A 39-year-old woman died on Saturday while trapped in the blizzard that has engulfed the N3 between Van Reenen's Pass, connecting KwaZulu-Natal and the Free State.

This was confirmed by paramedic services, Midlands EMS [emergency medical services] Rescue Medics, in a statement.

According to the medical service, the Midlands EMS Howick crews, along with Midlands EMS Rescue Medics, were dispatched to a shopping centre in Merrivale for a person who had collapsed after being exposed to severe cold overnight, while in a taxi stuck in traffic in the snow.

The person was a passenger on the taxi travelling from Johannesburg towards KwaZulu-Natal. The taxi had stopped for refreshments when the incident occurred.

"Upon arrival, it was found that the individual had collapsed and was in a critical state of hypothermia, requiring urgent medical care.

"While en route to the hospital, the patient's condition rapidly deteriorated. Full resuscitation efforts were performed but sadly, the patient was pronounced deceased upon arrival at the hospital," reads the statement.

uMgungundlovu District Municipality and its sector departments have expressed their "deepest regret" for this tragic incident.
