Dengue is also transmitted by mosquitoes and can spread from one person to another. The virus attacks white blood cells. It affects the body's immune system. High fever is accompanied by body pain. Pain behind the eyes also occurs. The patient may have headaches and breathing problems. Bleeding may occur from the nose and gums. Bleeding can kill a person.
