General Situation Report on Bolivia
Currently, most of Bolivia is being affected by heavy rainfalls and by floods due to El Niño. Flooding is expected to continue, given the heavy precipitation that has been affecting the country since the end of 2006.
Reports indicate that a total of 18,516 families have been affected (in the provinces of Cercado, Marbán, Moxos, Itenez, Ballivián, Vaca Diez and Yacuma) and that the Mamore River is rising at a rate of 14–16 cm daily in the town of Santa Ana. It is feared that families will suffer heavy damages, as has been the case to date with 1,200 of the 17,000 families residing there.
Prevention and Control Activities Underway
A meeting was held with Dr. César Reyes, Dr. Nyla Heredia, Minister of Health and Sports, and Dr. Nogales, Vice Minister of Health. A report was presented on the Situation Room and on activities currently being carried out:
- A second fumigation campaign.
- A vaccination campaign for yellow fever.
- Fumigation of all boats and vehicles coming from Santa Cruz.
- A refresher course held for medical staff in Trinidad (El Beni province) on clinical management of dengue cases; a total of 35 professionals attended the day-long session held on 23 February 2007, led by Dr. Carlos La Fuente.
Preparation of the Strategy of Integrated Management for the Prevention and Control of Dengue in Bolivia
At present, the National Dengue Plan will incorporate the Strategy of Integrated Management for the Prevention and Control of Dengue (EGI-Dengue). By the end of first semester 2007, a sound technical document will have been produced, with the following aspects:
- to serve as a standard guidebook for the roll-up of prevention and control activities; and
- strengthen the capacities of the health sector to promote new extra-sectoral associations and methodologies for behavioral changes in controlling vector breeding sites, thus
- making activities in the fight against dengue more sustainable and effective.
During the week of 19–24 March 2007, a workshop will be held to reinforce COMBI (Communication for Behavioral Impact). Dr. Linda Lloyd, in her capacity as PAHO/WHO Temporary Adviser and expert in the area of Mass Communication, will conduct the workshop.
