More People Have Died From China's New Bird Flu

The impact of the new bird flu infecting China just keeps adding up.

On Thursday, April 11, five more confirmed cases of the new bird flu, H7N9, were reported to the World Health Organization. This is on top of four new cases announced April 10.

The total is now 39 infections and 10 dead:

While the number of infected and dead keep rising, there aren't signs yet that the virus has mutated to be able to pass between humans directly. The infected people probably came into contact with an infected bird. Birds don't show any signs of the virus, so it's hard to tell when the animals are infected. That's why China has been conducting a mass slaughter of birds at poultry markets throughout Shanghai.
