Re-emergence of chikungunya in the Republic of the Congo in 2019 associated with a possible vector-host switch.

In January 2019, an outbreak of Chikungunya virus fever was reported in a rural region near Pointe-Noire, Republic of the Congo. Molecular and phylogenetic analysis of this new CHIKV strain demonstrated the presence of the A226 V substitution and a surprisingly close relation with Aedes aegypti-associated Central Africa chikungunya strains. These results, combined with the preponderance of Aedes albopictus in the outbreak area, suggest a recent vector-host switch facilitated by the emergence and spread of...


Analysis of a vector-bias malaria transmission model with application to Mexico, Sudan and Democratic Republic of the Congo.

Malaria is a deadly disease transmitted to human through the bite of infected female mosquitoes. The aim of this paper is to study the different vector-bias values between low and high transmission areas with the examples of Mexico (low) and Sudan, Democratic Republic of the Congo (Congo, DR) (high) during malaria transmission. We develop a malaria transmission model with vector-bias and investigate the basic reproduction number, the existence of equilibria and the corresponding globally asymptotically stab...

Despite porous international borders and considerable population movement, however, transmission has been confined to North Kivu and Ituri provinces. Factors potentially contributing to this containment include co...

"Even if she's really sick at home, she will pretend that everything is fine.": Delays in seeking care and treatment for advanced HIV disease in Kinshasa, Democratic Republic of Congo.

HIV prevalence in the Democratic Republic of Congo (DRC) is estimated to be 1.2%, and access to HIV testing and treatment remains low across the country. Despite advances in treatment, HIV continues to be one of the main reasons for hospitalisation and death in low- and middle-income countries, including DRC, but the reasons why people delay seeking health-care when they are extremely sick remain little understood. People in Kinshasa, DRC, continue to present to health-care facilities in an advanced stage o...

Distribution of the cytochrome P450 2C8*2 allele in Brazzaville, Republic of Congo.

Cytochrome P450 (CYP) enzymes are essential in the metabolism of most drugs used today. Single nucleotide polymorphism(s) occurring in CYP genes can adversely affect drug pharmacokinetics, efficacy and safety. Individuals carrying CYP2C8*2 c.805A > T (CYP2C8*2; rs11572103) allele have impaired amodiaquine (AQ) metabolism, increased risk of amodiaquine - related adverse events and may promote selection of drug - resistant parasite strains. This study investigated the distribution of CYP2C8*2 alle...

A systematic review of individual and community mitigation measures for prevention and control of chikungunya virus.

Chikungunya is a mosquito-borne virus transmitted by mosquitoes from the Aedes genus. The virus, endemic to parts of Asia and Africa, has recently undergone an emergence in other parts of the world where it was previously not found including Indian Ocean Islands, Europe, the Western Pacific and the Americas. There is no vaccine against chikungunya virus, which means that prevention and mitigation rely on personal protective measures and community level interventions including vector control.

Genetic landscape and macro-evolution of co-circulating Coxsackieviruses A and Vaccine-derived Polioviruses in the Democratic Republic of Congo, 2008-2013.

Enteroviruses (EVs) are among the most common viruses infecting humans worldwide but only a few Non-Polio Enterovirus (NPEV) isolates have been characterized in the Democratic Republic of Congo (DR Congo). Moreover, circulating vaccine-derived polioviruses (PVs) [cVDPVs] isolated during multiple outbreaks in DR Congo from 2004 to 2018 have been characterized so far only by the sequences of their VP1 capsid coding gene. This study was carried to i) investigate the circulation and genetic diversity of NPEV an...

Whole-gene analysis of inter-genogroup reassortant rotaviruses from the Dominican Republic: Emergence of equine-like G3 strains and evidence of their reassortment with locally-circulating strains.

Inter-genogroup reassortant group A rotavirus (RVA) strains possessing a G3 VP7 gene of putative equine origin (EQL-G3) have been detected in humans since 2013. Here we report detection of EQL-G3P[8] RVA strains from the Dominican Republic collected in 2014-16. Whole-gene analysis of RVA in stool specimens revealed 16 EQL-G3P[8] strains, 3 of which appear to have acquired an N1 NSP1 gene from locally-circulating G9P[8] strains and a novel G2P[8] reassortant possessing 7 EQL-G3-associated genes and 3 genes f...

Update on Vaccine-Derived Poliovirus Outbreaks - Democratic Republic of the Congo and Horn of Africa, 2017-2018.

Widespread use of live attenuated (Sabin) oral poliovirus vaccine (OPV) has resulted in marked progress toward global poliomyelitis eradication (1). However, in underimmunized populations, extensive person-to-person transmission of Sabin poliovirus can result in genetic reversion to neurovirulence and paralytic vaccine-derived poliovirus (VDPV) disease (1). This report updates (as of February 26, 2019) previous reports on circulating VDPV type 2 (cVDPV2) outbreaks during 2017-2018 in the Democratic Republic...

Hepatitis B infection among pregnant and post-partum women living with HIV and on antiretroviral therapy in Kinshasa, DR Congo: A cross-sectional study.

Hepatitis B virus (HBV) co-infection in HIV-infected individuals increases the risk of hepatic complications and mortality. Further, the risk of perinatal HBV transmission increases among HBV/HIV co-infected pregnant women. Although HBV is endemic in the Democratic Republic of Congo, there is little data on HBV/HIV co-infection. We aimed to assess the burden and risk factors of HBV surface antigen (HBsAg) positivity among HIV-infected pregnant and post-partum women.

From 2015 to 2017, a total of 677 imported malaria cases were detected and 76 P. ovalespp. isolates were identified, of which 48 were P. ovale curtisi and 28 P. ovale wallikeri. The number of P. ovale...

Do patients from the Democratic Republic of Congo with schizophrenia have facial emotion recognition deficits?

Patients with schizophrenia can have difficulty recognizing emotion, and the impact of this difficulty on social functioning has been widely reported. However, earlier studies did not thoroughly explore how this deficit may vary according to emotion intensity, or how it may differ among individuals and across cultures. In the present study, our aim was to identify possible deficits in facial emotion recognition across a wide range of emotions of different intensities among patients with schizophrenia from t...

Emergence and re-emergence of mosquito-borne arboviruses.

Arthropod-borne viruses (arboviruses) are ecologically distinct from many other pathogens because of the involvement of arthropod vectors and animal reservoirs. Several mosquito-borne arboviruses have emerged in various geographic regions during the past few decades. Since the beginning of the 21st century, the emergence of two mosquito-borne arboviruses, chikungunya and Zika, has taken place globally. Millions of infections have not only changed the epidemiology of previously obscure viruses, but also put ...

"So that's why I'm scared of these methods": Locating contraceptive side effects in embodied life circumstances in Burundi and eastern Democratic Republic of the Congo.

Contraceptive side effects (SE) are often portrayed as either unproblematic trade-offs for pregnancy prevention or misconceptions and fears that negatively affect individuals' contraceptive decisions. Little attention is given, however, to wider, socially-rooted meanings and rationales for these feared and experienced SE. Through inductive analysis of in-depth interviews conducted with women and men from rural Burundi and South Kivu province, Democratic Republic of the Congo between 2013 and 2016, we locate...
