Dengue, Chikungunya cases surge after rains

Seek medical advice if fever lasts over two days: Expert  

• Says public participation in mosquito control measures is crucial to prevent a further spread of these diseases  
• Chikungunya cases are also increasing after several years of relatively low transmission

People experiencing a fever for more than two days should seek immediate medical attention and undergo appropriate blood tests, as Sri Lanka is witnessing a rise in both dengue and chikungunya infections following recent monsoon rains, Consultant Dr. Maheshaka Wijayawardena said.   

Dr. Wijayawardena warned that dengue cases have already reached tens of thousands this year, with the Western Province, particularly Colombo and Gampaha, reporting the highest number of infections. Chikungunya cases are also increasing after several years of relatively low transmission.   

“Both dengue and chikungunya are spread by the Aedes mosquitoes and often begin with similar symptoms such as fever, headache, body aches, joint pain and skin rashes, making early diagnosis difficult,” he said.   

He cautioned that dengue can become life-threatening if it progresses to Dengue Haemorrhagic Fever, which may lead to bleeding, shock and death if not treated promptly.   

“Patients with Dengue Haemorrhagic Fever often become more ill when the fever starts settling. Symptoms such as lethargy, abdominal pain and cold hands or feet should never be ignored,” Dr. Wijayawardena said.   

He also advised against the early use of non-steroidal anti-inflammatory drugs (NSAIDs) in fever patients, as they may increase the risk of bleeding in dengue cases.   

Urging the public to focus on prevention, Dr. Wijayawardena called on communities to eliminate mosquito breeding sites, use mosquito repellents and remain vigilant as continued rains are expected to increase the risk of transmission.   

“Public participation in mosquito control measures is crucial if we are to prevent a further spread of these diseases,” he said.
