Outbreaks of febrile illnesses compatible with dengue fever have been recorded throughout history, with the first epidemic described in 1635 in the West Indies. In 1779-1780, the first confirmed, reported outbreak of dengue fever occurred almost simultaneously in Asia, North America, and Africa.
Dengue viruses have been on the march for more than 100 years. Dengue originated in monkeys and spilled over into humans as long as 800 years ago. It was restricted to Africa and Southeast Asia until the mid-20th century.
Moreover, Where is dengue virus found?
Dengue fever is found throughout the world, but mainly occurs in tropical and subtropical areas. It is widespread in regions of Africa, Central and South America, the Caribbean, the Eastern Mediterranean, South and Southeast Asia, and Oceania.
Secondly, Can dengue be detected on first day of fever?
For patients presenting during the first week after fever onset, diagnostic testing should include a test for dengue virus (rRT-PCR or NS1) and IgM. For patients presenting >1 week after fever onset, IgM detection is most useful, although NS1 has been reported positive up to 12 days after fever onset (Figure 3-01).
Simply so, What is the history of dengue?
Dengue originated in monkeys and spilled over into humans as long as 800 years ago. It was restricted to Africa and Southeast Asia until the mid-20th century. The dengue viruses in viremic individuals and their Aedes aegypti mosquito vectors spread throughout tropical Southeast Asia via maritime shipments.
When did Dengue start?

The disease is common in many popular tourist destinations in the Caribbean (including Puerto Rico), Central and South America, Southeast Asia, and the Pacific Islands. In the United States, local cases and limited spread of dengue does occur periodically in some states with hot, humid climates and Aedes mosquitoes.
How does the dengue virus attack the body?
In severe infection, the virus production inside the body is greatly increased, and many more organs (such as the liver and the bone marrow) can be affected. Fluid from the bloodstream leaks through the wall of small blood vessels into body cavities due to capillary permeability.
Is dengue fever found in the United States?
Dengue outbreaks occasionally occur in the continental United States. Dengue is common in the US territories of Puerto Rico, the US Virgin Islands, and American Samoa. Nearly all dengue cases reported in the 48 contiguous US states were in travelers infected elsewhere.
How is dengue created?
The dengue virus is spread through a human-to-mosquito-to-human cycle of transmission (Figure 2). Typically, four days after being bit by an infected Aedes aegypti mosquito, a person will develop viremia, a condition in which there is a high level of the dengue virus in the blood.

When was the dengue virus first discovered?
In 1943, Ren Kimura and Susumu Hotta first isolated the dengue virus. These two scientists were studying blood samples of patients taken during the 1943 dengue epidemic in Nagasaki, Japan. A year later, Albert B. Sabin and Walter Schlesinger independently isolated the dengue virus.
In which season Dengue is more common?
Dengue fever happens most often in urban areas. But it may be found in rural areas. The mosquitoes that carry the virus usually pass it on during and shortly after the rainy season. The mosquitoes are most active during the day.
How do you confirm dengue?
Serologic tests Later in the illness (≥4 days after fever onset), IgM against dengue virus can be detected with MAC-ELISA. For patients presenting during the first week after fever onset, diagnostic testing should include a test for dengue virus (rRT-PCR or NS1) and IgM.
