(University of the Free State, 2021-12)Surveillance of mosquito-borne alphaviruses is critical for the prevention of diseases and the control of outbreaks caused by these viruses, especially with the absence of approved vaccines and antiviral treatments available. ... -
HBV viral load and drug resistance among HIV-HBV co-infected patients: a cross-sectional study in central South Africa
(University of the Free State, 2021-12)In South Africa, human immunodeficiency virus (HIV) infected individuals co-infected with hepatitis B virus (HBV) do not routinely undergo HBV viral load (VL) testing when on antiretroviral therapy in the public sector ... -
Whole genome analysis of rare and/or novel rotavirus strains post-Rotarix® introduction in Zambia
(University of the Free State, 2021-06)Background: Group A rotaviruses (RVA) cause acute diarrhoea in children under the age of five years. In sub-Saharan Africa, limited studies have been conducted on RVA at whole genome level, particularly post-vaccine ... -
Genetic analysis of human papillomavirus type 11 isolates from patients with recurrent respiratory papillomatosis treated at Universitas Academic Hospital
(University of the Free State, 2021-07)Human papillomavirus type 11 (HPV11) is a causative agent of recurrent respiratory papillomatosis (RRP), a common benign laryngeal neoplasm that presents mainly in children. The genome comprises three regions: the early ... -
Zoonotic diseases in high-risk populations in the Free State province, South Africa
(University of the Free State, 2021-05)Zoonotic diseases are infectious diseases transmitted from vertebrate animals to humans and are accountable for more than 60% of all recognized human diseases and 75% of all new or emerging infectious diseases (EID). In ... -
Whole-genome analyses of rotavirus strains circulating pre- and post- Rotateq™ vaccine introduction in Rwanda
(University of the Free State, 2020-09)Children living in developing countries are constantly faced with the burden of diarrheal infections that account for over 1.6 million death cases globally. Rotavirus group A (RVA) has been identified as one of the viruses ... -
Drug resistance mutations in newly diagnosed HIV-infected infants and in children and adolescents with virological failure on ART
(University of the Free State, 2020-12)Introduction and aim: South Africa has never experienced an epidemic of the same extent and magnitude as the one with human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS).The roll out of ... -
The distribution, patient characteristics, therapy and patient outcome in culture positive invasive mold infections in a tertiary hospital in the Free State province, South Africa
(University of the Free State, 2019)Introduction Fungi, including molds, are increasingly recognized as important pathogens carrying a high morbidity and mortality in critically ill and immune compromised patients and our understanding of these diseases ... -
Characterization of T cell responses to the non-structural proteins of the M segment in survivors of Crimean-Congo haemorrhagic fever
(University of the Free State, 2019-02)Crimean-Congo haemorrhagic fever orthonairovirus (CCHFV) is one of the most widely distributed arboviruses globally. The disease caused by the virus, Crimean- Congo haemorrhagic fever (CCHF), continues to emerge and re-emerge ... -
