Hematology auto-analyzer (Sysmex KX-21N by Sysmex Corporation Kobe, Japan) was used in sample analysis. ANOVA and Kruskal Wallis were used for mean comparison.

Total white cell count, absolute lymphocyte, neutrophil, monocyte and eosinophil counts were significantly elevated in patients with leprosy compared to controls. The hemoglobin and mean corpuscular volume of patients with leprosy on treatment were significantly higher compared to those who had completed treatment, while the mean corpuscular hemoglobin concentration was significantly reduced. Overall, 65% of patients with leprosy were anemic. Eosinophil count showed good biomarker potential for leprosy reaction onset with AUC 0.709.

In late 2015, the temporal clustering of a Zika outbreak and microcephaly in newborn babies from northeastern Brazil, and the identification of a causal link between the two, led to the characterization of the congenital Zika syndrome. In the wake of the epidemic, several countries from Latin America advised women to postpone pregnancies for periods ranging from six months to two years. These recommendations initiated critical conversations about the challenges of implementing them in societies with limited access to contraception, widespread socioeconomic inequalities, and high rates of unplanned and adolescent pregnancies. The messaging targeted exclusively women, despite a high prevalence of imbalances in the relationship power, and addressed <i>all</i> women as a group, failing to recognize that the decision to postpone pregnancies will impact different women in different ways, depending on their age at the time. Finally, in several countries affected by the Zika epidemic, due to restrictive reproductive policies, legally terminating a pregnancy is no longer an option even at the earliest time when brain malformations as part of the congenital Zika syndrome can be detected by ultrasonography. The virus continued to circulate after 2016 in several countries.
