The West Nile virus is back, and it's looking like it could be particularly bad this year. As as result, federal health officials are warning people to protect themselves against the mosquito-borne infection.
The West Nile virus first showed up in the U.S. in 1999 and quickly spread from coast to coast, raising widespread alarm. Some have argued that red-breasted robins play a key role in the spread of the virus.

An outbreak of the Ebola virus has emerged in western Uganda.
Twenty cases were reported by the World Health Organization yesterday. At least 14 people have died. The number of Ebola infections is expected to rise in the next few days, as more patients are admitted to hospitals.
The outbreak began in a rural district of Uganda about 125 miles west of the Uganda capital, Kampala.
