Yes, that's a very common practice.

Yuk, yuk. My wife, a physician, had a bad bout with dengue fever (hemorrhagic variety, which is relatively rare but more serious than the regular strain) a month or two ago, in Fortaleza. She doesn't joke about it.

Dengue is found nationwide. The Aedes aegypti, which spreads dengue, can be active at any time of the day. You know the answer to your question, but thatj doesn't mean you can't take precautions, such as wearing long pants and shirts when possible, yes, even using insect repellent. Everyone takes risks. Your call as to how much of a risk to take. You might read up on dengue in advance (e.g., www.cdc.gov) to learn about precuatios and, critically, symptoms, so that if you do exhibit any you will seek treatment, which is usually quickly effective (at least with the regular strain of dengue, which is overhwelmingly the most common).

Use DEET. Most insect repellents contain the chemical DEET, which remains the gold standard of currently available mosquito repellents.

Wear trousers and long-sleeved shirts, particularly at dusk.

Sleep only in screened areas

Air-conditioning may reduce mosquito infiltration. Where air-conditioning is not available, fans may be helpful. Mosquitoes appear to be reluctant to fly in windy air.

Do not wear perfume.

Minimize skin exposure after dusk.

“The mosquito's preferred breeding areas are in areas of stagnant water, such as flower vases, uncovered barrels, buckets, and discarded tires, but the most dangerous areas are wet shower floors and toilet tanks, as they allow the mosquitoes to breed in the residence.”

“It is a daytime biting mosquito with peaks of feeding in the two to three hours after day break, and the couple of hours before dark. However, indoors or on overcast days the mosquitoes may bite all day.”

From Dec to April, it is adviseble to use Deet, specially during the day when that vector (mosquito) is more active. Choosing a higher floor room at the hotel may be a good measure to avoid contact as well.

Depite the fact that the cases in general don´t occur in the most touristic areas of the city (south zone) but in the north, west zones and in the suburbs, it is adviseble to take care because it is something serious that may damage much more than your trip.

Citronella repellent?

Sounds (and must smell) good! Good to know...

Thanks for up-dating us with such a very new way to prevent Dengue fever!

Best regards!

Of no practical use for the present but it maybe of interest to know that there are two long term solutions to the problem that are getting close to fruition. Australian scientists have developed the use of a baccilus that renders the aegyptus mosquito sterile and French scientists have developed a dengue vaccine that is currently undergoing extensive clinical trials. So far it has been shown to be succesful in removing teh risk of infection in three out of the four strains of the disease. Commercial sales are predicted to start in 2015.

There is also another kind of insect repelent that works pretty well and does not make you smelly or sticky. It works by vibration and keeps the insects away.

I do not not exactly how it is called , but you can buy at any outdoor living or camping store.

There is one type that is like a key chain and you can keep it around your neck or in you pocket

I find it very convenient.

That amazing "bio-engineering" tool created by the australians is really interesting and seems to be the most effective since the first trials at the lab.

But sometimes, the mutagenic capacity of a baccilus can be unpredictable and endanger more than protect.
