Britain's health minister has cautioned doctors to prepare for a “much stronger” version of the H1N1 virus to surface this autumn, the Telegraph reports. With 985 cases confirmed in 20 countries so far, the World Health Organization is also countering Mexico’s optimism that the virus is on the wane with a warning that it could rebound in an even nastier form, CNN reports.
"In 1918 the Spanish flu showed a surge in the spring, and then disappeared in the summer months, only to return in the autumn of 1918 with a vengeance," warned a WHO spokesman. "It eventually killed up to 50 million people."
