    continued COVID-19 pandemic has led to dramatic changes in human mobility, which have the potential to change the dynamics of the spread of other infectious diseases. Now, researchers reporting in the journal PLOS Neglected Tropical Diseases have found that social distance has led to a significant increase in dengue infections in Thailand, while dengue fever in Singapore or Malaysia has not changed.Dengue virus is transmitted by the Aedes aegypti mosquito and can cause severe fever, headache, muscle and joint pain, fatigue, nausea and vomiting. An estimated 105 million dengue infections occur each year, with the majority of cases concentrated in South-East Asia and the Western Pacific. In the area, COVID-19 has led to workplace closures, a ban on mass gatherings and, in some cases, a complete closure. This provides a natural experiment to assess the impact of reduced mobility and workplace exposure on dengue transmission.

    new work, Jue Tao Lim of the National University of Singapore and colleagues used national surveillance data up to mid-2020 to analyze the number of dengue cases in Thailand, Singapore and Malaysia. Information was also obtained on climate, COVID-19 interventions and overall census data.In Thailand, researchers found that social evacuations are expected to result in an increase of 4.32 cases per 100,000 people per month. The increase was mainly due to an increase in residential exposure compared to the workplace, resulting in an additional 2008 cases of dengue fever nationwide. However, no significant impact on dengue transmission has been detected in Singapore or Malaysia.“ National differences in the impact of social isolation policies on reported cases of dengue fever are thought to be due to differences in the structure of living in the workplace, and the increased risk of transmission of insect-borne viruses due to social isolation is largely due to increased exposure to the media in residences, the researchers said. "This suggests a need to understand the impact of geographical location on the risk of dengue transmission under new mixed population conditions, such as under social alienation policies."
