Gauteng Premier David Makhura says there has been an increase in the number of cases in the province in the last seven days.
During a Gauteng Provincial Command Council update on Friday, he said the province had recorded 1 516 new coronavirus cases and four deaths in the past 24 hours.
Once people test positive, our tracing team has to immediately track contacts to contain the spread," said Makhura.
"The West Rand is our area of great concern, especially in the mining areas of the Merafong Municipality.
Five people are on ventilators, with one person in a public hospital and four in private hospitals.
