Abstract

BackgroundIn the Democratic Republic of the Congo, the international support was suddenly withdrawn after the massacre of students at the Lubumbashi University in May 1990. The interruption of the international aid from 1990 to 1991 would undoubtedly have a long-lasting negative effect on case load. So, the National Sleeping Sickness Control Programme--NSSCP (Programme National de Lutte contre la Trypanosomiase Humaine Africaine) (PNLTHA) remains vulnerable without international aid. Currently, the number of reported new cases decreased. These achievements prove that the elimination of this neglected tropical disease is possible when there is a strong commitment of public authorities accompanied by scientific research centers, civil society and the private sector. Without international aid, sleeping sickness remains a formidable disease difficult to cure because it is depending on continued financial support and drug availability.\n\nObjectivesThe objectives of this work were: 1. to profile the incidence of new cases of human African trypanosomiasis in the Democratic Republic of the Congo from 2002 to 2003, depending on the stage of disease progression (stages 1 and 2); 2. Compare the evolution of this profile from one household to another; 3. Compare the rate of confirmed parasitological diagnosis with positive CATT; 4. Calculate the discrepancy rate between CATT+ and parasitological diagnosis. All the above objectives are aiming to sustain the efforts made for the adoption of the 2018 Francophonie resolution on the ridding of human African trypanosomiasis that may renewed donor interest, including the government of the Democratic Republic of the Congo because the control of HAT is completely dependent on international aid.\n\nMethodsResearch is necessary on how to rationalize control activities so that control programs can adopt the most effective and efficient strategies. To assess it, we analyzed epidemiologic data collected by PNLTHA from 2002 to 2003.\n\nResultsIn all endemic areas, 1,970,101 people were tested in 2002 and 2,311,507 people in 2003. The national average coverage of the total population tested (TPT) represents 16.20% of the exposed population among which 13,853 new cases were detected in 2002 and 11, 481 new cases detected in 2003 with the national average coverage of the population tested that represents 19.10 %.\n\nConclusionIn short, we said that the number of people already infected is probably higher than the new cases reported in 2003. We are still far from the situation of 1958/60 when there was 1 new case declared by 10,000 people tested (i.e. 1,100 new cases out of 13,000,000 people screen). Therefore, the Congolese government must make long-term financial commitments to ensure the continuity of HAT control activities.\n\nAuthor summaryFor the past three decades, the frequency of sleeping sickness tends to become a large in the Democratic Republic of the Congo. This paper reviews the status of sleeping sickness in DRC between 2002 and 2003, with a focus on stage patterns. Epidemiological trends at the national and provincial level are presented. Today, this deadly fly-borne disease threatens more than 65 million people worldwide and most of the reported cases (more than 8 out of 10) are in the Democratic Republic of the Congo. Fortunately, after decades of hard work, we have never been so close to eradicating sleeping sickness in the Democratic Republic of the Congo. In 2009, the number of reported cases fell below 10,000, the first in half a century. In 2015, only 2,804 cases had been listed. The Democratic Republic of the Congo is determined to eradicate the disease by 2020, paving the way for its global eradication. Thanks to these decades of work. I submit this inquiry to recognize also the work that my last mentor coauthor of this search did, he hold his doctorate on this disease. This submission is an appropriate way I found to honor and keep the memory of my supervisor who passed away! In advance, many thanks for your best understanding of this particular circumstance. From my last mentor work, we have never been so close to the definitive elimination of sleeping sickness. The number of reported new cases decreased from 26,318 in 1998 to 11,481 in 2003 and later to 2,804 in 2015. These achievements prove that the elimination of neglected tropical diseases is possible when there is a strong commitment of public authorities accompanied by scientific research centers, civil society and the private sector.

Factors associated with cholera outbreaks, Nairobi County, July 2017: a case control study

BackgroundCholera affects 1.3-4 million people globally and causes 21000-143,000 deaths annually. Nairobi County in Kenya reported cholera cases since April 2017. We investigated to identify associated factors and institute control measures.\n\nMethodsWe reviewed the line-list of patients admitted at the Kenyatta National referral Hospital, Nairobi and performed descriptive epidemiology. We carried out a frequency-matched case control study, using facility-based cases and community controls. We defined a case as acute onset of watery diarrhoea of at least >3 stools/24hours with or without vomiting in person of any age, admitted in Kenyatta National Hospital as from July 1st, 2017. We calculated odds ratios and their respective 95% confidence intervals. We also took water samples at water reservoirs, distribution and consumer points, and made observation on hygiene and sanitation conditions in the community.\n\nResultsWe reviewed 71 line-listed cases; median age 30 years (range 2-86 years); 45 (63%) were male. First case was admitted on 14th April 2017. Culture was performed on 44 cases, 30 (68%) was positive for Vibrio cholerae, biotype El-Tor, serotype Ogawa. There were 2 deaths (case fatality ratio 2.8%). Age-group [≥]25 years was most affected. Drinking unchlorinated water (aOR 14.57, 95% CI 4.44-47.83), eating in public places (aOR 9.45, 95% CI 3.07-29.12) sourcing water from non-Nairobi city water company source (aOR 4.92, 95% CI 1.56-15.52) and having drank untreated water in the previous week before the outbreak (aOR 3.21, 95% CI 1.12-9.24) were independently associated with being a case in the outbreak. Out of 28 water samples, 4 (14%) had >180 coliforms/100mls; all were at consumer points.\n\nConclusionPoor water quality and sanitation were responsible for this outbreak. We recommended adequate, clean water supply to unplanned settlements in Nairobi County, as well education of residents on water treatment at the household level.\n\nAuthor summaryCholera, a disease causing outbreaks in areas with low standards of hygiene and sanitation has afflicted humans for millennia. It is caused by a bacterium, Vibrio Cholerae, transmitted mainly through water contaminated by faecal matter. The resultant disease is acute watery diarrhoea, which causes death rapidly due to dehydration and shock. Virtually brought under control in the developed world due to improvements in hygiene, the disease still ravages many communities in low and middle income countries, as well as regions affected by conflict or natural disasters. In outbreak situations, rapid response in water treatment, sanitation improvement and setting up of cholera treatment centres for rehydration therapy reduces impact and saves lives. Long-term control can only be achieved through sustainable improvements in sanitation and standards of living. Case control studies in outbreak situations provide quick, actionable information to public health specialists during outbreak response. This study provides a cholera outbreak investigation in an urban informal settlement setting; the approach reported here can guide in outbreak investigations and response in similar settings globally.

Infection of Borrelia burgdorferi sensu lato of small mammals in Yunnan Province, China

BackgroundLyme disease is caused by Borrelia burgdorferisensulato (BBSL) which is usually found in wild and domestic mammals worldwide. Human cases of B. burgdorferi infections have been identified in China, but little direct surveillance of potential rodent reservoirs has been performed in Yunnan Province, Southwestern China. Yunnan Province is a tropical area with a diverse topographic range and sustains a high biodiversity of small mammals that could potentially play an important role in the transmission of a variety of B. burgdorferigenospecies.\n\nMethods3659 small mammals were captured in 159 sample siteslocated 23 countries inYunnan Province and screened for BBSL infection by nested PCR based on 5S-23S rRNA intergenic spacer gene of BBSL.Univariate and multivariate forward stepwise logistic regression analysis was used to access the association between infections and related risk factors.\n\nResultsInfection with BBSL was confirmed in 3.99%(146/3659) of small mammals. Significant differences in prevalence rates of BBSL were observed at varying landscape types and altitudes.Small mammals in forested areas had higher prevalence rates than other landscape types as did small mammals found at altitudes greater than 2500 meters. The 5S-23S rRNA intergenic spacergene revealed that there were 5 genotype of BBSL, including B. afzelii, B. burgdorferisensustricto, B.japonica, B.gariniiand B.valaisiana, which demonstrate the genetic diversity and regional distribution.\n\nConclusionsThere exists a wide distribution and genetic diversity of endemic BBSL in Southwestern China, warranting further investigations and monitoring of clinical disease in individuals presenting with symptoms of Lyme disease in these areas.\n\nAuthor summaryLyme disease is caused by Borrelia burgdorferi sensu lato (BBSL) which is usually found in wild and domestic mammals worldwide. Human cases of Borrelia burgdorferi sensu lato infections have been identified in China, but little direct surveillance of potential rodent reservoirs has been performed in Southwestern China. This study documents potential small mammal reservoir hosts collected from a large of sample sites from different landscape types and altitudes, with PCR and sequencing identifying the wide distribution and genetic diversity of endemic Borrelia burgdorferi sensu lato in Southwestern China. This was the first report that B. japonica was detected in Apodemus draco and Niviventer excelsior in China. This study adds to body of literature on Borrelia burgdorferi sensu lato in China. This work will provide insight regarding small mammals to target for surveillance and we access the association between gender, developmental stage of rodents, environmental landscape and altitude to better prevent human exposure.

Interdependence between confirmed and discarded cases of dengue, chikungunya and Zika viruses in Brazil: A multivariate time-series analysis

The co-circulation of different arboviruses in the same time and space poses a significant threat to public health given their rapid geographic dispersion and serious health, social, and economic impact. Therefore, it is crucial to have high quality of case registration to estimate the real impact of each arboviruses in the population. In this work, a Vector Autoregressive (VAR) model was developed to investigate the interrelationships between discarded and confirmed cases of dengue, chikungunya, and Zika in Brazil. We used data from the Brazilian National Notifiable Diseases Information System (SINAN) from 2010 to 2017. There were three peaks in the series of dengue notification in this period occurring in 2013, 2015 and in 2016. The series of reported cases of both Zika and chikungunya reached their peak in late 2015 and early 2016. The VAR model shows that the Zika series have a significant impact on the dengue series and vice versa, suggesting that several discarded and confirmed cases of dengue could actually have been cases of Zika. The model also suggests that the series of confirmed and discarded chikungunya cases are almost independent of the cases of Zika, however, affecting the series of dengue. In conclusion, co-circulation of arboviruses with similar symptoms could have lead to misdiagnosed diseases in the surveillance system. We argue that the routinely use of mathematical and statistical models in association with traditional symptom-surveillance could help to decrease such errors and to provide early indication of possible future outbreaks. These findings address the challenges regarding notification biases and shed new light on how to handle reported cases based only in clinical-epidemiological criteria when multiples arboviruses co-circulate in the same population. Author summaryArthropod-borne viruses (arboviruses) transmission is a growing health problem worldwide. The real epidemiological impact of the co-circulation of different arboviruses in the same urban spaces is a recent phenomenon and there are many issues to explore. One of them is the misclassification due to the scarce availability of confirmatory laboratory tests. This establishes a challenge to identify, distinguish and estimate the number of infections when different arboviruses co-circulate. We propose the use of multivariate time series analysis to understand how the weekly notification of suspected cases of dengue, chikungunya and Zika, in Brazil, affected each other. Our results suggest that the series of Zika significantly impact on the series of dengue and vice versa, indicating that several discarded and confirmed cases of dengue might actually have been Zika cases. The results also suggest that the series of confirmed cases of chikungunya are almost independent of those of dengue and Zika. Our findings shed light on yet hidden aspects on the co-circulation of these three viruses based on reported cases. We believe the present work provides a new perspective on the longitudinal analysis of arboviruses transmission and call attention to the challenge in dealing with biases in case notifications when multiple arboviruses circulate in the same urban environment.
