How do imported malaria cases influence transmission and antimalarial drug resistance in South Africa’s elimination districts? Malaria remains a major public health concern globally, despite being both preventable and curable. In 2024, an estimated 282 million malaria cases were reported worldwide, with Africa continuing to carry the overwhelming burden of disease transmission. South Africa, located
How do provincial differences shape the burden and characteristics of invasive pneumococcal disease in South Africa? Invasive pneumococcal disease (IPD), caused by Streptococcus pneumoniae, remains a significant public health concern in South Africa, particularly among infants, older adults, and individuals with underlying conditions. While the introduction of pneumococcal conjugate vaccines (PCVs) into the Expanded Programme
Can improved surveillance and treatment access reduce the burden of cryptococcal disease in South Africa? Cryptococcal disease is a serious fungal infection caused by Cryptococcus species, most commonly affecting people with weakened immune systems. In individuals living with HIV, particularly those with advanced disease, the infection can spread to the brain and cause cryptococcal meningitis,
What do the latest GERMS-SA surveillance findings reveal about disease trends in South Africa? Infectious diseases caused by bacterial, fungal, and parasitic pathogens remain a major public health concern. Surveillance systems that rely on laboratory-confirmed cases provide critical insights into disease burden and epidemiology, but can be affected by disruptions in diagnostic and reporting capacity.
