In 2014, over 40,000 people in Guangdong were reported to have dengue virus infection. The map shows the distribution of newly confirmed dengue cases in Guangdong between 22 September and 2 November, 2014.

In these six weeks, there were about 37,000 confirmed dengue cases, most of whom resided in Guangzhou. As shown by the standard deviational ellipses in the map, the dengue outbreak began in Guangzhou and Foshan. In the following 5 weeks, the ellipses have centred on the same area and expanded in size. While the number of incident dengue cases in Guangzhou peaked between 29 September and 12 October, increasing size of the ellipse suggested an expansion of the areas affected by dengue. As compared with other cities in Guangdong, a lower proportion of cases in Guangzhou in the ensuing three weeks might have contributed to the further expansion of the ellipse.

Data for the map were obtained from the website of Health Department of Guangdong Province.

2014年，廣東省有超過四萬人證實患上登革熱。地圖顯示於9月22日至11月2日期間，廣東省新增的登革熱確診個案分佈。

於該六個星期內，廣東省共出現約三萬七千宗登革熱確診個案，當中絕大部分都是廣州市居民。依圖中橢圓圈所示，是次登革熱爆發原於廣州、佛山一帶。接著的五週，橢圓圈的中心仍處於同一地帶，但形狀卻變得愈來愈大。廣州市的新增登革熱病例的高峰期是9月29日至10月12日，期間愈來愈大的橢圓圈代表受登革熱影響的地方有擴散跡象。其後的三個星期，愈來愈大的橢圓圈應與廣州市佔全省登革熱病例的比例下降相關。
