Dengue virus primarily affects immune cells, particularly macrophages and dendritic cells, which are key components of the immune response. The virus can also impact endothelial cells lining blood vessels, leading to increased vascular permeability and contributing to symptoms like bleeding and plasma leakage. Additionally, liver cells may be affected, resulting in liver dysfunction in severe cases. Overall, the systemic nature of dengue can lead to widespread tissue involvement.

Dengue fever primarily affects humans and is transmitted by the Aedes mosquito. There is no evidence to suggest that animals can contract dengue fever.
In a person affected by dengue, urine may appear darker than usual, often resembling tea or cola. This change in color can be due to dehydration or the breakdown of red blood cells, which may occur in severe cases. It’s important for individuals with dengue to stay hydrated and seek medical attention if they notice significant changes in urine color or experience other concerning symptoms.

Retro-orbital pain during dengue fever is primarily attributed to the inflammation of the tissues surrounding the eyes, which can occur due to the viral infection and the body's immune response. The release of cytokines and other inflammatory mediators can lead to increased pressure and discomfort in the ocular region. Additionally, the fever and systemic symptoms associated with dengue can exacerbate this pain, making it a common complaint among affected individuals.
In dengue fever, white blood cells can decrease because the virus directly targets and destroys them. Additionally, the viral infection can trigger the immune system to release certain chemicals that can suppress the production of white blood cells. This decrease in white blood cells can make the body more vulnerable to infections.
Fluid leakage in dengue refers to the abnormal accumulation of fluid in the body's tissues and cavities, which can occur during the critical phase of the infection, particularly in severe cases. This phenomenon is primarily caused by increased vascular permeability due to the dengue virus's impact on the endothelial cells lining blood vessels. If not managed properly, fluid leakage can lead to complications such as shock, organ failure, and potentially death. Monitoring and timely intervention are crucial to prevent severe outcomes in dengue patients.
