Africa: Mosquitoes - the Devastating Impact On Global Health

[Malaria Consortium] On World Mosquito Day, Malaria Consortium calls for the international community to reflect on the devasting impact the mosquito has on global health. In 2018, there were over 228 million malaria cases throughout the world and a global death toll of 405,000. But mosquitoes are responsible for transmitting more than just malaria - from zika virus to yellow fever, dengue, chikungunya, Japanese encephalitis and many more - collectively adding another 500 million cases of people burdened with febrile disease ea

Abstract Mosquitoes are principal vector of several vector-borne diseases affecting human beings leading to thousands of deaths per year and responsible for transmitting diseases like malaria, dengue, chikungunya, yellow fever, Zika virus, Japanese encephalitis, and lymphatic filariasis. In the present study, we evaluated the different solvent extracts of mangrove Avicennia marina for their toxicity against larvae of three major mosquito vectors, as well as selected microbial pathogens. The larvicidal mortality of third instars was observed after 24 h. Highest larval mortality was found for the acetone extrac...

Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...

Date: August 26, 2019 Issue #:  1579Summary:  Use of insect repellents is strongly recommended by the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) to prevent infections transmitted by mosquitoes and ticks. Insect repellents applied to exposed skin should be used in conjunction with other preventive measures such as wearing pants and long-sleeved shirts, and avoiding outdoor activities during peak mosquito-biting times. Mosquitoes can transmit Zika, chikungunya, dengue, West Nile, eastern equine encephalitis, and yellow fever viruses, as well as...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

In this study, we were able to demonstrate that our measure for mosquito-borne viral suitability is informative in the context of Myanmar, despite the lack of ento-epidemiological datasets with high spatio-temporal resolution. By estimating suitability through climate variables and known ento-epidemiological parameters, we were able to project mosquito-born virus (MBV) suitability at the district level, a resolution for which epidemiological data and mosquito abundance measures are not generally available. Here, we discuss the national and subnational public health and control implications for MBVs in the context of our pr...

Abstract Mosquito-borne diseases have become more common as previously geographically isolated diseases have spread globally. Chikungunya, dengue, Japanese encephalitis, malaria, West Nile, yellow fever, and Zika are a few of the common and emerging viral diseases spread by mosquitoes. A thorough patient history, physical, and knowledge of diagnostic testing based on symptom duration is important to make a quick and accurate diagnosis. Because the treatment for many of these diseases is supportive, the emphasis is on reducing risk and spread of infection. PMID: 30115330 [PubMed - in process]

AbstractMosquitos are responsible for a number of protozoal and viral diseases. Malaria, dengue, Japanese encephalitis (JE) and chikungunya epidemics occur commonly all over the world, leading to marked mortality and morbidity in children. Zika, Yellow fever and West Nile fever are others requiring prevention. Environmental control and mosquito bite prevention are useful in decreasing the burden of disease but vaccination has been found to be most cost-effective and is the need of the hour. RTS,S/AS01 vaccine is the first malaria vaccine being licensed for use againstP. falciparum malaria. Dengvaxia (CYD-TDV) against dengu...
