If you have suffered from dengue last year, you need to be more careful as the second attack of dengue may be more dangerous than the first attack.

There are four different types of dengue and one can, therefore, suffer with dengue four times in his or her lifetime. The second or subsequent dengue infections tend to be more serious.

A person with dengue can also simultaneously suffer from malaria. Malaria and dengue together can lower platelet counts to a dangerous level leading to complications.

In a dengue season, nobody should take aspirin for fever as it can precipitate bleeding, he added.

In dengue most complications occur within two days of the fever subsiding and most people are casual during this period. Any type of abdominal pain, giddiness or weakness after the fever has subsided should be attended to, by a doctor. Dengue complications during this period are due to shift of blood volume and patient requires rapid infusion of oral or intravenous fluids in large quantity.

Platelet transfusion is not required even if the count is as low as 10000 unless there is an associated bleeding.
