Delhi H1N1 Cases Rise as Government Urges Mask Use
Delhi has seen more cases of H1N1, a virus that can cause flu.
The government is asking people to help slow its spread.
People should wear masks in crowded indoor places and cover their mouths when coughing or sneezing.
Washing hands and avoiding touching the face with dirty hands can also help.
Sick people should stay away from others when they have a fever or strong breathing symptoms.
Most people get better with rest and supportive care.
Flu can be more dangerous for older adults, pregnant women, young children and people with some health problems.
Trouble breathing, chest pain, confusion, low oxygen or symptoms that get worse are warning signs that need a doctor.
Delhi has reported more than 1,777 H1N1 cases this year, including 114 new infections on Thursday.
The capital has also recorded more than 2,300 Influenza-A cases, prompting increased preparedness.
Authorities recommend masks in crowded or poorly ventilated places, handwashing and covering coughs and sneezes.
H1N1 spreads mainly through respiratory droplets and can also spread through contaminated surfaces.
Most infections resolve with supportive care, but breathlessness, chest pain, falling oxygen or worsening symptoms require medical attention.

Vigilance Without Panic
Seriousness Requires Caution
How people should respond
Vigilance Without Panic
Dr Arjun Khanna says the message should be vigilance rather than panic because most influenza infections are self-limiting.
Seriousness Requires Caution
Authorities and medical guidance stress that persistent or worsening flu symptoms should not be dismissed as ordinary seasonal flu.
Risk of complications
Vigilance Without Panic
Many people recover with supportive care without serious complications.
Seriousness Requires Caution
Influenza can progress to viral pneumonia, low blood oxygen and respiratory failure, especially among vulnerable groups.
Use of medication
Vigilance Without Panic
Routine antibiotic use is not helpful because H1N1 is caused by a virus.
Seriousness Requires Caution
Antibiotics may be considered only after medical evaluation confirms a secondary bacterial infection; unnecessary use can contribute to antimicrobial resistance.
