Meet the amazing cast behind a life-changing drug

It was well after midnight in San Francisco when Eugenio (“Geno”) de Hostos picked up the phone—but when his colleagues in China answered, he felt the familiar jolt of excitement. He’d felt the same thrill at dawn, talking to his colleagues in Switzerland. At five, in a call to Maryland with the US Food and […] ; ; ; ;Related StoriesWaking from sleeping sickness in the DRCThe surprising consequences of tuberculosisPATH is at SXSW ;

Lessons from the front lines

In the midst of the 2014 Ebola outbreak in West Africa, a 21-year-old Guinean student came to a Dakar health clinic with symptoms of fever and diarrhea. The doctor considered Ebola, which had killed more than 1,000 people in neighboring Guinea. But the patient wasn’t bleeding. He denied having been in contact with Ebola patients […] ; ; ; ;Related StoriesIn Davos, Rx for epidemics: tech partnershipsInnovation is at the heart of SeattleOur 8 favorite photos of 2016 ;

by Fanny Nadia Dissak-Delon, Guy-Roger Kamga, Perrine Claire Humblet, Annie Robert, Jacob Souopgui, Joseph Kamgno, Marie José Essi, Stephen Mbigha Ghogomu, Isabelle Godin Background The fight against onchocerciasis in Africa has boomed thanks to the Community Directed Treatment with Ivermectin (CDTI) program. However, in Cameroon, after more than 15 years of mass treatment, onchocerciasis prevalence is still above the non-transmission threshold. This study aimed to explore a possible association between people’s beliefs/perceptions of onchocerciasis and of CDTI program, and their adherence to ivermectin in three regions of Cameroon

An economic evaluation of vector control in the age of a dengue vaccine

by Christopher Fitzpatrick, Alexander Haines, Mathieu Bangert, Andrew Farlow, Janet Hemingway, Raman Velayudhan Introduction Dengue is a rapidly emerging vector-borne Neglected Tropical Disease, with a 30-fold increase in the number of cases reported since 1960. The economic cost of the illness is measured in the billions of dollars annually. Environmental change and unplanned urbanization are conspiring to raise the health and economic cost even further beyond the reach of health systems and households

Endothelial activation and dysfunction in severe fever with thrombocytopenia syndrome

by Xiao-Kun Li, Zhen-Dong Yang, Juan Du, Bo Xing, Ning Cui, Pan-He Zhang, Hao Li, Xiao-Ai Zhang, Qing-Bin Lu, Wei Liu Background Pathogenesis of severe fever with thrombocytopenia syndrome (SFTS) has not been well described yet. Recent studies indicate that SFTSV could replicate in endothelial cells. Here we performed a case-control study to determine whether endothelial activation/dysfunction occurred in SFTSV infection and to identify the biomarkers reflecting endothelial dysfunction.

Asymptomatic and Sub-Microscopic Malaria: a Challenge to Elimination Efforts

WHO says that, “In settings where malaria is actively being eliminated or has been eliminated, a “case” is the occurrence of any confirmed malaria infection with or without symptoms.” Several recent studies describe the importance of paying attention to asymptomatic infections. In the Bagamoyo District of Tanzania Sumari and colleagues collected blood samples and examined them for Plasmodium falciparum prevalence using rapid diagnostic test (RDT), light microscopy (LM) and reverse transcription quantitative PCR. While overall prevalence was higher in symptomatic children using all three methods, asymptomatic children had a higher prevalence of gametocytes using light microscopy and PCR.  They concluded that, “The higher gametocytemia observed in asymptomatic children indicates the reservoir infections and points to the need for detection and treatment of both asymptomatic and symptomatic malaria.” The health effects of asymptomatic plasmodial infections (API) on children were documented in Rwanda. These included “Plasmodium infection was associated with anaemia, fever, underweight, clinically assessed malnutrition and histories of fever, tiredness, weakness, poor appetite, abdominal pain, and vomiting” and were generally more common with submicroscopic infection
