Swine flu alerts fake: National Institute of Virology, didn't recommend Nilgiri oil

Swine flu SMSes and email alerts being sent in the name of National Institute of Virology (NIV) have been found to be spam and promotional tricks.
NIV authorities said they have not recommended any indigenous products such as Nilgiri oil for use against H1N1 virus.
NIV has asked citizens to to refer to the public health information issued by the government.
Several SMSes are doing rounds advising public to use Nilgiri oil drops on masks as preventive measure against swine flu.
Another SMS asks to take five tulsi (ocimum) leaves a day to keep the flu away.
