Dengue fever is not transmitted directly through the respiratory tract or from person to person. However, if you live in an area where someone is sick or has the virus, you are at high risk of getting the disease.

In the mid-1980s, public health practice defined epidemiology as consisting of five main goals. More recently, new tasks have been added to epidemiology.

The dangerous stage of dengue fever starts from the 3rd day to the 6th or 7th day, at this time the patient is in the final days of the dangerous stage, however, be vigilant because complications can still occur.
