SEVILLE, spain – Andalusian authorities are intensifying their campaign against the West Nile virus (WNV), also known as West Nile Fever, following a concerning rise in human cases. The virus, transmitted by mosquitoes, was first detected in the region in 2013. Years 2020 and 2024 saw the highest numbers of infections.
In 2020,officials recorded 73 cases,including six fatalities. The number surged to 106 in 2024, with Seville province accounting for 93 of those cases.
New Measures Announced to Enhance Surveillance and control
On March 6, the Ministry of Health and Consumption of the Junta de andalucía, under the General Directorate of Public Health, unveiled a series of enhanced measures aimed at improving WNV control and minimizing its impact. Rocío Hernández, the Minister of Health, presented these initiatives to the Parliament of Andalusia.
The core of the strategy involves a more rigorous “surveillance and control” system, acknowledging the elevated risk, according to the ministry. These improvements are integrated into the region’s Vector Surveillance and Control Program.
Simplified Risk Classification and Increased Municipal Support
A key change is the simplification of the risk classification system for Andalusian municipalities. The system now uses three levels: low, medium, and high. This streamlined approach is designed to facilitate a quicker,more tailored response based on the severity of the situation in each locality.
The Board has also increased assistance to municipalities, ensuring local authorities have the resources needed to implement preventive measures.
Introduction of ‘Area in Alert’ Designation
Authorities are introducing the concept of an “area in alert.” This temporary designation will be activated when there is evidence of the virus near population centers,within a 1.5-kilometer radius.
Additionally, the predictive model developed by CSIC Doñana will be optimized to improve forecasts of virus expansion, enabling more effective interventions.
Extended Monitoring and Increased Trapping
The annual duration of preventative measures has been extended, with winter traps now deployed into the spring to capture mosquitoes and animals that transmit WNV.The number of traps per province will increase from 27 to 120 in 2025.
Health promotion efforts in high-risk municipalities will be bolstered, and a second reference laboratory will be established at the Virgen del rocío University Hospital to expedite diagnosis and treatment. This will supplement the existing laboratory at the virgen de las nieves University Hospital.
Enhanced Coordination Between Administrations
The program emphasizes greater coordination between government bodies.Health agents will conduct visits to affected municipalities, and a preparation table has been established as winter, involving approximately 400 public health agents.
This team is crucial for ensuring the proper implementation of preventive actions and providing guidance to affected municipalities.
Continuous Betterment, Not Just Emergency Response
Ulises Ameyugo, deputy director of Health Protection of the Junta de Andalucía, clarified that the activation of the 400 agents in April is part of a continuous improvement strategy, not a reaction to a surge in cases.
Ameyugo stated that the program modifications were based on feedback from stakeholders on areas for improvement. “It is indeed not an emergency measure,” Ameyugo said. “We had the emergency measure in 2020, when there was no program.”
He added that the timing of the activation is due to the peak mosquito activity period, which runs from June to October.
Predictive Model Received in january
Ameyugo also noted that the predictive model from CSIC Doñana, which informed the program’s improvements, was received in january. The model was then compared with the help of experts from the Junta de Andalucía, and the revised program was launched in March.
Letters were sent to the municipalities,and time was allotted for responses before the agents were deployed in april.
No Municipality is Immune
Ameyugo emphasized that “no municipality of Andalusia is free to have the fever of the western Nile,” highlighting the importance of ongoing protection efforts. Agents will receive additional training in June, coinciding with the start of the mosquito season, to ensure the effectiveness of prevention actions.
Public Awareness Campaign
A dialog plan has been developed to inform the public about the risks and preventive measures related to WNV. This strategy aims to raise awareness and encourage citizen collaboration in prevention efforts.
Ameyugo stated that the 400 agents will also receive training in communication to actively participate in this public awareness campaign.With these new measures, Andalusia aims to improve WNV control and mitigate the effects of the disease in the coming years.
Andalusia’s Fight Against West Nile Virus: Your Questions Answered
The West Nile Virus (WNV), transmitted by mosquitoes, has prompted Andalusian authorities to intensify their efforts. This guide provides a comprehensive overview of the situation, answering your key questions about the new control measures and prevention strategies.
What is the West Nile Virus (WNV)?
The West Nile Virus, also known as West Nile Fever, is transmitted to humans through the bite of an infected mosquito. The virus first appeared in Andalusia in 2013.
Why is Andalusia taking new action against WNV?
Following a concerning rise in human cases, with 2020 and 2024 showing the highest infection numbers. In 2020, there were 73 cases and 6 fatalities. The number surged to 106 cases in 2024, with the Seville province being most affected.
What new measures are being implemented?
- Simplified Risk Classification: A new three-level system (low, medium, high) helps facilitate a quicker, more tailored response to outbreaks.
- Increased Municipal Support: Increased resources and assistance given to local authorities for preventative measures.
- ‘Area in Alert’ Designation: temporary designation of areas near population centers (within a 1.5-kilometer radius) with evidence of the virus.
- Optimized Predictive Modeling: Using enhanced predictive models from CSIC Doñana to forecast virus expansion.
- Extended Monitoring & Trapping: Winter traps deployed into spring & increased trap numbers from 27 to 120 per province by 2025.
- Enhanced Coordination: Increased collaboration among government bodies. Health agents will visit affected municipalities.
- Public Awareness Campaign: Increased educational efforts and better interaction regarding WNV risks and prevention.
What is the ‘Area in Alert’ Designation?
This temporary designation is activated when the virus is detected near population centers (within a 1.5-kilometer radius). It allows authorities to focus resources and implement targeted interventions.
How will the predictive model improve WNV control?
The predictive model, developed by CSIC Doñana, is being enhanced to improve forecasts of virus expansion. This will allow for more effective intervention strategies, resource allocation, and a more proactive approach to preventing outbreaks.
What are the key features of the extended monitoring strategy?
- The annual duration of preventative measures has been extended, with winter traps now deployed into the spring to capture mosquitoes and animals that transmit WNV.
- The number of traps per province will increase from 27 to 120 in 2025.
- Enhanced health promotion efforts in high-risk municipalities.
- A second reference laboratory will be established at the Virgen del Rocío University Hospital to expedite diagnosis and treatment, supplementing the existing laboratory at the Virgen de las Nieves University Hospital.
how is coordination between different administrations being enhanced?
There are several measures being put in place to enhance inter-governmental collaboration:
- Health agents will visit affected municipalities.
- A planning table has been established to help prevent measures.
- Approximately 400 public health agents in charge of prevention actions.
Why is this program being described as a continuous improvement strategy rather than a reaction to a surge in cases?
Ulises Ameyugo,deputy director of Health Protection of the Junta de Andalucía,clarified that the activation of the 400 agents in April is part of a continuous improvement strategy,not a reaction to a surge in cases
