BACKGROUND: Robust monitoring and reporting systems for rabies are lacking thus increasing the risk of underreporting. Highlighting the rabies cases brings to bear the needed urgent attention for more efforts at preventing and controlling the disease.
OBJECTIVE: To describe the epidemiological characteristics of patients managed for clinical rabies at the largest referral facility in Ghana.
METHODS: A retrospective single-center hospital-based chart review and data extraction were conducted for persons managed for clinical rabies infection at the Korle-Bu Teaching Hospital from January 2008 to December 2019. Data analysis was done using STATA. Descriptive statistics were used to summarize the epidemiological and clinical characteristics. Fisher\'s exact test, the Kruskal-Wallis test, and Spearman\'s correlation coefficient were used to explore significant associations.
RESULTS: A total of 28 cases were recorded over the period of review. All of them died and most (68%) of them were males. Twenty-one percent of them were less than 15 years old. Their median age interquartile range (IQR) was 31 years (25.5 years) and the median incubation period for rabies (IQR) was 60 days (60 days). The source of rabies for cases was mainly dog bites. The vaccination status of all the animals could not be ascertained. Majority (80%) of the patients took neither anti-rabies vaccine nor immunoglobulin as post-exposure prophylaxis after the dog bite. The median time of admission before death (interquartile range) was 2 days (2 days). Majority (82%) of the cases were furious rabies.
CONCLUSIONS: Attention should be directed at mass vaccination of dogs as dog bites are common. Ensuring availability and access to post-exposure prophylaxis (PEP) is also critical in averting rabies-related deaths.
BACKGROUND: Des systèmes de surveillance et de déclaration robustes pour la rage font défaut, augmentant ainsi le risque de sousdéclaration. Mettre en lumière les cas de rage suscite l\'attention urgente nécessaire pour redoubler d\'efforts dans la prévention et le contrôle de la maladie.
OBJECTIVE: Décrire les caractéristiques épidémiologiques des patients traités pour une rage clinique dans le plus grand établissement de référence au Ghana.
UNASSIGNED: Une revue rétrospective des dossiers médicaux et une extraction de données basées à l\'hôpital ont été réalisées pour les personnes traitées pour une infection à la rage clinique à l\'Hôpital d\'Enseignement Korle-Bu de janvier 2008 à décembre 2019. L\'analyse des données a été effectuée à l\'aide de STATA. Des statistiques descriptives ont été utilisées pour résumer les caractéristiques épidémiologiques et cliniques. Le test exact de Fisher, le test de Kruskal-Wallis et le coefficient de corrélation de Spearman ont été utilisés pour explorer les associations significatives.
UNASSIGNED: Un total de 28 cas ont été enregistrés sur la période examinée. Tous sont décédés et la plupart d\'entre eux (68%) étaient des hommes. Vingt et un pour cent d\'entre eux avaient moins de 15 ans. Leur âge médian (plage interquartile) était de 31 ans (25,5 ans) et la période d\'incubation médiane de la rage (plage interquartile) était de 60 jours (60 jours). La principale source de rage pour les cas était principalement les morsures de chiens. Le statut vaccinal de tous les animaux n\'a pas pu être déterminé. La majorité (80%) des patients n\'ont pris ni vaccin antirabique ni immunoglobuline en prophylaxie post-exposition après la morsure de chien. Le délai médian d\'admission avant le décès (plage interquartile) était de 2 jours (2 jours). La majorité (82%) des cas étaient atteints de rage furieuse.
CONCLUSIONS: L\'attention devrait être dirigée vers la vaccination de masse des chiens car les morsures de chien sont courantes. Assurer la disponibilité et l\'accès à la prophylaxie post-exposition (PPE) est également crucial pour éviter les décès liés à la rage.
UNASSIGNED: Rage, morsure de chien, post-exposition, prophylaxie, vaccination de masse.

An infectious disease known as rabies (family Rhabdoviridae, genus Lyssavirus) causes severe damage to mammals\' central nervous systems (CNS). This illness has been around for a very long time. The majority of human cases of rabies take place in underdeveloped regions of Africa and Asia. Following viral transmission, the Rhabdovirus enters the peripheral nervous system and proceeds to the CNS, where it targets the encephalon and produces encephalomyelitis. Postbite prophylaxis requires laboratory confirmation of rabies in both people and animals. All warm-blooded animals can transmit the Lyssavirus infection, while the virus can also develop in the cells of cold-blooded animals. In the 21st century, more than 3 billion people are in danger of contracting the rabies virus in more than 100 different nations, resulting in an annual death toll of 50,000-59,000. There are three important elements in handling rabies disease in post exposure prophylaxis (PEP), namely wound care, administration of anti-rabies serum, and anti-rabies vaccine. Social costs include death, lost productivity as a result of early death, illness as a result of vaccination side effects, and the psychological toll that exposure to these deadly diseases has on people. Humans are most frequently exposed to canine rabies, especially youngsters and the poor, and there are few resources available to treat or prevent exposure, making prevention of human rabies challenging.

The \'One Health\' (OH) approach is the most promising idea in realising the global goal of eliminating canine-mediated human rabies by 2030. However, taking an OH approach to rabies elimination can mean many different things to different people. We conducted a systematic review scrutinizing economic evaluations (EEs) retrieved from MEDLINE OVID, Embase OVID, Global Health OVID, CINAHL EBSCO and ECONLIT EBSCO that used the OH approach with the intent of identifying cost-effective sets of interventions that can be combined to implement an optimal OH-based rabies elimination program and highlight key gaps in the knowledge base. Our review suggests that an optimal OH program to tackle rabies should incorporate mass dog vaccination and integrated bite case management in combination with efficient use of post-exposure prophylaxis along with a shift to a 1-week abbreviated intradermal rabies vaccine regimen in humans. We recommend that future EEs of OH interventions for rabies elimination should be performed alongside implementation research to ensure proposed interventions are feasible and adopt a wider societal perspective taking into account costs and outcomes across both the human health and animal welfare sectors. The systematic review has been registered with PROSPERO.

The current WHO-recommended rabies pre-exposure prophylaxis (PrEP) are two-visit vaccination schedules, but there are studies suggesting that single visit schedules might be sufficient to prime the immunity.
A literature review was conducted to retrieve and summarize published data on single visit rabies PrEP. PubMed database was screened for articles published between January 1st, 2003 and December 31st, 2022. The bibliographies of the articles chosen to undergo full text review and of the current major WHO publications on rabies were searched to find additional references, regardless of publication date. The primary outcome was the percentage of subjects having received rabies PrEP on single visit schedules who achieved antibody levels ≥0.5 IU/mL one week after post-exposure prophylaxis (PEP), regardless of the PEP regimen.
11 studies were selected for inclusion, totalling 935 subjects, of which 696 received a simulated PEP schedule. Of these 696, a serological test result on day 7 was available for 408 of them, and 406 subjects (99.51%) seroconverted after PEP without any difference regarding time delay between PrEP and PEP or the vaccination schedule used for PEP.
Single visit PrEP schedules seem to confer sufficient protection in most healthy individuals without immunocompromised status if a booster PEP is administered after a suspected rabies exposure. Further studies in real-life settings and in different age categories are needed to confirm this finding, which may increase the availability of vaccines and thus the accessibility of PrEP for vulnerable populations.

Rabies is a neglected zoonotic disease that can infect all mammals, including humans. We aimed to summarise the current knowledge of the incidence, risk factors and mortality of rabies in Southeast Asia.
Systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020.
Scopus, Web of Science and PubMed were searched from 1 January 2012 to 21 February 2023.
Original English language articles published between 2012 and 2023 were included.
Nine independent reviewers extracted data and assessed the risk of bias. The quality appraisal of included articles was carried out using the Mixed Methods Appraisal Tool.
A total of eight articles were included in this analysis. In Vietnam, the incidence of rabies ranged from 1.7 to 117.2 per 100 000 population. The cumulative incidence in Sarawak was estimated at 1.7 per 100 000 population. In Indonesia, 104 human rabies cases were reported from 2008 to 2010, while in Thailand, a total of 46 rabies cases were reported in Thailand from 2010 to 2015. In the Philippines, the incidence of rabies ranged from 0.1 to 0.3 per 100 000 population. An increased risk of rabies virus infection was associated with a high population density, illiteracy, seasonal patterns and dog butchers. The case fatality rate was 100%.
This study included research from Southeast Asia, which may not represent rabies infection in other regions or continents. In addition, the role of publication bias should be acknowledged as grey literature was not included. The occurrence of rabies in Southeast Asia is due to the high number of unvaccinated stray and pet dogs, working hazards (dog butchers in Vietnam), the unavailability of the rabies vaccine in rural regions and misinformation about the significance of seeking treatment after dog bites.

BACKGROUND: Rabies continues to be a serious threat to global public health endangering people\'s health and public health safety. In the People\'s Republic of China, multi-sectoral and comprehensive prevention and control strategies have aimed to extensively curb human rabies transmission. Here, we examine the current state of rabies infection in China, explore strategic interventions put in place in response to WHO\'s ambition of \"Zero rabies deaths by 2030\" and critically assess the constraints and feasibility of dog-mediated rabies elimination in China.
METHODS: This study analyzed and evaluated the process towards dog-mediated rabies elimination in China from five perspectives: namely, human, dog, policy, challenge, and prospects. Evidence-based data on progress of dog-mediated rabies elimination in China was derived from a number of sources; a literature search was undertaken using PubMed, Web of Science and CNKI databases, distribution data for human rabies cases as derived from the Data-center of the China Public Health Science and policy and document data were obtained from official websites of the relevant China ministries and commissions.
RESULTS: The incidence of human rabies cases in China have shown a downward trend year-on-year since 2007. Implementation of a government-led, multi-sectoral \"One Health\" approach to combating rabies has driven down the total number of rabies deaths nationwide to around 200 in 2020. The number of provincial-level administrative divisions (PLADs) reporting human cases of rabies has also decreased to 21 in 2020, 13 of which reported less than 10 cases. Furthermore, the number of outpatient visits seeking rabies post-exposure prophylaxis has risen dramatically over the past two decades, with demand being 15 times higher than it was initially. There remain however, significant gaps in rabies elimination outcomes across the different regions of China. To date the target of achieving a canine rabies vaccination rate of > 75% has not been met. The challenges of rabies immunization of dogs and dog management in underdeveloped cities and rural areas need to be addressed together with more effective animal surveillance and rabies risk from and too wildlife and livestock.
CONCLUSIONS: The Chinese government-led, multi-sectoral \"One Health\" approach to combating rabies and has made significant progress over the past decade. Development and adoption of more cost-effective One Health strategies can achieve more nationally beneficial rabies elimination outcomes. The ambitious target of \"Zero rabies deaths by 2030\" can be met through establishment of long-lasting herd immunity in dogs by means of dog mass vaccination campaigns, dog population management, epidemiological surveillance and the application of large-scale oral rabies vaccine to eliminate rabies in wild animals coupled with deployment of cost-effective human post-exposure prophylaxis, and community education.

Post-exposure prophylaxis (PEP) for rabies is widely administered and highly effective. Nevertheless, sporadic breakthrough infections (ie, rabies in people who have started PEP) have been reported. We conducted a systematic review of articles published between Jan 1, 1980 and June 1, 2022 to characterise breakthrough infections. After reviewing 3380 articles from across all continents, we identified 52 articles, which included a total of 122 breakthrough infections. We classified breakthrough infections on the basis of adherence to core practices (ie, wound cleaning and vaccine administration). Of 86 breakthrough infections with data, median time from exposure to symptom onset was 20 days (IQR 16-24). Most (89 [77%] of 115) participants received PEP within 2 days of an exposure. Severe wounds (defined as those involving multiple wound sites or bites to the head, face, or neck) were common (80 [69%] of 116 [with data]). Deviations from core practices were reported in 68 (56%) of 122 cases. Other possible causes for breakthrough infections included errors in the administration of rabies immunoglobulin, delays in seeking health care, and comorbidities or immunosuppression. Cold-chain integrity assessments and potency testing of PEP biologics were only rarely assessed (8 [7%] of 122 cases), neither of which were found to be a cause of breakthrough infections. Timely and appropriate administration of PEP is crucial to prevent rabies, and although people with high-risk exposures or immunosuppression can develop rabies despite adherence to core practices, this occurrence remains exceedingly rare.

Dog-maintained rabies virus variant (DMRVV) was eliminated in the United States in 2007. During 2015–2019, three dogs with rabies were imported into the United States from Egypt, where DMRVV is endemic. CDC developed a risk mitigation strategy, in consultation with a diverse group of subject matter experts, that permitted 296 dogs to be imported from Egypt during May 10, 2019–December 31, 2020, minimizing the risk for future rabid dog importations. The broadly vetted risk mitigation strategy, which included serologic testing for rabies antibody titer, improved CDC’s ability to ensure that imported dogs from Egypt posed no public health risk in the United States. This strategy could be used to guide future policy decisions regarding dog importations.

To evaluate the safety and immunogenicity of rabies vaccine for human use after post-exposure in China.
A systematic search was performed from PubMed, EMBASE, CNKI and Cochrane Library database, supplemented by manual retrieval. According to the inclusion and exclusion criteria, a meta-analysis was performed using Stata 16.0 software after independent literature screening, data extraction and quality assessment by two evaluators.
A total of 32 studies were included. It was found that rabies vaccination after PEP could induce the body to produce sufficient RVNA. Both Essen and Zagreb regimens showed good immunogenicity, with no significant difference in systemic events and local events after PEP, but a relatively high incidence of local and systemic events after PEP under the Zagreb regimen.
For the Chinese population, rabies vaccination after PEP has shown relatively a good immune efficacy and acceptable safety for preventing human rabies. The survey also found that the Zagreb regimen was comparable to the Essen regimen in terms of rabies prophylaxis with an acceptable safety profile.

This study comprehensively evaluated and compared three human rabies vaccines. Seven electronic databases were systematically searched. The Cochrane Handbook v5.1.0 was used to assess the risk of bias. A random-effects model was used to combine individual rates, and network meta-analysis was used for pairwise comparisons. Twenty-seven articles were included, with a total of 18,630 participants. The pooled incidence of the total adverse reaction to HDCV was significantly lower than that of PCECV. HDCV administration resulted in a lower incidence of local pain, fever, and weakness than purified Vero cell vaccine. HDCV caused a lower incidence of local pain and fever than PCECV. No significant difference was observed in terms of the seroconversion rate on day 7 or the rabies virus-neutralizing antibody titer on day 14. HDCV demonstrated superiority in terms of safety compared with the other two rabies vaccines, while the same was not observed in terms of immunogenicity.
