New Delhi, Aug 13 - The Delhi government Thursday asked people to exercise caution while visiting crowded places during Janmashtami celebrations Friday.

'People ought to take precautions and should exercise some caution when they are at overcrowded places during Janmashtami celebrations. However, we are not issuing any special guidelines,' Delhi Health Minister Kiran Walia told reporters here.

Walia said people in Delhi, where three new swine flu cases were reported Thursday, were on guard against H1N1 and were taking necessary precautions themselves.

'All three cases are school children and are being put on home quarantine. As on date, 46 swine flu patients are admitted in government hospitals in Delhi,' Walia said.

Delhi has so far reported 315 positive cases and 292 patients have been treated and sent home and remaining are being treated in hospitals.
