Abstract Background The Rotavirus Gastroenteritis (RVG) is a contagious vaccine-preventable disease that contributes to the high morbidity and mortality among under 5 children. In Yemen, Rotavirus Surveillance System (RVS) was launched in 2007 as sentinel surveillance and the vaccine was introduced in 2012. However, the current protracted conflict led to a significant breakdown of health services including immunization and water, sanitation and hygiene. The aim is to describe the pattern of RVG during the conflict time: 2014-2019. Methods 2014-2019 RVS data that covers demographic variables, clinical symptoms, vaccination status and laboratory results were analyzed using Epi.info 7.2. Results 6,663 suspected RVG cases were reported. The most affected age group was 9-12 months and cases were higher among males (59%). RVG shows a seasonal pattern where RVG was predominantly reported in the cold season. Only 24% needed admission due to severe dehydration. Only 65% of cases were vaccinated, of them 85% received two doses. The case fatality rate was 1.1%, and was significantly higher among unvaccinated (1.8 vs. 0.6%, P < 0.0001). Of the 5,875 samples collected, only one third found positive to Rotavirus where the predominant genotypes were G12 P [8] and G 2 P [4]. Conclusions The findings highlight that RVG is still an ongoing cause of morbidity among under 5 children in Yemen that upsurges with the low Rotavirus immunization coverage. Therefore, boosting immunization coverage together with other diarrhea prevention strategies are required. Furthermore, ongoing surveillance is important to monitor the RVG epidemiology and to evaluate vaccine effectiveness against the currently circulating genotypes. Key messages It is First research about rota that done in Yemen during conflict so it gives opportunity for future increased scientific rigor, outcomes-focused research, and health informatics. It provides policy makers by recommendation for improving public health and surveillance system during crisis.

Abstract Background Diphtheria is a contagious vaccine-preventable disease that contributes to the high morbidity and mortality among under 5 children, especially in Yemen. As a consequence of war and collapse of the health system, a fatal epidemic occurred at the end of 2017. This study aims to describe the epidemiology of diphtheria by time, place, and person and vaccination status of affected children. Methods A study was conducted in Sada'a governorate by using accumulative line list of diphtheria from November 2017 to September 2020 at electronic Integrated Disease Early Warning System (eIDEWS). The case definition of WHO was adopted. Data was analyzed by Microsoft Excel and Epi info- version 7.2 and multivariable logistic analysis used for identifying significant associated factors. Results 747 cases were met of WHO case definition. The annual peak of cases started during week 31 and weak 49. Males were slightly more than females (51% vs 49%) and about 35% of cases involved children aged 10 to < 15 years. The overall incidence of diphtheria and case fatality rate (CFR) were 69/ 100,000 and 6.4%, respectively. The highest CFR was among age groups under 5 years 11% (P < 0.001) and among females was 8%. Dysphagia and swollen lymph nodes were the predominant symptoms 98%, 92%, respectively. Based on the Vaccination status, the percentage of unvaccinated and unknown were 53% and 41% respectively, with CFR 11% among cases who received one dose. Furthermore, the most case were from Sahar 40% with case fatality rate 8% and the highest CFR was significantly higher among cases in border and ongoing conflict district (P < 0.05). Conclusions The findings highlight that diphtheria is still an ongoing cause of morbidity and mortality among under 5 children in Sada'a that is rising with the low diphtheria immunization coverage. Therefore, concomitant efforts should now focus on improving and monitoring routine immunization across all age groups and healthcare services, especially in borders and continuing conflict districts.

Few epidemiological studies have been undertaken of measles disease among Sudanese, although measles is the third leading cause of death since 1995 among childhood diseases that can be prevented by immunization. The measles vaccine was introduced into the EPI program in 1985. In the run-up to the introduction of the vaccine, the country suffered from measles epidemics periodically and extensively, ranging from 50,000 to 75,000 cases and from 15,000 to 30,000 deaths per year. Simple actions can save a million lives of children through immunization coverage, eye care programs, maternal and child health education, maintaining and improving the general nutritional status of Sudanese children. Continuous surveillance and monitoring systems and evaluation are essential tasks at all levels to improve performance, identify and address problems throughout establishing and increasing the surveillance system. This review highlights a brief overview of measles epidemiology in Sudan and determinants of a measles outbreak, clinical symptoms, complications, and surveillance sites and the ways for prevention and control of measles disease. The review established that it is crucial to enforce coordination between governmental and non-governmental agencies for an effective disease surveillance system in the area, especially in those affected by civil wars.

SUMMARYSapovirus, a member of the family Caliciviridae, is one of the major causative agents of viral gastroenteritis affecting all age groups. A total of 3232 faecal specimens collected from infants and children with gastroenteritis in five different regions of Japan during 2003–2009 were examined for sapovirus by reverse transcription–polymerase chain reaction. Sapoviruses were detected in 131 (4·05%) patients with the peak observed mainly in the cold season (November–March) in Japan during 2003–2009. During the last 6 years, sapovirus GI/1 was the predominant strain in Japan followed by GIV, GII/3, GII/6, GII/2, GII/12 and GI, respectively.

Introduction: In 2019, we investigated the profile of the cases and controls and the determinants of pertussis transmission in Kebbi State, Northwestern Nigeria, to inform better immunization and surveillance strategies. Methods: Community-based unmatched case–control study and review of the 2019 pertussis routine surveillance data in the affected settlements in the state were conducted. A total of 52 suspected cases of pertussis and 107 control from two local government areas in Kebbi State were recruited. Data were analyzed using descriptive and inferential statistics. Results: The highest attack rate was observed among between 1- and 4-year age group followed by children less than 1-year old, and the least attack rate was among those above 15 years. The overall attack rate and the case fatality rate were 2.10% and 0.10%, respectively. A higher attack rate was observed among women, whereas the case fatality rate was more among males. From the community survey, we observed that the cases were less likely to have pertussis vaccination history (adjusted odds ratio = 0.28, 95% confidence interval = 0.11–0.74) compared with the controls. Knowing pertussis prevention methods were found protective for pertussis transmission (adjusted odds ratio = 0.14, 95% confidence interval = 0.04–0.45). Conclusion: This study showed the vulnerability of children under 5 years, especially under 1 year, to vaccine-preventable diseases in rural populations, where “real” immunization coverage is sub-optimal, and the dominant socio-demographic factors are supportive of disease transmission. We found immunization and knowledge of the preventive measures to be protective against pertussis outbreaks. Therefore, routine immunization services must be intensified to improve coverage and prevent future pertussis outbreak(s).

Introduction: Tetanus accounts for high morbidity and case fatality rates in developing countries. This study therefore aimed to identify reasons for the persistence of this disease. Methodology: Paediatric admissions at Ladoke Akintola University Teaching Hospital between 1 January 2006 and 31 December 2008 diagnosed with tetanus were studied. Data was analyzed with SPSS 18 and statistical significance was set at p < 0.05. Results: Of the total 1,681 paediatric admissions, 30 (1.8%) had tetanus. Of the 878 neonatal admissions, 8 (0.9%) had tetanus, while 22 (2.7%) of the total 803 post-neonatal admissions had tetanus. Neonatal tetanus admissions were significantly higher in 2006 compared to 2007 and 2008 (7 [2.3%] versus 1 [0.2%] [χ2= 7.50, P=0.01]). Of the eight mothers whose neonates had tetanus, seven did not receive tetanus toxoids in pregnancy and five (62.5%) were secondary school dropouts. Post-neonatal tetanus cases admitted in the years 2006, 2007, and 2008 were 4, 12, and 6 children respectively. Most of these 22 children did not receive tetanus toxoid immunization in their first year of life. None of the 22 children received booster doses of tetanus toxoids after their first years of life. Conclusion: Mothers at risk of their babies having tetanus, such as secondary school dropouts, must be identified antenatally and vaccinated with tetanus toxiod. Their babies should also receive good care post-delivery. Completion of routine tetanus toxoid schedule in the first year and booster doses in the post-neonatal age should be ensured.

Background: We evaluated the pneumonia surveillance system in Tema Metropolis to determine whether it is meeting its objectives and to assess its attributes.Design: Descriptive primary and secondary data analysisData Source: We interviewed health staff on the system’s operation and resources. We also extracted 2012-2016 surveillance dataset for under-five pneumonia cases and deaths from the District Health Information Management System for review.Participants: Health staffIntervention: The Centers for Disease Control (CDC) updated guidelines for evaluating surveillance systems was used to assess system attributes. Main outcome measure: state of the pneumonia surveillance system in TemaResults: A suspected case was defined as fast breathing in any child < 5 years old. The case definition was easy to apply, even at the community level. From 2012 to 2016, a total of 3,337 cases and 54 deaths (case fatality rate 1.6%) was recorded from 13 (23.6%) of 55 health facilities. Two epidemics were missed by the district because data were not being analysed. There were no laboratory data on antimicrobial resistance. Although reporting timeliness increased from 28.1% in 2012 to 83% in 2016, data inconsistencies existed between reporting levels.Conclusion: The surveillance system for under-five pneumonia in Tema Metropolis is simple, stable, flexible, timely,but of low sensitivity and acceptability, and only partly meeting its objectives. Major shortcomings are lack of laboratory data, non-use of data and low representativeness.Keywords: Under-five Pneumonia, Surveillance System Evaluation, Tema, GhanaFunding: The study was supported by a grant to author DB by the President’s Malaria Initiative (PMI) -CDC CoAg 6NU2GGH001876

Reports regarding brain inflammation, known as encephalitis, have shown an increasing frequency during the past years. Encephalitis is a relevant concern to public health due to its high morbidity and mortality. Infectious or autoimmune diseases are the most common cause of encephalitis. The clinical symptoms of this pathology can vary depending on the brain zone affected, with mild ones such as fever, headache, confusion, and stiff neck, or severe ones, such as seizures, weakness, hallucinations, and coma, among others. Encephalitis can affect individuals of all ages, but it is frequently observed in pediatric and elderly populations, and the most common causes are viral infections. Several viral agents have been described to induce encephalitis, such as arboviruses, rhabdoviruses, enteroviruses, herpesviruses, retroviruses, orthomyxoviruses, orthopneumovirus, and coronaviruses, among others. Once a neurotropic virus reaches the brain parenchyma, the resident cells such as neurons, astrocytes, and microglia, can be infected, promoting the secretion of pro-inflammatory molecules and the subsequent immune cell infiltration that leads to brain damage. After resolving the viral infection, the local immune response can remain active, contributing to long-term neuropsychiatric disorders, neurocognitive impairment, and degenerative diseases. In this article, we will discuss how viruses can reach the brain, the impact of viral encephalitis on brain function, and we will focus especially on the neurocognitive sequelae reported even after viral clearance.

The experience of pregnant and postpartum patients continues to evolve during the COVID-19 pandemic. Limited clinical data and the unknown nature of the virus’ impact and transmission routes have forced constant changes to traditional care delivery. Dependence on telehealth technology such as telephonic and videoconferencing has surged, and patients’ willingness to visit traditional health care facilities has plummeted. We set out to create an ongoing surveillance system to monitor changes to prenatal and obstetric care and the patient experience during the COVID-19 pandemic.

Measles continue to be a major public health issue worldwide with high morbidity and mortality rates. The disease is still endemic in Europe and during 2017 a vast outbreak was described in Italy, Romania and Hungary, which led to thousands of new cases and several deaths. In Italy, 3931 confirmed cases of measles were reported to the Italian national surveillance system from many Italian administrative regions; Lazio, in central Italy, exhibited the highest number of infected patients 1322 (33.63%) and as well as the highest incidence. In this study, we describe the results of a retrospective analysis, carried out during 2016 and 2017, concerning the measles antibody prevalence in patients and healthcare workers attending the Sant’Andrea Hospital of Rome (Lazio). A total of 94 patients (median 30 years of age) were screened in 2016, and 316 (median 40 years of age) during 2017, with an increase of 236% compared to previous year. During 2017, 41 confirmed cases of measles were reported while none in 2016 (P<0.007), and we found a suboptimal immunization coverage in our cohort of patients. Furthermore, measles surveillance of Sant’Andrea healthcare workers during the study period involved 208 personnel units (median >47 years of age) and only one confirmed measles infection was recorded in 2017. These results suggest that there is still an unvaccinated portion of the adult population, who sustain the endemic circulation of measles in Italy. In addition to reach herd immunization on children of 2 years old, catch-up vaccination campaign targeting adult population in Italy and other European countries needs to be implemented to prevent future measles outbreak.

Crimean Congo Haemorrhagic Fever

Crimean–Congo haemorrhagic fever (CCHF) is a severe disease with a case fatality of 2.8 to 80 %. A patient dwelling in an endemic region for CCHF was admitted with fever preceding bleeding diathesis and pancytopenia. Despite no history of tick exposure, CCHF was highly suspected. With an oral ribavirin therapy, clinical and laboratory improvements were obtained. The diagnosis was confirmed by detection of IgM antibody to CCHF virus and positive RT-PCR. Although the main pathogenesis of CCHF infection is not elucidated yet, haemophagocytosis, a symptom rarely reported in viral haemorrhagic fevers, was observed in this case. Haemophagocytosis is suggested to have a role in the development of pancytopenia in CCHF, the mechanism of which still needs to be investigated, probably with cytokine studies. Together with clinical symptoms and patient history, haemophagocytosis may be an indicator for CCHF.
