Dengue Fever: Mosquito Born Illness Now Found In Texas, Florida, And Hawaii

Asian tiger mosquito, Aedes albopictsDengue fever is a viral (flavivrus) disease transmitted by Aedes albopictus and female A. aegypti mosquitoes. It is estimated that 50 to 100 million people in more than 100 countries are infected each year with dengue viruses.

There are four different types of dengue virus, and there is no cross-immunity, so a person may be stricken with dengue fever four times in his life. The most active feeding times for dengue vector mosquitoes is for a few hours after daybreak and in the afternoon for a few hours just after dark (dusk).

As opposed to the night-feeding mosquitoes that transmit malaria, these species tend to be “urban,” may also feed during daylight hours (also indoors, in the shade, and during overcast weather), and are known to bite below the waist. Dengue fever is seen chiefly in the Caribbean and South America, as well as other tropical and semitropical areas, such as Southeast Asia, Africa, and Mexico. In the United States, cases have been noted in Texas, Hawaii and Florida. The larvae flourish in artificial water containers (e.g., vases, tires), often in a domestic environment.

After all, Hollywood is hot for drama, and when it comes to portraying a person having a heart attack, the exaggerated Hollywood version is far more riveting than a person sitting quietly wondering if their very slight arm discomfort is anything they should be concerned about.

The Hollywood version can be very misleading. Read more »

Why Not To Drop Your Baby On His Head

Exaggeration, drama, and histrionics are very much the rule of thumb in the ER.  Someone comes in and claims they were stabbed with an eight-inch butcher’s knife, and the police later bring in the actual weapon, and it turns out to be a three-inch penknife.  Someone claims to have taken a whole bottle of tylenol, but their serum levels turn out to be nowhere near the toxic level (or even zero).  A patient reports to you that their last pneumonia was so bad their doctor didn’t think they’d pull through, but you check the records and see they weren’t even in the ICU.  (The sole exception to this rule, of course, is the stated alcohol intake, which is usually about half to a third the actual alcohol intake.)
