We have some more tentatively encouraging news emerging about the Swine Flu virus.

Yesterday, we noted that the Mexican government had substantially revised downward the number of deaths attributed to the Swine Flu, from 159 to 84, after tests had ruled out many of the suspected cases.

Now comes word from the Times that Mexican officials have now reported that of the 908 suspected cases that have now been tested, only 397 turned out to have suffered from the Swine Flu.

Finally, there appears to be some clinical evidence suggesting that people over 60 may have some immunity to the virus.
