Type 1 Excludes

dengue hemorrhagic fever (A91)

Clinical Information

Acute infectious, eruptive, febrile disease caused by four

antigenically related but distinct serotypes of the dengue

virus; transmitted by the bite of infected aedes mosquitoes,

especially a. Aegypti; classical dengue (dengue fever) is

self-limiting and characterized by fever, myalgia, headache,

and rash; dengue hemorrhagic fever is a more virulent form of

dengue virus infection.

An acute febrile disease transmitted by the bite of aedes

mosquitoes infected with dengue virus. It is self-limiting

and characterized by fever, myalgia, headache, and rash.

Dengue hemorrhagic fever is a more virulent form of dengue.

An acute infection caused by dengue virus. Signs and symptoms

include sudden onset of fever, headache, rash, arthralgia,

and myalgia. It is transmitted through mosquitoes.

An acute, infectious tropical disease caused by an

arbovirus transmitted by mosquitoes

Dengue is an infectious disease caused by a virus.

You can get it if an infected mosquito bites you. It is

common in warm, wet areas of the world. Outbreaks occur in

the rainy season. Dengue is rare in the United States.

Symptoms include a high fever, headaches, joint and muscle

pain, vomiting and a rash. Most people with dengue recover

within 2 weeks. Until then, drinking lots of fluids, resting

and taking non-aspirin fever-reducing medicines might help.

Sometimes dengue turns into dengue hemorrhagic fever, which

causes bleeding from your nose, gums or under your skin. It

can also become dengue shock syndrome, which causes massive

bleeding and shock. These forms of dengue are life-threatening.

to lower your risk when traveling in dengue-prone countries

wear insect repellent with deet

wear clothes that cover your arms, legs and feet

close unscreened doors and windows


Dengue hemorrhagic fever A91- >


Clinical Information

A serious condition caused by dengue virus infection. Patients

present with an acute febrile illness followed by restlessness,

irritability, and bleeding. It may lead to hemorrhagic shock

and death.

A virulent form of dengue characterized by thrombocytopenia

and an increase in vascular permeability (grades i and ii)

and distinguished by a positive pain test (e.g., tourniquet

pain test). When accompanied by shock (grades iii and iv),

it is called dengue shock syndrome.

Applicable To

Arboviral fever NOS

Arbovirus infection NOS

Clinical Information

Infections caused by arthropod-borne viruses, general

or unspecified.


Yellow fever A95- >


Clinical Information

A disease caused by infection with the yellow fever virus, which

is carried by mosquitos. Symptoms include body aches,

chills, fever, severe headache, weakness, and a yellow skin

color. Bleeding, vomiting, and failure of the liver and other

organs may occur in late stages of the disease.

A tropical disease transmitted by mosquito bites

A viral infection caused by a flavivirus called yellow fever

virus. It is transmitted to humans from infected mosquitoes.

The signs and symptoms range from a mild febrile illness to

liver damage with jaundice and hemorrhages.

Acute infectious disease primarily of the tropics, caused

by a flavivirus and transmitted to humans by mosquito vectors.

An acute infectious disease primarily of the tropics, caused

by a virus and transmitted to man by mosquitoes of the genera

aedes and haemagogus.


Unspecified viral hemorrhagic fever A99- >


Clinical Information

A group of viral diseases of diverse etiology but having

many similar clinical characteristics; increased capillary

permeability, leukopenia, and thrombocytopenia are common

to all. Hemorrhagic fevers are characterized by sudden

onset, fever, headache, generalized myalgia, backache,

conjunctivitis, and severe prostration, followed by various

hemorrhagic symptoms. Hemorrhagic fever with kidney

involvement is hemorrhagic fever with renal syndrome.

Syndrome that occurs in perhaps 20-40 percent of infections

by a number of different viruses of the families arenaviridae,

bunyaviridae, flaviviridae, filoviridae, etc; some types of

hemorrhagic fever are tick borne, others mosquito borne,

and some seem to be zoonoses; clinical manifestations are

high fever, scattered petechiae, gastrointestinal tract and

other organ bleeding, hypotension, and shock; kidney damage

may be severe and neurologic signs may appear.

Viral hemorrhagic fevers (vhfs) are a group of illnesses

caused by four families of viruses. These include the ebola

and marburg viruses and lassa fever virus. Vhfs have common

features: they affect many organs, they damage the blood

vessels and they affect the body's ability to regulate itself.

Some vhfs cause mild disease, but some, like ebola or marburg,

cause severe disease and death.vhfs are found around the world.

Specific diseases are usually limited to areas where the animals

that carry them live. For example, lassa fever is limited to

rural areas of west africa where rats and mice carry the virus.

the risk for travelers is low, but you should avoid visiting

areas where there are disease outbreaks. Because there are no

effective treatments for some of these viral infections, there

is concern about their use in bioterrorism.
