In early 2016, it was suspected that there were more deaths in Pernambuco than in previous years during an epidemic of chikungunya. This study tested whether there was an increased number of deaths and, if so, whether this increase could be related to a chikungunya epidemic. Indeed, there was an increase of 4235 deaths in 2016 compared to the average of the four previous years, and the highest differences were found during the peak period of the epidemic. It was evident that not all of these deaths could be attributed to complications of chikungunya. However, considering the temporal overlap, some of these deaths may have been caused by the aggravation of pre-existing comorbidities or complications caused directly by chikungunya virus infection.
2016年初，有人怀疑在伯南布哥州基孔肯雅热疫情期间死亡人数比前几年更多。本研究检验了死亡人数是否增加，以及如果增加，这种增加是否可能与基孔肯雅热疫情有关。的确，与此前四年的平均水平相比，2016年死亡人数增加了4235人，且在疫情高峰期差异最为明显。很明显，并非所有这些死亡都可归因于基孔肯雅热的并发症。然而，考虑到时间上的重叠，其中一些死亡可能是由先前存在的合并症加重或基孔肯雅病毒感染直接引起的并发症所致。
