Why Platelet Count Decreases in Dengue Fever?

One of the fearful diseases that is doing rounds in recent years is Dengue fever. If someone complains of fever and joint pain, the very first question that pops up in our mind, have they done any test for dengue? It is caused by a virus carried out by female infected mosquito Aedes aegypti.

Platelet Count in Dengue Fever

Blood is made up of three types of cells. The liquid form is called plasma, RBCs are oxygen-carrying cells and White Blood cells fight against infection and provide immunity. The third type is platelet which helps in blood clotting. In the normal human body, the platelet count in dengue ranges from 1.5 lacs to 4 lacs, while platelet count in dengue decreases to as low as 20,000 to 40,000, you need to follow certain steps in increasing the platelet count in dengue fever patients.

Platelets also are known as thrombocytes are small blood cells that are produced in the bone marrow.  Decreased platelets count in dengue fever means that blood has lost its clotting abilities and is not able to fight against infection.

Why does Platelet Count decrease in Dengue Fever?

In dengue platelet, count and white blood cells decrease in number which affects the immunity system. This happens because of the following:

  • Platelet count in dengue decreases as it suppresses bone marrow, which is the platelet-producing area.
  • Platelets count in dengue decreases because of Blood cells affected by the disease virus damage platelets.
  • Antibodies that are produced during this period leads to massive destruction of platelets in dengue.

Symptoms of Dengue fever

Symptoms develop 4 to 7 days after the bite of mosquito which includes high fever, vomiting, pain behind the eyes, headache, nausea, and severe muscular and joint pain. Pain in the eye and joint lead to the suspicion of the dengue fever. The fever lasts for about 5 to 7 days and is followed by a prolonged period of fatigue, joint pains, body pain, and rashes (learn more about Painful Rashes). For the sake of confirming the diagnosis, the doctor will run some lab tests.

These include testing for antibodies IgG and IgM, PCR testing to check the virus, and a complete blood count. This will reveal the decrease in the white blood cells and the platelets in dengue. There isn't a particular level below which a person would require platelets in dengue. In aged people and with people who have other chronic diseases, platelet transfusion may be required even if the blood count is about 50,000.

The doctor will decide this based on the patient’s health. The right thing to do is to go for medical consultation and discuss your situation with the doctor and identify what needs to be done for your condition specifically.
