Introduction:Infectious disease surveillance has long been a challenge for low-income countries like Sierra Leone.Traditional approaches based on paper and Short Message Service(SMS)were subject to severe delays in obtaining,transmitting,and analyzing information.Methods:During the China aid operation for fighting Ebola since the end of 2014,a mobile electronic surveillance system for infectious diseases(MESSID)was developed in collaboration with the Republic of Sierra Leone Armed Forces(RSLAF),which comprised an Android-based reporting system and a complementary web-based program designed by Active Server ***(***)with the main functions including surveillance,real-time reporting,and risk assessment of infectious diseases.Results:MESSID was successfully registered in June 2016 and had been used by all medical and health institutions in RSLAF.From June 1,2016 to July 5,2021,34,419 cases were diagnosed with 47 infectious diseases of 5 categories,with a total of 42 clinical symptoms.Compared to traditional approaches based on paper and SMS,the MESSID showed flexibility,high efficiency,convenience,and acceptability.Discussion:MESSID is an accessible tool for surveillance of infectious diseases in Sierra Leone and possibly in other African countries with similar needs,capable of improving timeliness of disease reporting,thus rendering a timely outbreak detection and response.

BACKGROUND The Republic of Sierra Leone is located on the west coast of Africa,bordering Guinea and Liberia,with a population of 7.8 million in 2019(1).It has a tropical monsoon climate,with high temperatures and plentiful precipitation.As one of the least developed countries in the world(2),Sierra Leone has long struggled with poor health outcomes with a life expectancy at birth of 59 for male and 61 for female,and high maternal and neonatal mortality,threatened by infectious diseases such as malaria,tuberculosis,typhoid fever,cholera,and Lassa fever(3).

Since the outbreak of Ebola virus disease(EVD)in three countries in West Africa,China CDC has conducted two phases of technical cooperation projects based on the Sierra Leone-China Friendship Biological Safety Laboratory(SLE-CHN BSL-3 Lab)in the Republic of Sierra Leone(1-2).Phase Ⅰ was conducted from July 2015 to June 2017,while Phase Ⅱ started in July 2017 and will continue to June 2020.In total,85 Chinese public health specialists have been dispatched to Freetown,the capital city of Sierra Leone,with 80 serving for 6 months and 5 serving for a year.Most Chinese staff came from China CDC and the remaining roughly 15%came from different provincial-level CDCs.This report summarizes major developments to Sierra Leone’s public health field and comments on experiences obtained from the joint effort.

Objective People in Western Africa suffer greatly from febrile jaundice, which is caused by a variety of pathogens. However, yellow fever virus(YFV) is the only pathogen under surveillance in Sierra Leone owing to the undeveloped medical and public health system there. Most of the results of YFV identification are negative. Elucidation of the pathogen spectrum is required to reduce the prevalence of febrile jaundice. Methods In the present study, we used Ion Torrent semiconductor sequencing to profile the pathogen spectrum in archived YFV‐negative sera from 96 patients in Sierra Leone who presented with unexplained febrile jaundice. Results The most frequently identified sequencing reads belonged to the following pathogens: cytomegalovirus(89.58%), Epstein‐Barr virus(55.21%), hepatitis C virus(34.38%), rhinovirus(28.13%), hepatitis A virus(20.83%), coxsackievirus(10.42%), Ebola virus(8.33%), hepatitis E virus(8.33%), lyssavirus(4.17%), leptospirosis(4.17%), chikungunya virus(2.08%), Crimean‐Congo hemorrhagic fever virus(1.04%), and hepatitis B virus(1.04%). Conclusion The distribution of sequencing reads suggests a broader spectrum of pathogens for consideration in clinical diagnostics and epidemiological surveillance in Sierra Leone.

Background:The 2014-2016 Ebola virus epidemic in West Africa was the largest outbreak of Ebola virus disease(EVD)in history.Clarifying the influence of other prevalent diseases such as human immunodeficiency virus infection and acquired immune deficiency syndrome(HIV/AIDS)will help improve treatment and supportive care of patients with EVD.Case presentation:We examined HIV and hepatitis C virus(HCV)antibody prevalence among suspected EVD cases from the Sierra Leone-China Friendship Biological Safety Laboratory during the epidemic in Sierra Leone.HIV and HCV antibodies were tested in 678 EVD-negative samples by enzyme-linked immunosorbent assay.A high HIV prevalence(17.6%)and low HCV prevalence(0.22%)were observed among the suspected cases.Notably,we found decreased HIV positive rates among the suspected cases over the course of the epidemic.This suggests a potentially beneficial effect of an improved public health system after assistance from the World Health Organization and other international aid organizations.Conclusions:This EVD epidemic had a considerable impact on the public health system and influenced the prevalence of HIV found among suspected cases in Sierra Leone,but also provided an opportunity to establish a better surveillance network for infectious diseases.

投影仪散焦技术克服了实时光栅投影三维测量中的投影仪非线性问题,但散焦产生的高次谐波会大大降低散焦光栅的正弦性,带来明显的测量误差。提出了采用"S"形扫描Sierra Lite抖动算法生成二值抖动光栅,较大地改善了散焦后光栅的正弦性,将该抖动技术生成的散焦光栅用于传统的相移算法,基于投影仪散焦投影,得到用于三维测量的绝对相位信息。仿真结果验证了该方法的有效性,改善了散焦光栅的正弦性,提高了相位质量。实际测量实验与仿真结果相一致。与已有的Bayer有序抖动和Floyd-Steinberg抖动生成的光栅相比,所提算法运算速度快,生成光栅正弦性较好,更加适用于散焦投影测量。
