Olabisi Onabanjo University Teaching Hospital (OOUTH) Sagamu has shut its main medical laboratory unit after 14 more workers tested positive for coronavirus.

The Nation reports that a wave of mass infections hit the teaching hospital with 20 staff testing positive as at last Friday.

One of them was said to have infected three members of his family, prompting the management to shut the Laboratory unit.

However, it was gathered that 14 out of 16 staff in the laboratory tested positive, which a source described as second wave of mass infection at the health facility.

This brings the total number of infected staff to 34, including a family of four; the wife of one of the lab workers and his three children.

Commissioner for Health Dr Tomi Coker confirmed that the laboratory has been shut for two weeks but declared the statistics of affected laboratory workers remained a private affair.

A laboratory staff, who craved anonymity, on Wednesday, told journalists workers in the facility had been going for COVID-19 test since last Friday, following the death of a staff while some were already ill and manifesting symptoms associated with COVID-19.

The source blamed the incident on insensitivity of the management of the teaching hospital to the plights of dealing with COVID-19 patients.
