore throat, tiredness, headache, body aches, runny nose, and breathing difficulty. Some infected people may have no symptoms.
3. Is COVID-19 still relevant?
Yes. SARS-CoV-2 continues to circulate, and infections can occur. The risk and severity can vary depending on factors such as age, health status, immunity, and circulating variants.
4. Which test detects an active COVID-19 infection?
Molecular tests such as RT-PCR and antigen tests can be used to detect current infection. The appropriate test depends on the circumstances and medical advice.
5. Is an antibody test used to diagnose current COVID-19?
Antibody tests detect an immune response and are generally not the preferred method for diagnosing an active SARS-CoV-2 infection.
6. Do all people with COVID-19 develop symptoms?
No. Some people can have an infection without noticeable symptoms, while others develop mild, moderate, or severe illness.
7. Can COVID-19 symptoms look like a common cold?
Yes. COVID-19 can share symptoms with common colds, influenza, and other respiratory infections. Testing may be needed to distinguish between them.
8. Do I need to fast before a COVID-19 test?
Fasting is generally not the main requirement for respiratory sample-based COVID-19 testing. Follow the specific instructions provided for your selected test.
9. Can I get a COVID-19 test at home?
Home sample collection may be available depending on your location and the test selected. Check availability during booking.
10. How long does a COVID-19 test report take?
The reporting time depends on the test method, laboratory processing, and location. Check the current test details before booking.
11. Can a negative test result completely rule out COVID-19?
Not always. Test timing, sample quality, and the type of test can affect results. If symptoms persist or worsen, consult a healthcare professional.
12. Should I take antibiotics for COVID-19?
Antibiotics treat bacterial infections and do not directly treat viral infections such as COVID-19. Do not take antibiotics unless they have been prescribed by a qualified healthcare professional.
13. Who is at greater risk of severe COVID-19?
Risk can be higher among older adults and people with certain underlying health conditions. Individual risk varies, so medical advice is recommended when symptoms develop.
