Do the Floods Have the
Impacts on Vector-Born Diseases in Taiwan? |
Tzong-Luen Wang, MD, PhD, Hang Chang, MD |
| Abstract ---To
investigate if the Typhoon Nari that occurred in September 6 2001 had any impacts
on communicative diseases in Taiwan, we surveyed the data from the Epidemiological
Bulletins published in Center for Disease Control (Taiwan) from January 2000 to
April 2002. The medians of confirmed cases for dengue fever, Japanese encephalitis
and rickettsia were 3, 0 and 14, respectively. The gradual surge of dengue fever
was noted since October 2001 and persisted for 7 months. Rickettsia infection
had the same tendency and persisted for even five months. Analysis of the run
charts revealed that there were no endemic episodes of Japanese encephalitis after
Nari. For dengue fever, there were two surges; that is, one being the period from
August 2000 to November 2000, the other being the period from October 2001 to
April 2002. According to the analysis of the curve, the latter surge was statistically
significant. There were also two surges over the observation period for rickettsia
infection. The first one was during May 2000 to January 2001, whereas the second
one during November 2001 to March 2002. However, neither of the surges met the
criteria of significance. In conclusion, the floods due to Nari actually brought
the endemic outbreaks of dengue fever. Vector control remains an important issue
for post-flood disease surveillance. (Ann. Disaster Med 2002;1:43-50) |
