1996年，台湾食源性疾病的爆发急剧增加，此后发病率一直居高不下。疫情的增加与副溶血性弧菌的分离率高有关，1996年至1999年期间，副溶血性弧菌占总疫情的61%至71%。通过血清分型，从3743株V：副溶血菌分离株中鉴定出40种血清型，其中检出最多的是O3:K6。台湾早在1995年10月就可能出现O3:K6血清型，当时仅占副溶血性弧菌感染的0.6%。这一水平在1996年突然上升到50.1%，并在1997年达到峰值（83.8%）。对各病因组暴发概况的比较表明，1996年至1999年期间食源性疾病暴发的高发可归因于极高的O3:K6感染。1999年，O3:K6血清型仍然流行，占所有副溶血性弧菌感染的61.3%。由于其极高的感染频率及其在全球传播的能力，需要在国际上对这种生物进行密切监测。
The occurrence of food-borne disease outbreaks in Taiwan increased dramatically in 1996, and the incidence has since remained elevated. This increase in outbreaks is correlated with a high rate of isolation of Vibrio parahaemolyticus, which caused between 61 and 71% of the total outbreaks for the period 1996 to 1999. By serotyping, 40 serovars were identified from 3743 V: parahaemolyticus isolates, of which O3:K6 was the most frequently detected. The O3:K6 serovar could have emerged in Taiwan as early as October 1995 and at that time accounted for only 0.6% of the V. parahaemolyticus infections. This level increased suddenly to 50.1% in 1996 end reached a peak (83.8%) in 1997. Comparison of the outbreak profiles for the etiology groups indicates that the high incidence of food-borne disease outbreaks during 1996 to 1999 can be attributed to the extraordinarily high O3:K6 infections. In 1999, the O3:K6 serovar was still prevalent, and accounted for 61.3% of all V. parahaemolyticus infections. Due to its extraordinarily high infection frequency and its capability to spread globally, this organism needs to be intensively monitored internationally.
