Now the risk of human-to-human transmission is high, so it is imperative to take all precautions. It is also the season when the common cold is prevalent and it cannot be distinguished from swine flu.'

In Delhi, 178 people have been discharged after treatment for H1N1, while 58 are still undergoing treatment.

To raise awareness about the infection, Residents Welfare Associations (RWA) are trying to pitch in as well.

Rajiv Kakaria of south Delhi's Greater Kailash RWA told IANS: 'On our part we are prepared for an all-out war against the H1N1 virus as we are trying to keep our area clean. We are also in touch with MCD officials.'

'We have informed residents about a few simple steps - if you are not well, take a few days off and stay at home, if your domestic help is showing symptoms, ask her or him to take leave.'

Other RWAs across Delhi want to organise awareness camps.

'We have written to the government that just like they organise awareness camps about do's and don'ts for curbing the spread of malaria and dengue, they should do the same for swine flu,' Kakaria said.

Others say the 14 testing centres for Delhi's 16 million plus population aren't enough.

'In panic people are queuing up at the centres for testing, and that won't do. Keeping in mind the population of the capital, the Delhi government should announce more testing centres. East Delhi is the highest populated area but the government has set up only two testing centres there,' said N.N. Mishra, president of the Mayur Vihar Pocket F RWA.
