Effect of Dengue on Circulatory System

Dengue fever is a disease transmitted by mosquitoes infected with the dengue virus. It results in severe flu-type symptoms accompanied with high fever and intense pain in muscle and joints. Effect of Dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), the two advanced stages of the disease, can be fatal but they are not very common. It is the DHF and DSS that has a serious impact on circulatory system. When dengue fever progresses to a more acute stage, the blood vessels stop functioning and flow of blood is disrupted. This causes a collapse of the circulatory system with possibly fatal consequences.

Symptoms of Dengue Indicating Circulatory System Collapse

• Nausea
• Vomiting
• Abdominal pain
• Sudden Collapse
• Extreme cool clammy sensations.
• Weak Pulse
• Blueness around the mouth
• Easy bleeding and bruising
• Red spots in the skin called petechiae.
• Spitting blood.
• Blood in passing stool.
• Bleeding of gums and nose.
• Inflammation of the heart.

Effect of dengue on the circulatory system is particularly damaging to children less than 10 years of age. The mortality ranges from 6 to 30% and most deaths due to dengue hemorrhagic fever occur in children. Infants less than one year old are even more at risk of dying due to this condition.
