Introduction:

Anaplasmosis is an acute febrille illness transmitted through tick. In humans, the most important species is Anaplasma phagocytophilum.

Objective:

To meta-analyze the reported prevalence of anaplasma in humans, according to worldwide scientific literature.

Method:

Systematic revisión of literature according to Prisma phases with 14 strategies in search of three multidisciplinary databases. We guaranteed reproducibility and evaluation of the methodological quality. Analysis were based in proportions with confidence intervals of 95%.

Results:

15 research works published between 2004 and 2017 were systematized. Most of them occurred in Poland (20%) and China (20%). 73% used IFI and the rest used PCR. Most of study groups were related to subjects with occupational exposition or contact with the infected animals. The prevalence of PCR was de 15.6% (CI of 95% = 13.1 - 18.0), with IFI of 9.3% (CI of 95% = 8.5 - 10.0).

Conclusion:

Studies reported a high frequency of infection and exposition to Anaplasma spp. in humans, while they identified important aspects to orientate later studies related to cross infections, coinfections and the circulation of the vector.
