“…This appears to be the first study conducted in Liberia assessing the prevalence of P. falciparum infection among pregnant women after the Ebola epidemic that led to the interruption of malaria control [ 10 , 13 ]. This study found a 12.3% prevalence of P. falciparum (by qPCR) among pregnant women attending to their first ANC visit at a non-government hospital in Monrovia, and before administration of any IPTp-SP dose.…”

“…Both the scale-up of ITN distribution and IPTp-SP, as strategies to protect pregnant women from malaria, were discontinued during the recent Ebola epidemic that resulted in over 10,000 deaths in Liberia, Sierra Leone and Guinea Conakry [ 10 – 12 ]. Mathematical modelling estimated that the interruption of malaria control could have caused a 62% increase in mortality by malaria [ 13 ].…”

BackgroundDisruption of malaria control strategies during the West African 2014–2016 Ebola epidemic led to an increase in malaria-attributable mortality. However, recent data on malaria infection in vulnerable groups, such as pregnant women, are lacking in this post-Ebola scenario. This cross-sectional study aimed to assess the prevalence of Plasmodium falciparum infection and of molecular markers of drug resistance among pregnant women attending antenatal care in Monrovia, capital of Liberia.MethodsFrom October 2016 to June 2017, all pregnant women attending their first antenatal care visit at the Saint Joseph’s Catholic Hospital, Monrovia, were invited to participate in the study. In addition to their routine antenatal care tests, capillary blood spotted onto filter papers were collected from all consenting participants to determine presence of P. falciparum by real-time quantitative PCR. Molecular markers of anti-malarial drug resistance were assessed through Sanger sequencing and quantitative PCR in specimens positive for P. falciparum analysis.ResultsOf the 195 women participants, 24 (12.3%) were P. falciparum-positive by qPCR. Infected women tended to be more commonly primigravidae and younger than uninfected ones. Parasite densities were higher in primigravidae. Fever was more frequently detected among the infected women. No statistically significant association between P. falciparum infection and haemoglobin levels or insecticide-treated net use was found. While high prevalence of genetic polymorphisms associated with chloroquine and amodiaquine resistance were detected, no molecular markers of artemisinin resistance were observed.ConclusionPlasmodium falciparum infections are expected to occur in at least one in every eight women attending first ANC at private clinics in Monrovia and outside the peak of the rainy season. Young primigravidae are at increased risk of P. falciparum infection. Molecular analyses did not provide evidence of resistance to artemisinins among the P. falciparum isolates tested. Further epidemiological studies involving pregnant women are necessary to describe the risk of malaria in this highly susceptible group outside Monrovia, as well as to closely monitor the emergence of resistance to anti-malarials, as recommended by the Liberian National Malaria Control Programme.

“…Analyses using routine health information system (RHIS) data originating from Guinea and Sierra Leone have recently chronicled the effect of the EVD epidemic on the delivery of public-sector care for maternal, child, and reproductive health services, showing dramatic decreases during the Ebola outbreak (on the order of 50% declines) and sustained low levels not suggesting recovery [ 3 – 5 ]. Previous descriptive studies using RHIS data from Liberia have shown decreases in maternal and child health (MCH) indicators [ 6 , 7 ], malaria treatment [ 8 ], HIV testing [ 9 ], and tuberculosis diagnoses [ 10 ] during the EVD outbreak. Others have estimated that EVD-related disruptions in treating malaria alone will contribute to significantly more excess deaths than direct EVD-related mortality [ 11 ].…”

BackgroundThe aim of this study is to estimate the immediate and lasting effects of the 2014–2015 Ebola virus disease (EVD) outbreak on public-sector primary healthcare delivery in Liberia using 7 years of comprehensive routine health information system data.Methods and findingsWe analyzed 10 key primary healthcare indicators before, during, and after the EVD outbreak using 31,836 facility-month service outputs from 1 January 2010 to 31 December 2016 across a census of 379 public-sector health facilities in Liberia (excluding Montserrado County). All indicators had statistically significant decreases during the first 4 months of the EVD outbreak, with all indicators having their lowest raw mean outputs in August 2014. Decreases in outputs comparing the end of the initial EVD period (September 2014) to May 2014 (pre-EVD) ranged in magnitude from a 67.3% decrease in measles vaccinations (95% CI: −77.9%, −56.8%, p < 0.001) and a 61.4% decrease in artemisinin-based combination therapy (ACT) treatments for malaria (95% CI: −69.0%, −53.8%, p < 0.001) to a 35.2% decrease in first antenatal care (ANC) visits (95% CI: −45.8%, −24.7%, p < 0.001) and a 38.5% decrease in medroxyprogesterone acetate doses (95% CI: −47.6%, −29.5%, p < 0.001). Following the nadir of system outputs in August 2014, all indicators showed statistically significant increases from October 2014 to December 2014. All indicators had significant positive trends during the post-EVD period, with every system output exceeding pre-Ebola forecasted trends for 3 consecutive months by November 2016. Health system outputs lost during and after the EVD outbreak were large and sustained for most indicators. Prior to exceeding pre-EVD forecasted trends for 3 months, we estimate statistically significant cumulative losses of −776,110 clinic visits (95% CI: −1,480,896, −101,357, p = 0.030); −24,449 bacille Calmette–Guérin vaccinations (95% CI: −45,947, −2,020, p = 0.032); −9,129 measles vaccinations (95% CI: −12,312, −5,659, p < 0.001); −17,191 postnatal care (PNC) visits within 6 weeks of birth (95% CI: −28,344, −5,775, p = 0.002); and −101,857 ACT malaria treatments (95% CI: −205,839, −2,139, p = 0.044) due to the EVD outbreak. Other outputs showed statistically significant cumulative losses only through December 2014, including losses of −12,941 first pentavalent vaccinations (95% CI: −20,309, −5,527, p = 0.002); −5,122 institutional births (95% CI: −8,767, −1,234, p = 0.003); and −45,024 acute respiratory infections treated (95% CI: −66,185, −24,019, p < 0.001). Compared to pre-EVD forecasted trends, medroxyprogesterone acetate doses and first ANC visits did not show statistically significant net losses. ACT treatment for malaria was the only indicator with an estimated net increase in system outputs through December 2016, showing an excess of +78,583 outputs (95% CI: −309,417, +450,661, p = 0.634) compared to pre-EVD forecasted trends, although this increase was not statistically significant. However, comparing December 2013 to December 2017, ACT malaria cases h...

The West African Ebola virus disease (EVD) outbreak was the largest in history. The vast majority of cases were reported in Guinea, Sierra Leone and Liberia. Altogether, 28 646 people were infected and 11 323 died. 1 One of the explanations for the extent of the outbreak was the lack of response of local health systems. These health systems were incapable of responding adequately to the outbreak due to a lack of human resources, information, research, supply of medical products, financing and governance. 2 The devastating effect of the Ebola outbreak stretched far beyond the number of Ebola cases, and resulted in the deterioration of the provision and utilisation of routine health care. On the one hand the EVD outbreak compromised the functioning of the health system, due to the deaths of many health care workers and the closure of health facilities, 3,4 while at the same time communities had little trust in the capacity of providers to secure safe health care. In Ebola-affected communities many individuals feared to seek care, even for curable conditions. 4,5 The manner in which the provision and utilisation of programmes were affected by the outbreak was difficult to monitor during the outbreak response, given the state of emergency. All the attention of national and international health care providers was focused on limiting further spread of EVD, and reducing mortality in infected patients. We therefore studied in retrospect the effect of the Ebola outbreak on health system performance. Two Structured Operational Research Training Initiative (SORT IT) courses were organised, one in Liberia and one in Sierra Leone. The participants, the first authors of the manuscripts included in this supplement, were involved in the local health programmes during the Ebola outbreak. Course participation was defined as successful if the participant submitted a scientific manuscript to a peer-reviewed journal by the end of the course. 6 Sixteen studies were conducted, and are assembled here for this special issue. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Through the study of routine data the performance of a wide range of programmes was assessed before, during and after the outbreak. These studies present data from mother and child health care services, the human immunodeficiency virus (HIV), tuberculosis, vaccination, malaria, malnutrition and non-communicable diseases programmes. In addition, infection prevention monitoring, community health worker programme and performance-based financing are included.The different studies illustrate how service delivery and utilisation of most programmes dropped significantly during the Ebola outbreak. The greater the area affected, the sharper the decline, and the longer it took for performance to recover to pre-Ebola levels. The level of programme performance pre-Ebola also affected recovery post-Ebola. For example, in Liberia the already struggling immunisation programme was further weakened during the outbreak and took significant time to recover post-Ebola. 19 Ne...
