Macau (MNA) – The districts of St. Lawrence and Fai Chi Kei on the Macau Peninsula registered the highest index rates of mosquito propagation (‘Ovitrap’) in August, at 67 per cent and 64.6 per cent, respectively.
According to data released by the Health Bureau (SS) on Monday evening, the overall city’s Ovitrap Index reached 58.4 per cent, similar to that registered in the same period a year ago and marginally lower vis-à-vis the 65.1 per cent recorded in July.
Excluding Macau Peninsula, the highest rate was found in Coloane at 56.3 per cent.
The SS also claimed that the rate in August was similar to the same periods since 2002.
Ovitrap is a vector surveillance mechanism which measures the number of mosquito egg clusters.
The index is commonly used to monitor Aedes aegypti density, determining factors related to dengue transmission in order to target areas and seasons for vector control, according to the World Health Organization (WHO).
In Macau, Aedes albopictus is the most common mosquito vector of dengue transmission.
The local health authority claims to have installed some 860 monitoring mechanisms since 2002, enabling the monthly collection of data to calculate the index.
The SS advises residents to remove stagnant water at home and working places in order to prevent mosquito eggs from breeding.
Residents are also being warned to be mindful of dengue symptoms especially when travelling to Southeast Asia.
