Dengue fever - symptoms, diagnosis, treatment, prevention Dengue fever is a viral infection carried by mosquitoes.  It is increasingly widespread around the world and is common in various travel destinations popular with Bangladesh, including South East Asia and the Pacific Islands.    Up to 400 million people are infected each year around the world, while in Bangladeshi there were 125 cases of dengue fever reported in 2015, all of which were contracted overseas. Transmission of the virus Dengue fever cannot be passed directly from one infected person to another. It is a mosquito-borne infection that requires a specific variety of mosquito (the “Aedes” mosquito) to pass it from person to person.  The mosquito transmits the virus by biting an infected individual then biting someone else.   The incubation period (the time between infection with the virus and appearance of signs and symptoms) is, on average, five to eight days. Signs and sym...

Fever Fever, also known as pyrexia and febrile response, is defined as having a temperature above the normal range due to an increase in the body's temperature set-point.There is not a single agreed-upon upper limit for normal temperature with sources using values between 37.5 and 38.3 °C (99.5 and 100.9 °F).The increase in set-point triggers increased muscle contractions and causes a feeling of cold.This results in greater heat production and efforts to conserve heat. When the set-point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure. This is more common in young children.Fevers do not typically go higher than 41 to 42 °C (105.8 to 107.6 °F). A fever can be caused by many medical conditions ranging from not serious to potentially serious. This includes viral, bacterial and parasitic infections such as the common cold, urinary tract infections, meningitis, malaria and appendicitis among...

Fever: Causes, symptoms, and treatments Fever (also known as pyrexia or controlled hyperthermia) is when a human's body temperature goes above the normal range of 36-37 Centigrade (98-100 Fahrenheit) - it is a common medical sign. As the individual's body temperature goes up, there may be a sensation of cold until the temperature levels off and stops rising. People's normal body temperatures may vary and are affected by factors such as eating, exercise, sleeping, and what time of the day it is. Our body temperature is usually at its highest at around 6 pm and at its lowest at about 3 am. An elevated body temperature (fever) is one of the ways our immune system attempts to combat an infection. Usually, the rise in body temperature helps the individual resolve an infection. However, sometimes it may rise too high, in which case, the fever can be serious and lead to complications. Doctors say that as long as the fever is mild, there is no need to bring it down - if...

Fever Fever facts Although a fever could be considered any body temperature above the normal 98.6 F (37 C), medically, a person is not considered to have a significant fever until the temperature is above 100.4 F (38.0 C). Most fever is beneficial, causes no problems, and helps the body fight off infections. The main reason to treat a fever is to increase comfort. Fever is the result of an immune response by your body to a foreign invader. Foreign invaders include viruses, bacteria, fungi, drugs, or other toxins. Children under 3 months of age with a temperature of 100.4 F (38.0 C) or greater should be seen by a health-care professional. They may be quite ill and not show any signs or symptoms besides a fever. Infants younger than 6 weeks of age should be seen immediately by their doctor. Acetaminophen (Tylenol and others) and ibuprofen (Advil, Motrin) can be used to treat a fever. Aspirin should not be used in children or adolescents to control fever. The prognos...
