Which mosquito is good for dengue fever?
Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. These mosquitoes also spread Zika, chikungunya, and other viruses.
Which insect carries the parasite of dengue?
The Aedes aegypti mosquito is the main vector that transmits the virus that causes dengue. The virus is passed to humans through the bites of an infective female Aedes mosquito, which mainly acquires the virus while feeding on the blood of an infected person.
Which insect causes malaria and dengue?
Malaria is caused by a female mosquito, Anopheles; while dengue is caused by Aedes aegypti mosquito. In the past, the presence of a co-infection in an individual is sporadically reported [1, 2]. Both of the diseases cause an acute pyrexial illness; however, only malaria can cause a chronic fever.
Which Aedes mosquito causes dengue?
Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zika viruses.
How much platelet count is normal in dengue?
The normal platelet count in the body ranges from 1.5 to 4 lacs, this can go down to as low as 20,000 to 40,000 in the case of dengue patients. This happens because: Dengue can damage your bone marrow, the platelet-producing centre of the body.
Is one mosquito bite enough for dengue?
With dengue, it is said that the infected mosquitoes target body parts like around the ankles, elbows. It should also be remembered that a single bite of the mosquito is enough to infect an individual and span across symptoms.
How is malaria different from dengue?
A key differentiation is that malaria is an infectious disease caused by a parasite, while dengue is a viral infection. Malaria is transmitted only by female Anopheles mosquitoes because they depend on blood meals for egg production.
Why do mosquitoes carry dengue?
After a mosquito feeds on the blood of someone infected with the dengue virus, that mosquito becomes a dengue vector. The mosquito must take its blood meal during the period of viremia, when the infected person has high levels of the dengue virus in the blood.
Is dengue worse than malaria?
Estimates by the WHO suggest that cases of Malaria-related deaths have grown to more than 435,000 people annually while Dengue has been identified as one of the most dangerous and fastest spreading mosquito-borne viral diseases in the world.
Is malaria and dengue same?
Will I get dengue if bitten by Aedes?
Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus). These are the same types of mosquitoes that spread Zika and chikungunya viruses.
How fast does platelet count drop in dengue?
The platelet counts drop below normal level (150,000–450,000 platelets/μL) and may reach as low as <40000 platelets/μL during day 3–7 of fever in many patients6.
What is dengue hemorrhagic fever (DHF)?
Dengue hemorrhagic fever (DHF) is a serious complication of infection with the mosquito-borne dengue fever virus, and is more likely to follow a primary dengue infection in pregnant than in nonpregnant women.
Does antibody-dependent enhancement enhance dengue virus replication?
Thus, it is hypothesized that prior infection, through a process known as antibody-dependent enhancement (ADE), enhances the infection and replication of dengue virus in cells of the mononuclear cell lineage (15, 62, 66, 67, 106).
What are the signs and symptoms of dengue reinfection?
A similar syndrome is seen in mice with persistent infections with LCMV. Dengue hemorrhagic fever (Chapter 389) and dengue shock syndrome are forms of dengue reinfection characterized by capillary leakage and hemorrhage.
How is MacMac-ELISA used in the diagnosis of dengue?
MAC-ELISA has become an invaluable tool for surveillance of dengue, DHF, and DSS. In areas where dengue is not endemic, it can be used in clinical surveillance for viral illness or for random, population-based serosurveys, with the certainty that any positive results detected indicate recent infections (within the last 2 to 3 months).
