In 2022, a total of 6,131 confirmed malaria cases were reported across the EU/EEA. Of these, 5,375 had a known importation status and nearly all (99.8%) were travel-related. Only 13 infections were acquired within Europe, with seven occurring in France, three in Germany, two in Spain and one in Irel

and. A distinct seasonal peak was observed from July to September, reflecting travel to malaria-endemic regions. Notification rates were higher among men than women, with a male-to-female ratio of 2:1. France reported the highest number of cases, followed by Germany, Spain, Italy and Belgium. After dropping sharply in 2020 due to travel restrictions imposed during the pandemic, overall notification rates increased again in 2021 and 2022, reaching 0.8 cases per 100,000 people. These findings emphasise that malaria in Europe is predominantly an imported disease closely linked to international travel, with sporadic local transmission being rare.

We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by rese
...
archers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges, supporting a cost-effective IVS strategy for early warning of CL outbreaks through an environmental modification alert network, which includes multiple sources of information and actors. In relation to VL, the earliest colonization sites and spatial distribution were explained by modeling and forecasting the most likely hotspots, persistent in time and space, and modulated by environmental variables. Therefore, for VL, a scalar strategy of critical site selection is proposed from a “city” scale based on secondary sources such as remote sensing for the definition of possible areas to monitor and intervene, a scale of restriction from possible to most likely areas through local knowledge, and a “focal site” scale of trap placement through field observation; in this way, IVS activities are carried out at a few sites of the urban landscape and allow a sustainable program.

The document outlines steps for managing data at different levels (local, regional, national), analysing disease trends by time, place, and person, and using indicators to monitor outbreak risks. It also provides methods for interpreting and communicating results clearly to decision-makers to support effective health interventions in emergencies.

The report provides an epidemiological update on cholera outbreaks in Haiti as of January 17, 2023. Since the first confirmed cases in October 2022, Haiti has reported 24,232 suspected cases, including 1,742 confirmed cases and 483 deaths. The most

affected areas are in the Ouest Department, particularly Port-au-Prince. Children aged 1 to 4 years are the most affected group. The ongoing humanitarian crisis, security issues, and limited access to healthcare have worsened the outbreak, hindering epidemiological surveillance and case reporting. The PAHO/WHO is working with Haitian authorities to respond to the outbreak and mitigate its spread.
