Abstract

Dengue infection continues to be a major public health issue and has been  a challenge to health authorities for years due to several reasons. It is well known that the virus, mosquito and human factors play significant roles in the transmission of the infection. Traditionally, several preventive measures that are targeted towards the mosquito are well implemented in several countries, including Sri Lanka. Studies have shown that human mobility is a contributing factor in dengue infection and the objective of this report is to give an account on the possibility of human mobility as a major contributing factor for the outbreak of dengue infection in northern Sri Lanka.

The gateway “A9” was reopened to the public in mid-2009, as the political unrest had come to a halt by May 2009. Northern Sri Lanka was thereby reconnected with the south, which increased population mobility both ways. An increase in the incidence rate of dengue fever from 10.72 in 2008 to 539.65 in 2010, supported the hypothesis of the possible contribution of human mobility in the  dengue outbreak of 2010. Human mobility factors are often overlooked when considering preventive aspects. Preventive measures targeting human movements may enhance effectiveness of dengue control programs.
