"How Mosquitoes Transmit Dengue Virus?"

Dengue Virus and Dengue Fever

The dengue virus is the causative agent of dengue fever, primarily transmitted through mosquito bites. Upon infection with the dengue virus, patients may experience symptoms such as fever, rash, muscle pain, among others.

Sources of Infection

The dengue virus resides in the blood, saliva, urine, and other bodily fluids of infected individuals and patients. It is highly contagious typically 6-18 days before the onset of symptoms and within 3-5 days after the onset.

Routes of Transmission

The dengue virus can be transmitted through contaminated water sources like swimming pools, sewage systems, and wastewater. Exposure to objects bitten by virus-carrying mosquitoes may also lead to infection.

Susceptible Populations

The dengue virus is universally susceptible among people, with children and adolescents being more commonly affected. Pregnant women infected with the dengue virus may face complications affecting fetal development, increasing the risk of fetal malformations or stillbirths.

Clinical Manifestations

Following dengue virus infection, patients may experience fever, with temperatures reaching over 39°C, accompanied by headaches and muscle aches. Skin rashes, manifesting as maculopapular or measles-like lesions, also occur. Some patients may exhibit bleeding tendencies, such as gum bleeding or nasal bleeding. If you suspect a dengue virus infection, immediate medical attention is advised.

Treatment and Management

Upon diagnosis, antiviral medications such as Acyclovir can be prescribed under medical supervision for treatment.
