Deadly virus infects ninth person

Yosemite National Park officials have expanded a warning about the deadly hantavirus to 230,000 more recent visitors, after confirming a ninth person had contracted the virus which has already killed three people.

Yosemite had previously alerted 30,000 visitors, who slept in two locations, but expanded the warning by sending emails to 230,000 more who stayed elsewhere for the sake of caution.

The latest person confirmed to have been infected with hantavirus stayed in Yosemite in July. The Californian has now recovered, however.
