The Mexican Social Security Institute ( IMSS ) notes that dengue is a viral disease caused by the bite of an infected mosquito. Symptoms appear four to seven days after infection and include:

Severe headache
Nausea and/or vomiting
General malaise
Muscle or joint pain
Pain behind the eyes
Rash.

Dengue symptoms can often be confused with other illnesses, such as the flu. In this context, the Mexican government warns people who have recently traveled or live in an area where the disease is common that it is best to immediately suspect dengue and seek care.

It should be noted that people who have previously been infected, infants, and pregnant women are the groups most susceptible to becoming seriously ill.
