All about Dengue
The virus – Causative Organism
The dengue virus (DEN) comprises four distinct serotypes (DEN-1, DEN-2, DEN-3 and DEN-4) which belong to the genus Flavivirus, family Flaviviridae.
The mosquitoes – The transmitter
Dengue fever is transmitted by mosquitoes – notably two species, Aedes aegypti and Aedes albopictus. mosquitoes are the main vectors that transmit the viruses that cause dengue. The viruses are passed on to humans through the bites of an infective female Aedes mosquito.
Up to 50-100 million infections are now estimated to occur annually in over 128 endemic countries including INDIA putting almost half of the world’s population at risk.More than 200,000 deaths result from the virus every year.The World Health Organization (WHO) estimates that about 40% of the world’s population is at risk of being infected with dengue. All age groups are at risk. What Happens in the human body in Dengue.
Dengue suppresses bone marrow (which is the platelets producing area Platelets help in blood clotting) and hence decreased Platelets count.Normal platelets count in the body ranges from 1.5 to 4 lacs / (micro liter) and in patients with dengue; this can go down to as low as 20,000 to 40,000. means Severe Bleeding occur all over the body.
This complication of dengue causes abdominal pain, hemorrhage (bleeding), and circulatory collapse (shock), Dengue hemorrhagic fever (DHF) is a specific syndrome that tends to affect children under 10 years of age is serious and fatal
There is no specific treatment for dengue fever. There is no proper vaccine too.
Patients should seek medical advice, rest and drink plenty of fluids.
Increases Blood Platelet count quickly . It is especially effective when there is a sharp decline in platelet count, such as in cases of dengue fever and malaria. Ref: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5108100/
