Several limitations of our study need to be highlighted. Our case series is an observational convenience case series in which infection was confirmed with various (locally approved) PCR platforms. Persons in this case series had symptoms that led them to seek medical care, which implies that persons who were asymptomatic, had milder symptoms, or were paucisymptomatic could have been missed. Established links between persons receiving preexposure HIV prophylaxis and sexual health clinics and between persons living with HIV infection and HIV clinics could have led to a referral bias, especially given the potential for early care seeking in these groups. Spread to other populations is anticipated, and vigilance is required. Symptoms were recorded from the time of presentation, and therefore early symptoms may have been underreported, limiting information on the incubation period.
