Table 2 Summary of recent similar published studies done in Sri Lanka

From: A study of the correlation between dengue and weather in Kandy City, Sri Lanka (2003 -2012) and lessons learned

Place Year published Study period Dengue notified/seropositive Weather variables studied Correlation identified
Colombo, Ratnapura, and Anuradhapura districts [21] 2013 2005–2011 Notified dengue cases Tmax, rainfall Tmax. and rainfall did not affect dengue incidence (but there was a mild correlation between dengue and rainfall in two cities).
Gampaha (it was one of the six Asian urban areas studied) [24] 2012 2006–2009 Seropositive dengue Rainfall A positive correlation was observed between the number of dengue cases and rainfall.
Western province of Sri Lanka (Colombo, Kalutara, and Gampaha districts combined) [25] 2009 2000–2004 Notified dengue cases Rainfall Dengue incidence was relatively low during heavy rainfall and increased when rainfall started to decrease, showing a 3–4-week lag. Dengue was strongly correlated with rain in most of the studied towns.
(No significant variations of temperature and humidity in were found, so they were not considered.)
