Lymphatic filariasis is a neglected tropical disease that can cause permanent disability through disruption of the lymphatic system. This disease is caused by parasitic filarial worms that are transmitted by mosquitos. Mass drug administration (MDA) of antihelmintics is recommended by WHO to elimina...te lymphatic filariasis as a public health problem. This study aims to produce the first geospatial estimates of the global prevalence of lymphatic filariasis infection over time, to quantify progress towards elimination, and to identify geographical variation in distribution of infection.

Lymphatic filariasis (LF) is a preventable neglected tropical disease (NTD) caused by infection with the filarial parasites Wuchereria bancrofti, Brugia malayi or B. timori. Mosquitos in the genera Culex, Anopheles, Mansonia and Aedes transmit the parasites from person to person. Lymphoedema and hyd...rocoele are the visible, chronic clinical consequences of the impairment of lymphatic vessels caused by infection with these parasites. WHO established the Global Programme to Eliminate Lymphatic Filariasis (GPELF) to stop transmission of infection by mass drug administration (MDA) of anthelminthics and to alleviate the suffering of people affected by the disease through morbidity management and disability prevention (MMDP). Since the start of GPELF, the number of infections has been reduced by 74% globally. The latest estimate is that 51.4 million people are infected.

Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection occurs when filarial parasites are transmitted to humans through mosquitoes. Infection is usually acquired in childhood causing hidden damage to the lymphatic system.

Updated 6 September 2016. This guidance has been developed to provide advice on the prevention of potential sexual transmission of Zika virus. The primary transmission route of Zika virus is via the Aedes mosquito. However, sexual transmission of Zika virus may also be possible, with limited evidenc...e recorded in a few cases. This is of concern due to an association between Zika virus infection and potential complications, including microcephaly and Guillain-Barré syndrome.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

This 3 minutes and 24 second animation describes Dengue transmission, infection and the different symptoms associated with this disease. Also, the animation gives additional information about the habits of this mosquito. This video illustrates several important preventative measures, both inside the... house and the environmental sanitation around the house, to avoid being bitten by the mosquitoes. Let's all work together to stop the spread of dengue!

Arbovirus (arthropod-borne virus) is defined as any virus that is transmitted to humans and/or other vertebrates by certain species of blood-feeding arthropods, mostly insects (flies and mosquitoes) and arachnids (ticks). Arbovirus is a descriptive term based on transmission by vectors with particul...ar characteristics. It is not part of the International Committee on Taxonomy of Viruses classification of viruses (ie, it is not a species, genus, or family), which is based on the nature and structure of the viral genome

The World Health Organization's malaria fact sheet provides an overview of malaria, a life-threatening disease caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes. It highlights that malaria is preventable and curable, yet remains a significant glo...bal health challenge. Key statistics from 2023 indicate an estimated 263 million malaria cases and 597,000 deaths worldwide, with the WHO African Region bearing the majority of this burden. The fact sheet details transmission methods, symptoms, at-risk populations, diagnostic approaches, treatment options—including the use of artemisinin-based combination therapies (ACTs)—and preventive measures such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS). It also discusses the impact of malaria on vulnerable groups like children under five and pregnant women, and outlines WHO's global response strategies aimed at reducing malaria incidence and mortality rates.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

Health communication has proven to play a crucial role in addressing diseases such as dengue, Zika and chikungunya, for which there are no definitive or easily accessible vaccines. In this context, this discipline becomes a fundamental tool to promote the change behavior and promote preventive pract...ices that reduce the transmission of these diseases. By not having a definitive medical solution, accurate and timely information, effectively disseminated through educational campaigns, media and communication channels public health, can significantly influence individual and community actions to control the spread of these mosquito-borne viruses. The accumulated research around the threat of the aforementioned arboviral diseases brings together a series of recommendations around specific communication activities, such as disseminating timely and accurate information that integrates public health concerns and the needs of information of the population, especially vulnerable groups such as women of childbearing age, pregnant women and health workers.
