<p><strong>BACKGROUND:</strong> Outbreak of cerebrospinal meningitis (CSM) remains a major public health concern in Nigeria, particularly in northern Nigeria. The paper evaluates the effect of mass vaccination against cerebrospinal meningitis outbreak in 2013 on the incidence rate in 2014 and 2015, and to document lessons learnt from field experiences of the meningitis epidemic surveillance in Kebbi State, North-west, Nigeria.</p><p><strong>METHODS:</strong> The authors analysed cerebrospinal meningitis surveillance data generated from the routine integrated disease surveillance and response (IDSR) programme executed by the Ministry of Health with support from the World Health Organisation (WHO). Cerebrospinal fluid (CSF) samples via lumbar puncture procedures from a small proportion of all suspected cases that met the standard case definitions were collected, and then tested using the rapid agglutination test kits (Pastorex) at the state public health laboratory. The WHO supported the trained Local Government Areas Disease Surveillance and Notification Officers to ensure data quality.</p><p><strong>RESULTS: </strong>A total of 544 and 1,992 cases were analysed in 2014 and 2015 respectively. In 2014, 14% CSF samples were taken and 55.1% tested positive to <em>Neisseria meningitidis </em>type C. Of all the cases in 2014, 14% were reported dead. Further, in 2015, 4% CSF samples were tested and 83% were positive to <em>Neisseria meningitidis </em>type C. Of the total 1,992 cases in 2015, 4% were reported dead. Gender and CSF sample testing significantly predicts survival in 2014 (p&lt;0.05).</p><p><strong>CONCLUSION: </strong>Desired political will and comprehensive epidemic prevention and control strategies are needed for effective control of seasonal outbreaks of CSM and other epidemic-prone diseases. Need for infrastructural and capacity development of hospital and state public health laboratories for adequate surveillance, testing of samples collected and effective case management cannot be over-emphasized.</p>

Microcystins (MCs) are blue-green algal toxins produced by freshwater cyanobacteria. Their environmentally relevant concentrations throughout global surface waters have tampered with human populations’ drinking and recreational supplies. MCs have gained immense public health attention due to their potential health effects. Microcystin-LR (MC-LR) is the most toxic variant of the MCs. Investigations on MC-LR toxicity and detection in water signify a growing potential environmental health concern worldwide. The World Health Organization established a provisional drinking water guidance value of 1 μg/L and a provisional recreational exposure guidance value of 10 μg/L for MC-LR. This review surveys human MC exposure pathways and integrates epidemiological studies to support MCs’ critical exposure pathways. A discussion on monitoring and mitigation strategies provides a guide for policy development in adopting MCs’ regulatory levels to protect public health.

Abstract Recognizing that antimicrobial resistance (AMR) poses a serious threat to global public health, the World Health Organization (WHO) has adopted a Global Action Plan (GAP) at the May 2015 World Health Assembly. Underscoring that systematic misuse and overuse of drugs in human medicine and food production is a global public health concern, the GAP-AMR urges concerted efforts across governments and private sectors, including pharmaceutical industry, medical professionals, agricultural industry, among others. The GAP has a threefold aim: (1) to ensure a continuous use of effective and safe medicines for treatment and prevention of infectious diseases; (2) to encourage a responsible use of medicines; and (3) to engage countries to develop their national actions on AMR in keeping with the recommendations. While the GAP is a necessary step to enable multilateral actions, it must be supported by effective governance in order to realize the proposed aims. This chapter has a threefold purpose: (1) To identify regulatory principles embedded in key WHO documents relating to AMR and the GAP-AMR; (2) To consider the legal and regulatory actions or interventions that countries could use to strengthen their regulatory lever for AMR containment; and (3) To highlight the crucial role of the regulatory lever in enabling other levers under a whole-of-system approach. Effective AMR containment requires a clearer understanding of how the regulatory lever could be implemented or enabled within health systems, as well as how it underscores and interacts with other levers within a whole-of-system approach.

Tuberculosis (TB) is a major public health concern worldwide: despite a regular, although slow, decline in incidence over the last decade, as many as 8.6 million new cases and 1.3 million deaths were estimated to have occurred in 2012. TB is by all means a poverty-related disease, mainly affecting the most vulnerable populations in the poorest countries. The presence of multidrug-resistant strains of M. tuberculosis in most countries, with some where prevalence is high, is among the major challenges for TB control, which may hinder recent achievements especially in some settings. Early TB case detection especially in resource-constrained settings and in marginalized groups remains a challenge, and about 3 million people are estimated to remain undiagnosed or not notified and untreated. The World Health Organization (WHO) has recently launched the new global TB strategy for the “post-2015 era” aimed at “ending the global TB epidemic” by 2035, based on the three pillars that emphasize patient-centred TB care and prevention, bold policies and supportive systems, and intensified research and innovation.This paper aims to provide an overview of the global TB epidemiology as well as of the main challenges that must be faced to eliminate the disease as a public health problem everywhere.

Background. Community consumption of herbal plants in developing countries is a common practice, however, scarcity of information on their physiochemical composition is a major public health concern. In Uganda, Vernonia amygdalina is of interest in rural communities due to its therapeutical action on both bacterial and protozoal parasites, however no studies have been conducted to assess the heavy metal concentrations in traditional plants used in alternative medicine. The aim of the study was to establish concentrations of heavy metals in Vernonia amygdalina, model the estimated daily intake (EDI), and assess both the non-cancer-related health risk using the target hazard quotient (THQ), and the risk related to cancer through the incremental lifetime cancer risk (ILCR) for the Ugandan population. Methods. Leaves of Vernonia amygdalina were collected from 20 georeferenced villages and processed into powder in the laboratory using standard methods. These were then analyzed in the laboratory using an atomic absorption spectrometer for lead (Pb), chromium (Cr), copper (Cu), zinc (Zn), cobalt (Co), iron (Fe), cadmium (Cd), and nickel (Ni). Concentrations were compared against the World Health Organization (WHO) limits. The EDI, THQ, and ILCR were modelled and significance was measured at 95% confidence. Results. The study showed that mean ± SEM concentrations of heavy metals were highest in the order of Cr, 121.8 ± 4.291 ppm > Ni, 84.09 ± 2.725 ppm > Zn, 53.87 ± 2.277 ppm > Pb, 40.61 ± 3.891 ppm > Cu, 28.75 ± 2.202 ppm > Fe, 14.15 ± 0.7271 ppm > Co, 7.923 ± 0.7674 ppm > Cd, 0.1163 ± 0.005714 ppm. Concentrations of Pb, Cr, Zn, Co, and Ni were significantly higher than the WHO limits. The EDI was significantly higher in children than in adults, demonstrating an increased risk of toxicity in children. The THQ and ILCR were over 1000 times higher in all Ugandans, demonstrating the undesirable health risks following oral consumption of Vernonia amygdalina due to very high Cr and Ni toxicities, respectively. Conclusion. Consumption of raw Vernonia amygdalina was associated with a high carcinogenic risk, demonstrating a need to enact policies to promote physiochemical screening of herbal medicines used in developing countries against toxic compounds.

Abstract The current public health crisis has radically altered the social and civic involvement in Southeast Asia. Although the virus has shifted the landscape of engagement, it has not dampened the enthusiasm of the public. In 2020–2021, more people than ever seem to be paying attention and even getting involved in activism. Many dramatic events happened during the coronavirus crisis such as from protests in support of the Black Lives Matter movement, public activism around the environment, economic inequality, authoritarianism and human rights violations. In Indonesia, the Philippines, Malaysia, Thailand and just recently Myanmar. The journal has lately published about the ‘Relationship of George Floyd protests to increases in COVID-19 cases using event study methodology’ and it has rightly expressed that the Centers for Disease Control and Prevention (CDC)-recommended social distancing guidelines must be followed in a protest situation. In response to the situation of social activism in Southeast Asia, one must follow the CDC-recommended and World Health Organization (WHO) guidelines in the Region. Although protesting is an individual human right, one must also be cautious and be aware of the deadly virus since we are still in a pandemic and the COVID-19 virus continues to mutate.

Hepatitis C virus (HCV) infection is considered by the World Health Organization (WHO) to be a serious public health concern and one of the major public health priorities. In 2005, it was estimated that there are 185 million anti-HCV positive people in the world, which constitutes 2.8% of the global population. Our study estimates the anti-HCV seroprevalence in the working age population (15–64 years-old), mostly urban and suburban residents, in Poland from 2004 to 2014. The studied group consisted of 61,805 working-age population representatives whose data were obtained from electronic medical records of an outpatient clinic network operating on a countrywide level. Positive anti-HCV test results were obtained in 957 patients, representing 1.5% of the whole population studied throughout the analysed period. The average age of all anti-HCV positive patients was 36.8 years. Analysis of the data suggests that the proportion of anti-HCV positive patients decreased over the study period (mean positive anti-HCV = -0.0017 × year + 3.3715; R2 = 0.7558). In 2004, positive results were noted among 3.2% of patients undergoing HCV antibody tests, but in 2014, the percentage of patients with a positive result stood at 1.1%. The apparent decrease affected men and women similarly. Our study also provides evidence that screening people born before 1965 could be beneficial.

Antimicrobial resistance is a major public health concern worldwide affecting humans, animals and the environment. However, data is lacking especially in developing countries. Thus, the World Health Organization developed a One-Health surveillance project called Tricycle focusing on the prevalence of ESBL-producing Escherichia coli in humans, animals, and the environment. Here we present the first results of the human community component of Tricycle in Madagascar. From July 2018 to April 2019, rectal swabs from 492 pregnant women from Antananarivo, Mahajanga, Ambatondrazaka, and Toamasina were tested for ESBL-E. coli carriage. Demographic, sociological and environmental risk factors were investigated, and E. coli isolates were characterized (antibiotic susceptibility, resistance and virulence genes, plasmids, and genomic diversity). ESBL-E. coli prevalence carriage in pregnant women was 34% varying from 12% (Toamasina) to 65% (Ambatondrazaka). The main risk factor associated with ESBL-E. coli carriage was the rainy season (OR = 2.9, 95% CI 1.3–5.6, p = 0.009). Whole genome sequencing was performed on 168 isolates from 144 participants. blaCTX–M–15 was the most frequent ESBL gene (86%). One isolate was resistant to carbapenems and carried the blaNDM–5 gene. Most isolates belonged to commensalism associated phylogenetic groups A, B1, and C (90%) and marginally to extra-intestinal virulence associated phylogenetic groups B2, D and F (10%). Multi locus sequence typing showed 67 different sequence types gathered in 17 clonal complexes (STc), the most frequent being STc10/phylogroup A (35%), followed distantly by the emerging STc155/phylogroup B1 (7%), STc38/phylogroup D (4%) and STc131/phylogroup B2 (3%). While a wide diversity of clones has been observed, SNP analysis revealed several genetically close isolates (n = 34/168) which suggests human-to-human transmissions. IncY plasmids were found with an unusual prevalence (23%), all carrying a blaCTX–M–15. Most of them (85%) showed substantial homology (≥85%) suggesting a dissemination of IncY ESBL plasmids in Madagascar. This large-scale study reveals a high prevalence of ESBL-E. coli among pregnant women in four cities in Madagascar associated with warmth and rainfall. It shows the great diversity of E. coli disseminating throughout the country but also transmission of specific clones and spread of plasmids. This highlights the urgent need of public-health interventions to control antibiotic resistance in the country.

Abstract Bovine mastitis, commonly caused by bacteria, is one of the most devastating diseases for the dairy industry worldwide, with high economic, social, and public health impacts. Among the pathogenic bacteria, Staphylococcus aureus is one of the leading pathogens in most countries. Success rate of antibiotic treatment is low such that effective control of S. aureus induced mastitis is currently only possible through prevention of new infections and culling of infected animals. The infection is usually subclinical, causing elevated somatic cell counts but no detectable changes in milk or the udder. S. aureus persists in mammary glands, teat canals, and teat lesions of infected cows and is transmitted to other cows during milking. The direct evidence of cross-species transmission of S. aureus is still scarce. Nevertheless, accumulating indirect evidence supports the zoonotic potential for S. aureus from bovine mastitis to humans. In addition to direct contact, aerosol exposures may also be an important mechanism for the transmission. While animal-adapted livestock-associated methicillin-resistant S. aureus has been known for many years, most S. aureus isolated from mastitic milk in Canada are methicillin-sensitive. S. aureus induced mastitis is a common reason for therapeutic and/or prophylactic use of antibiotics on dairy farms. Occurrence of multidrug resistant, especially methicillin-resistant, S. aureus has been a major public health concern. In this talk, we will address the pathogenesis and strain spectrum of S. aureus induced bovine mastitis, review existing evidence for inter-species transmission, and discuss possible transmission of methicillin-resistance determinants. This talk aims to emphasize the need for the one-health approach for prevention and treatment of S. aureus induced mastitis, in order to provide safe and nutritious milk and milk products to consumers.

AbstractZika virus continues to pose a significant global health threat. While the outbreak pattern may seemingly mirror those of other arboviruses, unique transmission characteristics and clinical outcomes warrant a different approach to traditional public health practices. Sexual transmission and virus-associated fetal and nonfetal neurologic disorders specifically challenge conventional methods of disease protection and prevention with regard to vector control, disease surveillance, and health risk communication. The protocols for outbreak and case limitation led by the World Health Organization (in accordance with Public Health Emergency of International Concern declaration) may be augmented by localized risk categorization and assignment for Zika and future emergent outbreaks. There is currently a great deal of “behind the scenes” discussion about modifications to the formal process described in the International Health Regulations. A scalable, adaptable, and flexible process is needed that can be customized to a specific threat. (Disaster Med Public Health Preparedness. 2017;11:279–284)

Statistical Process

Statistical challenges in monitoring modern biosurveillance data are well described in the literature. Even though assumptions of normality, independence, and stationarity are typically violated in the biosurveillance data, statistical process control (SPC) charts adopted from industry have been widely used in public health for communicable disease monitoring. But, blind usage of SPC charts in public health that ignores the characteristics of disease surveillance data may result in poor detection of disease outbreaks and/or excessive false-positive alarms. Thus, improved biosurveillance systems are clearly needed, and participation of statisticians knowledgeable in SPC alongside epidemiologists in the design and evaluation of such systems can be more productive. We describe and study a method for monitoring reportable disease counts using a Poisson distribution whose mean is allowed to vary depending on the week of the year. The seasonality is modeled by a trigonometric function whose parameters can be estimated by some baseline set of data. We study the ability of such a model to detect an outbreak. Specifically, we estimate the probability of detection (POD), the average number of weeks to signal given that a signal has occurred (conditional expected delay, or CED), and the false-positive rate (FPR, the average number of false-alarms per year).
