Hornets Have Killed 42 People in China Since July

1,675 injured

Hong Kong (CNN) -- Swarms of aggressive hornets, in their fall mating season, are inflicting a deadly toll in a central Chinese province.

Hornets have killed 42 people and injured 1,675 people in three cities in Shaanxi province since July, according to the local government. Thirty-seven patients remain in critical or serious condition.

Over the summer and early fall, hornets have invaded schools full of children and descended upon unsuspecting farm workers in China.

One of them is Mu Conghui, a woman who was attacked in Ankang City while looking after her millet crop.
