The dengue virus typically remains in the body for about 5 to 7 days, during which it can be detected in the blood. Most patients recover from the acute phase of the illness within two weeks, but the virus can sometimes persist in certain tissues for a longer time. The duration may vary depending on the individual's immune response and the severity of the infection. It's important to monitor for any complications even after the virus is no longer detectable.

How does dengue enter the human body?
Dengue virus enters the human body primarily through the bite of an infected Aedes mosquito, particularly Aedes aegypti and Aedes albopictus. When the mosquito bites, it injects saliva containing the virus into the bloodstream. The virus then targets immune cells, allowing it to replicate and spread throughout the body, leading to the symptoms associated with dengue fever.
What is Dengue serology IgG iGM?
antibodies against dengue virus which appear in the body in response to infection after Ig M antibodies
Can a person infected with dengue be a lifetime carrier?
No, a person infected with dengue cannot be a lifetime carrier of the virus. While dengue can cause severe illness and complications during an infection, the immune system typically clears the virus from the body. However, infection with one of the four dengue virus serotypes provides lifelong immunity to that specific serotype, but not to the others, meaning a person can still be infected again by different serotypes.
Who spreads dengue?
Our common household mosquito - that is why it is so dangerous to get bitten by any mosquito. Dengue fever is different from our West Nile Virus of which our mosquito is the vector in that your second case of dengue fever can be deadly. It appears that the resistance your body develops to the first attack actually works with the virus on the second attack. That is why they are saying it is going to be 5 years or more before a treatment can be developed.
Why are dengue fever dangerous?
Fever is the body's way of fighting off a bacteria or a virus. The fever seems to slow it down and even inhibit it.
How does the body fight off dengue?
The body fights off dengue by producing antibodies that target the virus and by activating immune cells to destroy infected cells. The immune response helps to control the virus and prevent it from spreading further. In severe cases, the immune response can lead to increased inflammation and tissue damage.
What body system does dengue attack?
Dengue primarily attacks the immune system, specifically targeting the white blood cells and the vascular system. The dengue virus can lead to increased permeability of blood vessels, causing plasma leakage and potentially resulting in severe complications like dengue hemorrhagic fever and dengue shock syndrome. Overall, it disrupts the body's ability to respond to infections and maintain fluid balance.
How many years does HIV live in the body before it is detected?
Once someone gets it, the virus never leaves but if caught early it can be treated before it get a lot worse.
Does dengue make your body swell?
Dengue fever, on the whole, does not make your body swell; however, it should be noted that within 15-30 days of contracting the virus, as the first symptoms begin to appear, the lymph nodes tend to swell up. This could be the source of confusion.

Can dengue be transferred by sperm?
There is currently limited evidence to suggest that dengue virus can be present in human sperm. While studies have indicated that the virus can persist in certain body fluids, including semen, the risk of transmission through sexual contact is not well established. Most dengue transmission occurs through mosquito bites, making it primarily a vector-borne disease. Further research is needed to clarify the potential for sexual transmission.
