Summary:

  • Dengue cases are expected in Lisbon due to the presence of Aedes albopictus mosquitoes.

  • The CEVDI is the national laboratory for studying vector-borne diseases.

  • The Aedes aegypti mosquito, a primary dengue carrier, is absent in mainland Portugal.

  • Globalization and climate change are increasing the risks of mosquito-borne diseases.

  • Public participation through the MosquitoAlert app is vital for monitoring mosquito populations.

Exploring the Threat of Dengue in Portugal

At the Center for Vector Studies and Infectious Diseases (CEVDI) in Palmela, researchers are closely monitoring the lifecycle of mosquitoes, including the infamous Aedes albopictus, known as the Asian tiger mosquito. The CEVDI is the national reference laboratory for diagnosing diseases such as dengue, zika, and chikungunya. Recent findings have confirmed the presence of this mosquito species in areas like Cascais and Pombal, raising alarms about potential dengue cases in Lisbon.

Mosquito Research at CEVDI

The Mosquito Dilemma

Maria João Alves, a researcher at the CEVDI, emphasizes that while the presence of the Aedes albopictus mosquito is concerning, it will take time for dengue cases to occur. The disease can only be transmitted if mosquitoes are abundant and if they bite infected individuals.

  • Aedes aegypti, the primary vector for dengue, is not present in mainland Portugal, but Aedes albopictus has been detected, prompting increased vigilance.

Historical Context

The CEVDI has roots dating back to 1938 when it was established to combat malaria in the region. Due to its strategic location, Marateca was chosen for the institute, which played a crucial role in eradicating malaria in Portugal.

Globalization and Climate Change: Key Factors

The rise of vector-borne diseases is closely linked to globalization and climate change. As cities grow and people travel, the risk of introducing these diseases increases. Maria João Alves points out that urbanization facilitates the spread of diseases like dengue, which thrive in densely populated areas.

Community Involvement in Science

Public awareness and participation are crucial. The MosquitoAlert app allows citizens to report mosquito sightings, aiding scientific research and tracking.

Community Participation

As the situation develops, the CEVDI remains vigilant in monitoring mosquito populations and educating the public on preventive measures against mosquito bites and potential disease transmission.
