Globally,there have been multiple public health emergencies in recent decades.High rates of morbidity,occa-sionally mortality,and economic instability are usually associated with pandemics.One of the epidemics that has significantly increased morbidity and mortality worldwide is the human immunodeficiency virus(HIV)and acquired immune deficiency syndrome(AIDS)pandemic.HIV has a disproportionately negative impact on key populations.Strong leadership,effective communication,and sound science are necessary for public health emer-gency(PHE)responses to be successful.These three PHE response pillars are also essential for bridging the HIV response gap among key populations in the setting of restrictive laws.In this review,we explored the importance of these three pillars of successful PHEs responses,and how they are essential to closing the gap in the HIV response among key populations.Leaders must make decisions and instil a sense of authority in the populace during PHEs to foster trust and confidence.Leaders should base their choices on scientific evidence.Effective communication during PHEs should be proactive,polite,imaginative,innovative,and constructive.To address gaps in the HIV response among key populations,leaders must create a supportive environment for effective communication and scientific research,communication should be used to raise awareness of HIV and to dispel stigma and discrimination,while science should provide evidence of efficacy and effectiveness of interventions among key populations.

Background and objective:To provide good health and well-being as established by the Sustainable Development Goal(SDG)3,access to digital technologies can act as conduits to achieve such progress in a population.As guided by the World Health Organization,antenatal care(ANC)attendance is one of the measures promoted to curtail the global health burden of maternal and infant mortality.ANC services are seldom utilized to their full potential in Zimbabwe.This study explores if any of the women's digital technology characteristics were associated with antenatal care visits.Methods:The study analyzed population-based cross-sectional data with a subsample of 1 932 women aged 15-49 years from the 2019 Zimbabwe Multiple Indicator Cluster Survey.Test of associations with chi-square test,bivariate,and multivariate multinomial logistic regression analyses were used to examine the predictors of adequate(4-7)and optimal(≥ 8)ANC visits relative to undesirable(1-3)antenatal care visits among women who had given births 2 years before the survey.Results:The results indicate that 64.5％(1246/1 932)of the women attained adequate ANC while about 9.8％(189/1 932)attained optimal ANC.Reading a newspaper/magazine at least once a week(odds ratio[OR]1.73,β'=0.551,t=2.030,P=0.043)and watching television at least once a week(OR 1.72,β'=0.545,t=2.454,P=0.015),listening to the radio less than once a week(OR 1.28,β'=0.247,t=1.750,P=0.080),and owning a mobile phone(OR 1.48,β'=0.394,t=3.020,P=0.003)were positively associated with adequate ANC.Optimal ANC was significantly associated with women being able to read a newspaper at least once a week(OR 2.93,β'=1.074,t=3.120,P=0.002),listen to the radio less than once a week(OR 2.07,β'=0.73,t=2.700,P=0.007)and have ownership of a mobile phone(OR 1.88,β'=0.631,t=2.620,P=0.009).Conclusion:Access to a newspaper,radio,television,and mobile phone were important predictors of a woman's ability to achieve her ANC attendance.Policies to improve the knowledge of ANC packages can be facilitated using digital technology to achieve adequate and preferably optimal ANC in Zimbabwe.It is important to improve digital infrastructure to support digital technologies in providing ANC services.
