A surge of COVID-19 cases at the University of California, Berkeley, has prompted school officials to extend a lockdown on about 2,000 students in residence halls and bar them from outdoor exercise.
The university says more than 400 mostly undergraduates have tested positive since an outbreak started in mid-January. A weekly breakdown shows about 200 positive tests since the start of February.
A lockdown initially put in place for Feb. 1-8 has been extended through at least mid-month. Among the strict new rules are a ban on outdoor exercise that goes beyond state guidelines encouraging people to get outside to exercise.
