Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

Viral hepatitis is defined as inflammation of the liver cells due to viral infection. The burden of liver disease in South Africa is mostly underestimated as viral hepatitis, in particular chronic infection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease i...s likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

Surgical site infections (SSI) are a serious problem globally; they are the most frequent type of health care-associated infection (HAI) observed on admission in low- and middle-income countries (LMICs). Approximately one in 10 people who have surgery in LMICs acquire an SSI, and SSI is reported as ...the second most common HAI in Europe and the United States of America. Therefore, it is crucial to include SSI prevention activities in your overall IPC programme.
