The threat posed by Zika virus infection highlights the need to reinforce preparedness arrangements for mosquito-borne diseases in EU/EEA countries, especially for pathogens transmitted by Aedes aegypti and Aedes albopictus.
The aim of this document is to highlight measures that can effectively red...uce the risk of importation and local transmission of pathogens transmitted by Ae. aegypti and Ae. albopictus. The main diseases of concern in this context are Zika, dengue, chikungunya and yellow fever.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr...evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

Target Malaria is an innovative project that aims to reduce the population of mosquitoes that transmit malaria in sub-Saharan Africa, thereby decreasing disease transmission. As part of its work to combat malaria, Target Malaria has started contained studies at the Uganda Virus Research Institute (U...VRI) in Uganda.

Diagram of the malaria lifecycle, including mosquito, human liver, and human blood stages. The diagram also illustrates infective vs diagnostic stages of the parasite's lifecycle. Also included are the temporal views of both p. falciparum and p. vivax.
The malaria parasite develops both in humans and in the female Anopheles mosquitoes. The size and genetic complexity of the parasite mean that each infection presents thousands of antigens (proteins) to the human immune system.
A chronological map of the presence of Zika only in those countries for which there is evidence of indigenous transmission by mosquitos, excluding the many countries that have notified imported Zika infections.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

This WHO video presents updated recommendations on two new types of insecticide-treated nets (ITNs) designed to combat mosquito resistance: nets containing either pyrethroid and chlorfenapyr or pyrethroid and pyriproxyfen. The video highlights the improved effectiveness of these nets compared to sta...ndard nets and emphasises the importance of their universal use in malaria-endemic areas, particularly for pregnant women and young children where supplies are limited.

Older children play a crucial role in preventing malaria by encouraging the use of insecticide-treated bed nets and preventing mosquito breeding. They also support younger children during illness by assisting with nutrition and recovery activities. Recent advancements include the introduction of a m...alaria vaccine in some regions. Educational initiatives empower children to learn, create and share key malaria messages through storytelling, posters and campaigns, thereby fostering community awareness and action.

This infographic from the Tropeninstitut illustrates the malaria transmission cycle. It begins when an Anopheles mosquito bites a human and injects its sporozoites into the bloodstream. The sporozoites then travel to the liver where they mature and release merozoites back into the bloodstream. The m...erozoites then infect red blood cells, resulting in the clinical symptoms of malaria. Some merozoites develop into gametocytes, which can be ingested by another mosquito when it bites the infected person again, thus continuing the transmission cycle.
The infographic serves as an educational tool, helping to explain the complex life cycle of the malaria parasite and the role of mosquitoes in spreading the disease.

In the battle against diseases like Zika and dengue, knowledge is power. Climate change is shifting the
distribution of mosquitoes and to new areas. Empowering communities is essential in reaching and pro-
tecting the most vulnerable individuals and households. Vector control programmes, community... empow-
erment and awareness campaigns are proven strategies to reduce the burden of vector-borne diseases.
Red Cross and Red Crescent volunteers can play a key role in community and school outreach activities for Zika, dengue and chikungunya prevention. These community-based activities need to be sustained to
ensure long-lasting disease control.

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.
