The Eastern Cape health department has asked patients who usually use the New Brighton Clinic to make alternative arrangements for the next two to three days.
Health spokesman Siyanda Manana said repairs were being done at the clinic following a break-in on Sunday evening – the second in a week.
In both instance, copper piping was stolen, however Sunday’s incident left the clinic completely flooded.
Manana referred patients to the Tshangana Clinic, also in New Brighton.
The department aims to re-open the clinic by Thursday.
Meanwhile Manana said the department would be taking a hard look at security at clinics around Nelson Mandela Bay following a spate of incidents.
Last week, nurses at Veeplaas Clinic refuse to work following a stabbing incident.
In August, two security guards and a supervisor were also beaten up for their cellphones at the Zwide Clinic.
