WHAT IS DENGUE FEVER ????????
Dengue is an infectious disease caused by dengue viruses, which are transmitted to humans by mosquitoes. The rising level of dengue infections has become a serious international concern. When was dengue first reported, and how was the disease named? What are the symptoms of dengue? Is there a cure? In this section, we will explore the answers to these questions
What Are the Symptoms of Dengue Fever???????
Doctors often have trouble diagnosing dengue because its symptoms can vary widely. Some patients show no symptoms at all. Babies and young children infected with the dengue virus typically have mild symptoms such as a fever and a rash over their entire bodies, but no other symptoms of dengue. Older children and adults may also have these mild symptoms, or they may have classic symptoms of dengue, including a high fever that lasts for two to seven days, severe pain in the muscles, bones, and joints, pain behind the eyes, severe headaches, nausea and vomiting, and a rash. Dengue fever is characterized by a fever response with two peaks. Near the beginning of the infection, the patient experiences a very high body temperature, which then starts to drop and suddenly climbs again for a second time.
Other symptoms of dengue fever include a decrease in the number of white blood cells and a low level of platelets in the blood. Patients with dengue fever may have skin hemorrhages (bleeding under the surface of the skin) that appear as red or purple spots on the body. Dengue fever can also cause bleeding from the skin, nose, and gums. Recovery from dengue fever is often lengthy, lasting several weeks, and patients can experience lingering fatigue and depression
