Philippines dengue tally tops 170K!!! Philippines health officials reported an additional 12,000 + dengue fever cases since our last report (https://bit.ly/3D0kpyD) bringing the cumulative total to 172,985 through September 24. This is a 197 percent increase compared to the same period last year (58,157). The death toll has risen to 528 year to date. Central Luzon reports the most cases, accounting for 20%, with 34,399. This is followed by the National Capital Region (NCR) with 18,544, Calabarzon (14,943) and the Cagayan valley region (14,293). Dengue is mainly spread by Aedes aegypti mosquitoes and, to a lesser extent, Aedes albopictus mosquitoes. It is caused by any of four dengue virus serotypes, each of which can cause dengue fever or severe dengue. The prevalence of individual serotypes varies across different geographies, countries, regions, seasons and over time. Recovery from infection by one serotype provides lifelong immunity against only that serotype, and later exposure to any of the remaining serotypes is associated with an increased risk of severe disease.
