On 30 May 2022, WHO donated 900 oxygen cylinders with regulators and humidifiers to the Ministry of Health and Sanitation as a response to the need for oxygen in public health facilities across Sierra Leone. This is because the COVID-19 pandemic exposed gaps in the Sierra Leone health system's ability to respond adequately to patient needs, especially the provision of life-saving medical oxygen. Each of the cylinders been donated can hold 40 litres of oxygen. The total cost of the donation cost more than USD200 000.
