(AP) -- The World Health Organization has increased its tally of confirmed swine flu cases around the world to 236 from 148.
The global body says most of the new confirmed cases came from Mexico.
WHO's flu chief Keiji Fukuda said Thursday the number of confirmed cases in Mexico has increased to 97 from 26, including 7 deaths.
WHO's tally of confirmed cases has lagged behind those that individual countries report because it has to wait for formal notification from the affected nation.
