Johannesburg is a major travel hub, so it’s no surprise that news of hantavirus cases linked to international travel has caused unease among some residents.
Over the weekend, reports emerged that three travellers who had been aboard a vessel sailing from Argentina to Cape Verde died after contracting hantavirus. One additional patient, believed to be linked to the same vessel, is currently receiving treatment in an intensive care unit at a Johannesburg hospital, in Sandton.
According to the World Health Organisation (WHO), one case has been laboratory-confirmed, while five others remain suspected.
'To date, one case of hantavirus infection has been laboratory confirmed, and there are five additional suspected cases. Of the six affected individuals, three have died, and one is currently in intensive care in South Africa, the World Health Organisation states on X.
What does this mean for Johannesburg?
Despite concerns, health authorities have stressed that there is no need for widespread panic. Hantavirus is primarily contracted through exposure to infected rodents, specifically their urine, droppings, or saliva.
Human-to-human transmission is extremely rare, which significantly limits the likelihood of a broader outbreak in an urban setting like Johannesburg.
How to reduce your risk
The most effective way to prevent infection is to minimise contact with rodents and their waste. This includes:
* Keeping homes and workspaces clean and free of food debris
* Sealing holes or gaps that may allow rodents to enter
* Using traps where necessary
* Experts also advise against sweeping or vacuuming rodent waste, as this can release harmful particles into the air. Instead, contaminated areas should be sprayed with disinfectant before cleaning.
Recognising the symptoms
Early symptoms of hantavirus infection can resemble those of the flu. According to the WHO, these include fatigue, fever, and muscle aches. As the illness progresses, individuals may experience headaches, dizziness, chills, nausea, vomiting, diarrhoea, and abdominal pain.
Officials monitoring the situation
South Africa’s Health Minister, Aaron Motsoaledi, is expected to brief the media as authorities continue to monitor developments.
For now, officials maintain that while vigilance is important, especially in densely populated areas, there is no immediate cause for alarm.
