CDC: Dengue Fever
The CDC estimates there are 10 million cases of dengue around the world each year. Symptoms include high fever, severe headache, backache, joint pains and eye pain, nausea, vomiting and a rash, according to the CDC.
Dengue hemorrhagic fever, a more severe form of the virus, "can be fatal if unrecognized and not properly treated," the CDC said. However, with treatment, fatalities due to DHF can be less than 1 percent, the CDC said.
The Rio de Janeiro Health Ministry said 513 of its 57,010 cases of dengue were that of the dengue hemorrhagic fever virus. It did not identify how many of the 67 deaths were from the dengue hemorrhagic fever or "classic" dengue.
There is no vaccine to prevent dengue or dengue hemorrhagic fever, the CDC said.
