Infected RBC trigger platelet to produce PF4 protein, which activate monocyte (Macrophage) to clear platelet from circulation by sequestration in spleen. which leads to high production of platelet (so giant platelet ) and decreased platelet on smear.

Symptoms include fever, headache, muscle and joint pains, and a skin rash. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets or into dengue shock syndrome, where dangerously low blood pressure occurs.
A striped Aedes aegypti mosquito that has previously bitten an infected person. Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the dengue virus.Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
The life span of a platelet is around a week.
its something called plasma leakage. patient with just dengue didnt suffer plasma leakage, but the other with dengue hemorrhagic fever does. you can know whether someone get a plasma leakage from: 1. anamnese: difficult to breath (due to a pleural effusion), distended abdomen (due to an ascites) 2. phys. diagnostic: derivation of breathing sound, undulation test, edema, poor perfusion and shock sign 3. lab findings: hemoconsentration (higher Hb and PVC)
platelets have a life span of 8 to 10 days normally in body. In transfused blood the life span is 2-3 days Platelets have a life span for about 5 to 10 days. And it is the Red Blood Cell that has a lifespan for 120 days

No, there is no animal called a dengue. Dengue is a viral infection transmitted by mosquitoes, primarily the Aedes aegypti mosquito. It is a significant public health concern in tropical and subtropical regions, causing symptoms such as fever, severe joint and muscle pain, and potentially life-threatening complications. It is important to take preventive measures to avoid mosquito bites and reduce the spread of dengue fever.

The answer, unfortunately, is possible. There are four types of dengue virus. If a person is infected by any one of those four types, though it is not entirely impossible to die from it, it very rarely happens. It can even act like a vaccine, providing some immunity from the same type of virus to the infected person. However, if the same person (already infected by one of the four types some times before) gets infected from a different type, - any other of the remaining three, -dengue fever could develop into a more severe form, - earlier known as Dengue Haemorrhagic Fever, presently called as Severe Dengue Fever. That severe form could be fatal. There is neither vaccination nor specific treatment against either Dengue Fever or its more dangerous form, the Severe Dengue Fever. However, prompt medical care could often save life even in the case of the severe form. Since Severe Dengue Fever patients are loosing serious amounts of body fluids, - including blood -, the most vital treatment is keeping the fluid level to optimal, thus diminishing the complications which could have lead to death. More detailed information can be found in the related links.
Dengue fever is a mosquito-borne viral illness caused by the dengue virus, primarily transmitted by Aedes mosquitoes, particularly Aedes aegypti. It is characterized by high fever, severe headaches, joint and muscle pain, rash, and mild bleeding. In some cases, dengue can progress to severe forms, such as dengue hemorrhagic fever or dengue shock syndrome, which can be life-threatening. Prevention focuses on mosquito control and avoiding bites, as there is no specific antiviral treatment for the disease.
