What are the stages of dengue fever?

Answer 1

They can be classified into four as with the different virus serotypes or depending on the severity. Dengue fever is described as being milder with flu-like symptoms at first then having the "triad" of fever,rash and headache. Dengue Hemorrhagic Fever(DHF) or Dengue Shock Syndrome(DSS) is the more severe form, wherein a person at some time had the virus and is reinfected.This presents with small purplish spots in the skin where blood is leaking and internal bleeding as well.
there are 4 types of dengue

Answer 2

Stage 1: Acute fever and upper respiratory symptoms

· Stage 2: Fever subsides

· Stage 3: Circulatory failure, neurological problems, and hemorrhaging

· Stage 4: Shock and death (10% of all cases reach this stage)

Answer 4

There are four types of dengue fever

Dengue fever can be caused by any one of four types of dengue virus:

DEN-1,

DEN-2,

DEN-3, and

DEN-4.

A person can be infected by at least two, if not all four types at different times during a life span, but only once by the same type.

Answer 5

Four types of malaria are known to infect a person:

1. Plasmodium vivax (P.v.): It has the widest distribution around the globe. Approximately 60% of infections in India are caused by P.v. Although it seldom causes death or other serious problems, it can still cause major illness. Some of the common symptoms of P.v are fatigue, diarrhoea, bouts of fever and chills. Flu-like symptoms are commonly observed in the person affected by plasmodium vivax.
2. Plasmodium ovale (P.o): This is the rarest of all the malaria types and is mostly found in Ghana, Liberia, Nigeria and the tropical West African region. Plasmodium ovale reoccurs in some cases because the parasite can rest in the liver of a patient for a few months to 4 years after getting infected by the mosquito carrying malaria. These parasites are most likely to relapse and invade RBCs and making the patient sick again.
3. Plasmodium malariae (P.m): This type of malaria is not as wide spread as the other types and is known to have less than 1 percent infections in the Indian subcontinent. The tropical and subtropical regions of South and Central America, South East Asia and Africa are witnessing its affects since long. Although it is not lethal, it still has varied distributions and is ranked third in prevalence. It manifests itself in the form of high fever and chills.
4. Plasmodium falciparum (P.f): The plasmodium parasite is recognised as the most lethal parasite that causes most infections and deaths related to malaria. This type of malaria is found in Africa, South America, and South East Asia. A Study held in 2002 showed that about 2.2 billion people in the world were at risk of getting affected by P.f. 25% of these events occurred in South East Asian region and almost 70% in Africa. The individual infected by this parasite experiences fatigue, dizziness, abdominal pain, aching muscles, enlarged spleen, seizures, sore back, joint pain, vomiting, nausea, fever, headache, anaemia and some neurological symptoms as well. Since it is the severest of all the four malaria types, it become important that this be checked, diagnosed and treated on time. This infection also has an adverse affect on brain and the central nervous system. Many times, changes in the levels of consciousness, paralysis and convulsions can also occur.

Malaria fever affects almost 500 million every year and about 1 to 3 million people face death. It is also critical for those travelling to these regions where the hold of malaria is strong and old. This makes prevention of malaria even more crucial.

Answer 6

Dengue is an acute viral disease caused by any of the four dengue virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4). The principal mosquito vector is Aedes aegypti. This disease is sometimes called "bone break" fever because of the tremendous chills and shaking the patient has. All four virus serotypes produce a similar illness which gives lifelong immunity to THAT specific serotype. A small proportion of infected persons may develop the severe form of disease, dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). A person can be infected with another one of the serotypes at another time.

Answer 7

It has been called breakbone fever because of the severe bone and joint pain it causes.
