India says it is fully equipped to deal with the disease
More people have tested positive for swine flu in India, bringing the total number of those infected in the country to 23, according to reports.
Fresh cases have been detected in the northern city of Jalandhar, as well as Hyderabad and Bangalore in the south.
These include a student who tested positive on returning from a trip to US. Eight of his classmates are suffering from flu symptoms.
Last week the World Health Organization (WHO) declared the global flu pandemic.
The swine flu (H1N1) virus first emerged in Mexico in April and has since spread to 74 countries.
Official reports say there have been nearly 30,000 cases globally and 141 deaths, with figures rising daily.
In India, a 29-year-old woman and her three-year-old daughter who had flown in from US were quarantined in Bangalore after testing positive for the virus.
In Jalandhar, eight students were quarantined when one of their classmates tested positive for swine flu in a hospital in the capital, Delhi.
They were part of a group of students who had returned from the US at the weekend.
In Hyderabad, reports say three people tested positive, including two girls and their grandmother. They also had returned from the US.
Earlier this month, India issued an alert against the flu. Airport screening has been tightened and more testing facilities would come.
The government has said that India was fully equipped to deal with the outbreak.
