Dengue Fever Surges in Latin America & the Caribbean
Dengue Fever Surges in Latin America and the Caribbean

Dengue fever is spreading across Latin America and the Caribbean in one of the worst outbreaks in decades, causing agonizing joint pain for hundreds of thousands of people and killing nearly 200 so far this year.
A home in El Salvador is fumigated to rid it of mosquitoes transmitting the dengue fever in September of 2006. Four different strains of dengue are spreading thoughout the Americas, worrying officials.
The mosquitoes that carry dengue are thriving in expanded urban slums scattered with water-collecting trash and old tires. Experts say dengue is approaching record levels this year as many countries enter their wettest months.
"If we do not slow it down, it will intensify and take a greater social and economic toll on these countries," said Dr. Jose Luis San Martin, head of anti-dengue efforts for the Pan American Health Organization, a regional public health agency.
The U.S. Centers for Disease Control and Prevention in Atlanta has posted advisories this year for people visiting Latin American and Caribbean destinations to use mosquito repellant and stay inside screened areas whenever possible.
"The danger is that the doctors at home don't recognize the dengue," said Dr. Wellington Sun, the chief of the CDC's dengue branch in San Juan. "The doctors need to raise their level of suspicion for any traveler who returns with a fever."
Dengue has already damaged the economies of countries across the region by driving away tourists, according to a document prepared for a PAHO conference beginning Monday in Washington.
Some countries have focused mosquito eradication efforts on areas popular with tourists. Mexico sent hundreds of workers to the resorts of Puerto Vallarta, Cancun and Acapulco this year to try to avert outbreaks.
Health ministers from across the region meet at the PAHO conference and San Martin said he will urge them to devote more resources to dengue fever.
The tropical virus was once thought to have been nearly eliminated from Latin America, but it has steadily gained strength since the early 1980s. Now, officials fear it could emerge as a pandemic similar to one that became a leading killer of children in Southeast Asia following World War II.
Officials say the virus is likely to grow deadlier in part because tourism and migration are circulating four different strains across the region. A person exposed to one strain may develop immunity to that strain - but subsequent exposure to another strain makes it more likely the person will develop the hemorrhagic form.
"The main concern is what's happening in the Americas will recapitulate what has happened in Southeast Asia, and we will start seeing more and more severe types of cases of dengue as time progresses," Sun said.
The disease - known as "bonebreak fever" because of the pain - can incapacitate patients for as long as a week with flu-like symptoms. A deadly hemorrhagic form, which also causes internal and external bleeding, accounts for less than 5 percent of cases but has shown signs of growing.
So far this year, 630,356 dengue cases have been reported in the Americas - most in Brazil, Venezuela, or Colombia - with 12,147 cases of hemorrhagic fever and 183 deaths, according to the Pan American Health Organization. With the spread expected to accelerate during the upcoming rainy season in many countries, cases this year could exceed the 1,015,000 reported in 2002, according to San Martin.
In Puerto Rico, where 5,592 suspected cases and three deaths have been reported, some lawmakers called this week for the health secretary to resign.
In the Dominican Republic, which has reported 25 deaths this year, the health department announced Thursday that it would train 2.5 million public school students to encourage parents and neighbors to eliminate standing water.
Researchers have not yet developed a vaccine against dengue and Sun said that for now, the only way to stop the virus is to contain the mosquito population - a task that relies of countless, relentless individual efforts including installing screen doors and making sure mosquitoes are not breeding in garbage.
"It's like telling people to stop smoking," he said. "They may do it for a while, but they don't do it on a consistent basis and without doing that, it's not effective."
While dengue is increasing around the developing world, the problem is most dramatic in the Americas, according to the CDC.
Health officials believe the resurgence of the malaria-like illness is due partly to a premature easing of eradication programs in the 1970s.
Migration and tourism also have carried new strains of the virus across national borders, even into the United States, which had largely wiped out the disease after a 1922 outbreak that infected a half-million people.
Mexico has been struggling with an alarming increase in the deadly hemorrhagic form of dengue, which now accounts for roughly one in four cases. The government has confirmed 3,249 cases of hemorraghic dengue for the year through Sept. 15, up from 1,924 last year.
The CDC says there is no drug to treat hemorrhagic dengue, but proper treatment, including rest, fluids and pain relief, can reduce death rates to about 1 percent.
San Martin said he use the meetings starting Monday to urge enforcement of trash disposal regulations, more investment in mosquito control and new incentives for communities to participate.
"It is a battle of every government, every community and every individual," he said

that I paid 85 Pesos for. They very conveniently had put a label on the expiration date so I didn't notice it when I bought it until later. Alaska Airlines treated me well because of my problem and that's when we discovered it. What a scam artists they are in Mexico even at the Paradise Village Mall! I'll bet you that it will be cheaper here at home but you may need a doctor's prescription here, I believe? This problem seems to be very common in Mexico but it was the first time for me and I survived it.
