Assessment of Suspected COVID-19 Deaths in Nonhealthcare Settings in Côte d'Ivoire, March 11 to July 31, 2020.

According to hospital records, 5 months after reporting its first case of COVID-19, Côte d'Ivoire reported only 102 deaths. We conducted a community mortality survey in the 13 districts where 95% of COVID-19 cases were reported to assess COVID-19 mortality in nonhealthcare settings. To identify suspected COVID-19 deaths in communities, we used data from social and administrative institutions, such as police and fire departments, funeral homes, and places of worship, whose functions include providing services related to deaths. Our survey identified 54 (17.6%) suspected COVID-19 deaths, which is more than half of the official reported number. Our study showed that in areas with low access to healthcare and poorly functioning death notification and registration systems, community-based data sources could be used to identify suspected COVID-19 deaths outside of the health sector. They can provide early warning data on events, such as an unusual number of community deaths or diseases.

Community-Based Surveillance in Côte d'Ivoire.

Community-based surveillance can be an important component of early warning systems. In 2016, the Côte d'Ivoire Ministry of Health launched a community-based surveillance project in 3 districts along the Guinea border. Community health workers were trained in detection and immediate reporting of diseases and events using a text-messaging platform. In December 2017, surveillance data from before and after implementation of community-based surveillance were analyzed in intervention and control districts. A total of 3,734 signals of priority diseases and 4,918 unusual health events were reported, of which 420 were investigated as suspect diseases and none were investigated as unusual health events. Of the 420 suspected cases reported, 23 (6%) were laboratory confirmed for a specific pathogen. Following implementation of community-based surveillance, 5-fold and 8-fold increases in reporting of suspected measles and yellow fever clusters, respectively, were documented. Reporting incidence rates in intervention districts for suspected measles, yellow fever, and acute flaccid paralysis were significantly higher after implementation, with a difference of 29.2, 19.0, and 2.5 cases per 100,000 person-years, respectively. All rate differences were significantly higher in intervention districts (p < 0.05); no significant increase in reporting was noted in control districts. These findings suggest that community-based surveillance strengthened detection and reporting capacity for several suspect priority diseases and events. However, the surveillance program was very sensitive, resulting in numerous false-positives. Learning from the community-based surveillance implementation experience, the ministry of health is revising signal definitions to reduce sensitivity and increase specificity, reviewing training materials, considering scaling up sustainable reporting platforms, and standardizing community health worker roles.

Global Health Security Agenda Implementation: A Case for Community Engagement.

In today's interconnected world, infectious diseases can spread rapidly within and between countries. The 2014-2016 Ebola epidemic in Guinea, Liberia, and Sierra Leone underscored the inability of countries with limited capacities and weak public health systems to respond effectively to outbreaks. To mitigate future health threats, nations and international organizations launched the Global Health Security Agenda (GHSA) to accelerate compliance with the WHO's International Health Regulations, so as to enhance global protection from infectious disease threats. To advance GHSA's mandate to build capacity to prevent, detect, and respond to infectious diseases, and thereby contain threats at their source, community engagement is needed. This article advocates for community engagement in GHSA implementation, using examples from 3 GHSA action packages. A country's ability to prevent a local disease outbreak from becoming an epidemic often rests with the level of knowledge about the situation and the actions taken at the community level.

Polio outbreak among nomads in Chad: outbreak response and lessons learned.

BACKGROUND: In response to the 2011 and 2012 polio epidemic in Chad, Chad's Ministry of Public Health, with support from Global Polio Eradication Initiative partners, took steps to increase vaccination coverage of nomadic children with targeted polio campaigns. This article describes the strategies we used to vaccinate nomads in 3 districts of Chad. METHODS: Our targeted interventions involved using mobile vaccination teams, recruiting local nomads to identify settlements, using social mobilization, and offering vaccinations to children, women, and animals. RESULTS: Vaccination coverage of nomadic children 0-59 months of age increased, particularly among those never before vaccinated against polio. These increases occurred mostly in the intervention districts of Dourbali, from 2956 to 8164 vaccinated children, and Kyabe, from 7319 to 15 868. The number of first-time vaccinated nomadic children also increased the most in these districts, from 60 to 131 in Dourbali and from 1302 to 2973 in Kyabe. Coverage in the Massaguet district was only 37.7%. CONCLUSIONS: Our success was probably due to (1) appointment of staff to oversee implementation, (2) engagement of the national government and its partners, (3) participation of nomadic community leaders, (4) intersectoral collaboration between human and animal health services, and (5) flexibility and capacity of vaccinators to vaccinate when and where nomads were available.

Influenza vaccine for high-risk non-elderly adults: a national survey of subspecialists.

Despite long-standing recommendations for non-elderly adults with certain chronic pulmonary, cardiovascular and metabolic conditions to receive influenza vaccine, vaccination rates remain low. Visits to subspecialists represent an important vaccination opportunity, but little is known regarding subspecialists' perceptions related to influenza vaccination. In February 2003, we conducted a cross-sectional mail survey of a random sample (N = 2,007) of board-certified cardiologists, endocrinologists and pulmonologists from the entire United States who provided outpatient care to adults aged 18-64 years, to assess their patterns of and attitudes toward administering influenza vaccine to high-risk, non-elderly patients. The overall response rate was 33%. Among 621 eligible respondents, 483 stocked influenza vaccine in their practice (Stockers) and 138 did not stock the vaccine (Non-Stockers). Pulmonologists were most likely to stock vaccine and strongly recommend vaccination; cardiologists were least likely. Among Stockers, barriers to vaccination varied by subspecialty. Among Non-Stockers, the most common factor in the decision to not stock vaccine was the perception that patients will receive the vaccine elsewhere. Most subspecialists who provide care to a large proportion of high-risk, non-elderly persons recommend influenza vaccination to some degree, particularly pulmonologists. To reduce missed opportunities overall, subspecialists should be encouraged to vaccinate patients who say that they plan to get the vaccine elsewhere. For cardiologists in particular, barriers to stocking influenza vaccine and recommending vaccination more strongly must be addressed.

Improving influenza, pneumococcal polysaccharide, and hepatitis B vaccination coverage among adults aged <65 years at high risk: a report on recommendations of the Task Force on Community Preventive Services.

The Task Force on Community Preventive Services conducted systematic reviews to evaluate the effectiveness of interventions to improve targeted vaccination coverage (i.e., coverage with vaccines recommended for some but not all persons in an age range on the basis of risk for exposure or disease) among adults aged <65 years at high risk when implemented alone (single-component interventions) and in combination with other interventions (multicomponent interventions). A 1999 report by the Task Force examined the effectiveness of interventions to increase coverage with universally recommended vaccinations (i.e., vaccines recommended for all persons in particular age groups). Three targeted vaccinations recommended for populations at risk are addressed in this review: influenza, pneumococcal polysaccharide, and hepatitis B. The Task Force identified evidence that certain combinations of interventions have improved vaccination coverage. To increase targeted vaccination coverage, the Task Force recommends a combination of interventions that include selected interventions from two or three categories of interventions (i.e., increasing community demand for vaccinations, enhancing access to vaccination services, and provider- or system-based interventions). The Task Force also recommends provider reminders, when implemented alone, to improve targeted vaccination coverage. This report provides additional information about population-based interventions to improve the coverage of influenza, pneumococcal polysaccharide, and hepatitis B vaccines among populations at risk, briefly describes how the reviews were conducted, and provides information that can help in applying the interventions locally.

National availability of influenza vaccine among medical subspecialty practices.

BACKGROUND: Influenza vaccination rates fall short of national goals, particularly among individuals whose chronic conditions predispose them to complications of influenza. Availability of influenza vaccine in medical subspecialists' practices may affect vaccination rates among adults with chronic illness. METHODS: The practice sites of a national random sample of medical cardiology, endocrinology, and pulmonology physicians were contacted by telephone in February 2003 to March 2003 to determine which of them had influenza vaccine available to their patients during the 2002-2003 influenza season. The number of physicians in the practice and geographic location were also obtained. RESULTS: Office staff at the practices of 1683 of 2013 eligible physicians were successfully contacted, and 1473 provided information about vaccine availability. Overall, 1094 (74%) of practices had influenza vaccine available during the 2002-2003 season. Availability differed significantly by subspecialty: 54% cardiology, 78% endocrinology, and 90% pulmonology (p<0.001). Influenza vaccine was more often available at subspecialists' practices in the Northeast (80%) than in the South (74%), Midwest (71%), and West (70%; p<0.005). In multivariate analyses, pulmonology practices in all census regions and sizes were significantly more likely to have influenza vaccine available than was the reference cardiology practice. Several endocrinology practice types also had significantly higher influenza vaccine availability than those in cardiology practice, particularly in multi-physician practices. CONCLUSIONS: Influenza vaccine availability varies widely across practices in the three medical subspecialties that provide care to the largest numbers of individuals with an indication for the vaccine in the United States. These findings have implications for the accessibility of influenza vaccine to individuals at high risk for morbidity and mortality associated with influenza.

One-year uptake of pneumococcal conjugate vaccine: a national survey of family physicians and pediatricians.

BACKGROUND: Pneumococcal conjugate vaccine (PCV7) was recommended by June 2000 for administration to all US children 25% of cases of otitis media. In multivariable logistic regression analyses of adoption of PCV7, FP who have higher proportions of African American patients and patients on Medicaid, see greater numbers of newborns, work in practices of >/=4 physicians, and are willing to consider administering at least 4 vaccine injections at 1 visit are significantly more likely to have adopted PCV7. Concerns about vaccine cost and reimbursement were the most commonly cited factors in physicians' decisions not to adopt PCV7 recommendations. CONCLUSIONS: One year after PCV7 was recommended, nearly all pediatricians and a majority of family physicians had incorporated this vaccine into their practices. Barriers to higher rates of uptake-especially among family physicians-must be addressed to achieve immunization goals with this new vaccine.

Influence of insurance status and vaccine cost on physicians' administration of pneumococcal conjugate vaccine.

OBJECTIVE: In 2000, heptavalent pneumococcal conjugate vaccine (PCV7) was recommended for children younger than 2 years, but its high cost relative to other universally recommended childhood immunizations and variability in insurance coverage for the vaccine raised concerns. We investigated the influence of PCV7 cost and insurance coverage on physician recommendation of PCV7 to their patients and administration of PCV7 in their practices. METHODS: We conducted a mail survey from April to July 2001 of a random sample of 833 pediatricians and 788 family physicians in 24 states with different vaccine financing strategies (Vaccines for Children [VFC]-only; enhanced VFC; universal purchase). Physicians specified the proportion of children in their practice with insurance coverage for PCV7, where they recommend administering PCV7, and whether they have concerns about the cost of PCV7. RESULTS: The response rate was 60%. Overall, 87% of physicians recommend PCV7 for children younger than 2 years (99% pediatricians; 68% family physicians). Among physicians who recommend PCV7, 98% said that they would administer the vaccine in their own practices for children whose insurance covers the vaccine. However, only 56% of physicians who recommend PCV7 reported that all children in their practices had insurance coverage for the vaccine, whereas 24% of physicians reported 86% to 99% of children with coverage and 20% reported

The value of community participation in disease surveillance: a case study from Niger.

A team of researchers, including one behavioral scientist (S.M.N.) and three epidemiologists (L.Q., O.S. and S.N.) conducted community analyses to assess the social and cultural factors that affect the detection and reporting of disease cases in a surveillance system, using acute flaccid paralysis (AFP) surveillance in Niger as a case study. Over a 60-day period in the country, the research team reviewed written field reports and interviewed epidemiologists, nurses, community members and persons in governmental and non-governmental organizations. Overall, we found that the logistical difficulties of travel and communication, which are common in developing countries, constrain the conventional surveillance system that relies on epidemiologists visiting sites to discover and investigate cases, particularly in rural areas. Other challenges include: community members' lack of knowledge about the possible link between a case of paralysis and a dangerous, communicable disease; lack of access to health care, including the low number of clinics and health care workers; cultural beliefs that favor seeking a local healer before consulting a nurse or physician; and health workers' lack of training in AFP surveillance. The quality of surveillance in developing countries can improve if a community-based approach is adopted. Such a system has been used successfully in Niger during smallpox-eradication and guinea worm-control campaigns. In a community-based system, community members receive basic education or more extensive training to motivate and enable them to notify health care staff about possible cases of disease in a timely fashion. Local organizations, local projects and local leaders must be included to ensure the success of such a program. In Niger we found sufficient quantities of this type of social capital, along with enough local experience of past health campaigns, to suggest that a community-based approach can improve the level of comprehensiveness and sensitivity of surveillance.
