Swine Flu H1N1 in Delhi: Symptoms, PCR Test, Treatment & Prevention | Dr Irfan Khan
Swine Flu H1N1 in Delhi
Swine flu, medically known as Influenza A H1N1, is a contagious respiratory viral infection that continues to circulate as part of seasonal influenza.
People with H1N1 may develop fever, cough, sore throat, headache, body aches, blocked or runny nose and significant tiredness.
Most people recover without serious complications. However, influenza can sometimes become severe, particularly in young children, older adults, pregnant women and people with chronic medical conditions.
This educational guide has been prepared and medically reviewed by Dr. Irfan Khan, Consultant Physician & Diabetologist at ZayMed Healthcare Centre, Malviya Nagar, South Delhi.
What is H1N1 Swine Flu?
H1N1 is a type of Influenza A virus. The H1N1 strain that became widely known during the 2009 influenza pandemic subsequently became established as a seasonal human influenza virus.
Although the infection is still commonly called “swine flu”, seasonal H1N1 now spreads primarily from person to person.
The virus spreads through respiratory particles released when an infected person coughs, sneezes, speaks or breathes.
Transmission is more likely during close contact and in crowded or poorly ventilated environments such as homes, schools, offices and public transport.
H1N1 Swine Flu Symptoms
Common symptoms may include:
- Fever or feeling feverish
- Cough
- Sore throat
- Runny or blocked nose
- Headache
- Muscle and body aches
- Chills
- Tiredness or weakness
- Reduced appetite
- Occasionally nausea, vomiting or diarrhoea
Symptoms may appear suddenly and can range from mild to severe.
H1N1 vs Seasonal Flu vs COVID-19
H1N1, other seasonal influenza viruses and COVID-19 can cause overlapping symptoms.
Fever, cough, sore throat, headache, fatigue and body aches may occur with all of these respiratory infections.
It may therefore be difficult to identify the exact infection based on symptoms alone.
A physician may recommend testing depending on the severity and duration of illness, individual risk factors and the respiratory viruses circulating at the time.
H1N1 PCR Test in Delhi
H1N1 can be detected using molecular testing such as RT-PCR performed on an appropriate respiratory specimen.
Depending on the laboratory method, a nasal, nasopharyngeal or throat swab may be collected.
Molecular testing can identify Influenza A and Influenza B. Some assays may further identify influenza subtypes such as H1N1.
When Should You Consider an H1N1 PCR Test?
An H1N1 PCR test may be considered when:
- Symptoms are severe or progressively worsening
- There is significant respiratory illness
- The patient requires hospital assessment
- The patient belongs to a higher-risk group
- Confirming influenza may affect treatment decisions
- Another respiratory infection needs to be differentiated
- A physician considers testing clinically appropriate
Respiratory samples are generally most useful when collected early during the illness.
In seriously ill or high-risk patients, clinically appropriate treatment should not necessarily be delayed while waiting for a laboratory result.
Who Is at Higher Risk of Severe H1N1?
Higher-risk groups may include:
- Adults aged 65 years and above
- Young children
- Pregnant women
- People with diabetes
- People with asthma or chronic lung disease
- People with heart disease
- People with kidney disease
- People with weakened immunity
- People with severe obesity
H1N1 and Diabetes
People living with diabetes should take influenza symptoms seriously.
Infection can cause a stress response in the body and may result in higher blood glucose levels.
Fever, reduced appetite, vomiting and dehydration can also make diabetes management more difficult.
People with diabetes who develop significant flu symptoms should monitor their blood glucose carefully and seek medical advice if readings become difficult to control or if they are unable to maintain adequate food and fluid intake.
Swine Flu H1N1 Treatment
Treatment depends on the patient's age, severity of illness, duration of symptoms and underlying medical conditions.
For uncomplicated influenza, management may include:
- Adequate rest
- Good hydration
- Appropriate medication for fever or discomfort
- Monitoring symptoms
- Reducing unnecessary close contact with other people while unwell
Antiviral Treatment for H1N1
Prescription antiviral medicines such as oseltamivir may be prescribed for suitable patients.
Antiviral treatment is generally most beneficial when started early, ideally within the first 48 hours after symptoms begin.
Treatment may still be beneficial when started later in patients who are seriously ill, hospitalised or at increased risk of influenza complications.
Antiviral medicines should be taken only on the advice of a qualified healthcare professional.
Do Antibiotics Treat H1N1?
No. H1N1 influenza is caused by a virus, so antibiotics do not treat the influenza infection itself.
Antibiotics may be required if a doctor suspects or confirms an additional bacterial infection.
H1N1 Warning Signs: When Should You See a Doctor?
Seek prompt medical attention if you develop:
- Difficulty breathing or shortness of breath
- Persistent chest pain or pressure
- Bluish lips or face
- Severe weakness or confusion
- Severe dehydration
- Inability to maintain adequate fluids
- Reduced consciousness
- Seizures
- Symptoms that improve and then become significantly worse
Parents should seek medical assessment if a child develops breathing difficulty, unusual drowsiness, poor feeding, dehydration or appears seriously unwell.
Can H1N1 Cause Pneumonia?
Yes. Influenza can occasionally progress to viral pneumonia or increase susceptibility to secondary bacterial pneumonia.
Worsening breathlessness, persistent fever, chest discomfort or deterioration after initially improving should not be ignored.
Is H1N1 Swine Flu Contagious?
Yes. Influenza spreads readily between people through respiratory particles, especially during close contact.
If you have flu-like symptoms:
- Limit unnecessary close contact with others
- Cover coughs and sneezes
- Wash your hands regularly
- Consider wearing a well-fitting mask around other people
- Avoid crowded places while significantly symptomatic
- Keep indoor areas well ventilated

Frequently Asked Questions About H1N1 & Flu Vaccination in Delhi
Is H1N1 the same as swine flu?
Yes. Swine flu is the commonly used name for illness associated with Influenza A H1N1, which now circulates as a seasonal human influenza virus.
What are the common symptoms of H1N1?
Common symptoms include fever, cough, sore throat, headache, body aches, chills, nasal symptoms and significant tiredness.
Can you have H1N1 without fever?
Yes. Although fever is common, some people with influenza may not develop a significant fever.
Which test confirms H1N1 swine flu?
Molecular testing such as RT-PCR performed on an appropriate respiratory specimen can detect Influenza A and may identify H1N1 depending on the assay used.
Is fasting required for an H1N1 PCR test?
No. H1N1 PCR testing uses a respiratory sample rather than a fasting blood test.
Does everyone with flu symptoms need an H1N1 PCR test?
No. Testing depends on symptoms, severity, risk factors and clinical assessment. Mild illness does not automatically require laboratory confirmation.
