Swine flu spreads. As per the reports appeared in the media (WHO), there are 900 confirmed cases of Swine flu worldwide in 19 countries. The WHO may raise H1N1 outbreak alert to the highest level 6. Canada reported the world’s first case of the flu virus jumping to pigs to a human, a farm worker who visited Mexico.
Mexico has 506 cases plus 101 deaths, while USA has 226 cases plus 1 death. There are also news items which says hundreds of visitors quarantined at a hotel in Hong Kong after guests contract H1N1 virus. India has no confirmed cases of swine flu.
Meanwhile, news papers and TV show people wearing all types of respirators, face masks as precautionary measures. There are different types of respirators meant for different pollutants. For example particulate filters, such as High Efficiency Particulate Air (HEPA) filters may not trap gaseous pollutants. The respirators should be fit-tested and disposable type and not to be reused/recycled.
The media should highlight the types of filters and the efficiency of each type of respirators to trap the virus. The efficiency may vary depending on the filter type and the fit.
