Storm-related carbon monoxide (CO) poisoning outbreaks occurred in Connecticut in 2011 and 2012, despite efforts to improve public messaging. We describe the cases and incidents and identify possible preventive interventions. We defined cases as blood carboxyhemoglobin ≥9.0% among persons exposed to alternative power or heat sources because of storm-related losses. We identified 133 cases, including 3 deaths, in 2011 and 30 in 2012, associated with 72 and 11 incidents, respectively. Racial/ethnic minorities were overrepresented (60% of 2011 patients; 48% in 2012), compared with Connecticut's minority population (29%). Generator or charcoal misuse (83% in 2011; 100% in 2012) caused the majority of incidents. Few CO-source operators recalled media or product CO warnings. Incorrect generator and charcoal use, racial/ethnic disparities, and incomplete penetration of warning messages characterized both outbreaks. A multifaceted approach is needed to decrease postdisaster CO poisonings.
尽管已努力改进公共信息传播，但2011年和2012年康涅狄格州仍发生了与风暴相关的一氧化碳（CO）中毒事件。我们描述了这些病例和事件，并确定了可能的预防干预措施。我们将病例定义为因风暴相关损失而接触替代电源或热源的人群中血液碳氧血红蛋白≥9.0%。我们在2011年确定了133例病例，包括3例死亡，在2012年确定了30例病例，分别与72起和11起事件相关。与康涅狄格州的少数族裔人口（29%）相比，少数族裔在病例中所占比例过高（2011年患者中的60%；2012年的48%）。发电机或木炭使用不当（2011年为83%；2012年为100%）导致了大多数事件。很少有CO源操作人员记得媒体或产品的CO警告。不正确的发电机和木炭使用、种族/族裔差异以及警告信息的不完全传播是这两次事件的特点。需要采取多方面的方法来减少灾后CO中毒事件。
