U.S. health officials say there's been an alarming increase in the number of West Nile cases.

So far, there have been more than 1,100 cases of the sometimes deadly virus reported through the middle of August. That's three times as many as usually seen at this point in the year. Most West Nile infections are reported in August and September.

About half the cases are in Texas.
