The Centers for Disease Control and Prevention (CDC) released a report saying that, in the United States, 2012 was the deadliest year on record for deaths attributed to the West Nile virus.
Texas led the nation, compromising 33 percent of all reported cases with 1,868 infections and 89 deaths. That was far above California, which had the second most reported cases at 479 and 20 deaths.
In the majority of West Nile virus cases, most people experience only minor symptoms such as fever and a mild headache. However, some people who become infected with the virus develop a life-threatening illness that includes inflammation of the brain.
Serious symptoms can include:
- High fever
- Severe headache
- Stiff neck
- Disorientation or confusion
- Stupor or coma
- Tremors or muscle jerking
- Lack of coordination
- Convulsions
- Pain
- Partial paralysis or sudden muscle weakness
