Dengue virus is a mosquito borne illness and is a major threat in most of the tropical and sub-tropical countries around the world. There are four related subtypes of the Dengue virus. Dengue is not transmitted directly from person-to-person and symptoms range from a mild fever, to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. There is no vaccine or any specific medicine to treat dengue. People who have dengue fever should rest, drink plenty of fluids and reduce the fever using paracetamol or see a doctor. | Dengue virus is a mosquito borne illness and is a major threat in most of the tropical and sub-tropical countries around the world.

In the infectious form of the virus, the envelope protein lays flat on the surface of the virus, forming a smooth coat with icosahedral symmetry. However, when the virus is carried into the cell and into lysozomes, the acidic environment causes the protein to snap into a different shape, assembling into trimeric spike | |||
Several hydrophobic amino acids at the tip of this spike, colored bright red here, insert into the lysozomal membrane and cause the virus membrane to fuse with lysozome. | |||
