Dengue begins with very basic symptoms, such as fever and general malaise, which begin to appear about three days after the Aedes Aegypti mosquito bite . Because these signs are very common in other diseases, it is important to carefully monitor the evolution of the condition so that a misdiagnosis can not occur.
Dengue Symptoms and How They Appear
” The first symptoms of dengue are fever, usually high (over 38 ° C), with or without chills, severe myalgia (body pain), joint pain, retro-orbital pain (behind the eyes), headache and prostration, which is usually quite pronounced. Nausea, vomiting, diarrhea, rash (red spots on the skin) and bleeding may also occur, “says Dr. Diana Galvão.
As the specialist in infectious and parasitic diseases points out, these symptoms are caused by the intense stimulation of the immune system by the virus, with formation of antigen-antibody complex, activation of immune cells and production of inflammatory substances called cytokines. These cause fever and inflammation of the tissues, causing pain, swelling and, in more severe cases, vascular injury, loss of fluid and shock.
Treating the symptoms of dengue
The symptoms of dengue should be treated, according to the professional, with symptomatic medications, that is, treatment for pain and fever (which are the main symptoms) and other symptoms that are present. It is also recommended rest with withdrawal from work and oral or venous hydration, depending on the severity of the case.
The doctor points out that anti-inflammatory drugs and acetylsalicylic acid (“aspirin”) medications are contraindicated because of the risk of hemorrhagic complications. “Hydration (fluid replacement) is the most important component of treatment, because when done correctly and early prevents the hypovolemic shock of dengue, which is the major cause of death from this disease .”
