“All of Cienfuegos is topsy-turvy because of the dengue issue,” local janitor Idolidia Velazquez told reporters. “No one is going to the hospitals because they are full of patients with the disease. It’s something not seen in years. People are very afraid.”

Officials have increased spraying in the area against the Aedes Aegypti mosquito, which has also been known to transmit both yellow fever and Zika.

Symptoms of dengue virus

The most common symptom of the four dengue related viruses (DENV1, DENV2, DENV3 and DENV4) is a high fever. Headache, severe pain behind the eyes, joint and muscle pain as well as rash and bleeding in the gums and nose are also indicators that you may have contracted a form of the virus.

Dengue hemorrhagic fever (DHF) is the most severe form of dengue virus that causes a fever that can last up to seven days, followed immediately by vomiting, abdominal pain and difficulty breathing. If treated in time, the CDC reports that the mortality rate of  DHF is less than one per cent.

Treatment for dengue virus 

There is no set course of treatment for dengue fever or DHF. It is recommended that those infected treat their symptoms with pain relievers such as acetaminophen, drink plenty of fluids to prevent dehydration and avoid taking aspirin, ibuprofen or Naproxen.

Preventing dengue virus 

Without a vaccine, insect repellant is the most effective way to prevent the transmission of the dengue virus whether indoors or outside. Look for repellants with active ingredients DEET, Picaridin (also known as KBR 3023 or icaridin) , IR3535, oil of lemon eucalylptus (OLE or PMD) or 2-undecanone.

For those who live in or are travelling to at risk areas, avoid areas with standing water and wear long sleeves. Sleeping under mosquito netting can also help prevent bites indoors.

Dengue is only transmitted by mosquitos and not person to person. Should someone become infected, continue to take precautions to avoid another mosquito bite.
