[Correspondence] Monkeypox virus–HIV co-infections in Sierra Leone

The ongoing monkeypox virus clade IIb outbreak in Sierra Leone has caused over 4800 confirmed cases in the first half of 2025, 5% of which are in children.1 Although the infection in most patients is not severe, mpox is often debilitating and life-threatening for those with advanced HIV disease. Caring for these patients is medically challenging and heartbreaking in equal measure.
