The Texas health department says a second health-care worker in Dallas has tested positive for Ebola.

The unidentified worker was part of the team that treated Thomas Duncan, the first Ebola victim in North America. After reporting a fever, the patient was isolated immediately.

The hospital says 75 other workers are being monitored for symptoms.

The diagnosis comes as the largest nurses’ union in the United States says it has received complaints that Dallas Presbyterian Hospital has not trained its staff in treated Ebola or given them proper equipment.

National Nurses United says hospitals are not being compelled to follow guidelines set out by the US Centres for Disease Control. The NNU says there is no enforcement or penalties in place to ensure the guidelines are followed. The union claims that Duncan was left in a general emergency room for hours, and staff did not have adequate protective clothing while treating him.

The CDC also admits that it did not do enough to control the possible spread of the virus in the Dallas hospital.

A similar complaint is coming from Canada’s largest nurses’ union. The Canadian Federation of Nurses’ Unions has written to Canada’s Chief Public Health Officer to say its members do not have the training or equipment to identify or treat Ebola. The CFNU says five unnamed Ontario Hospitals recently failed an Ebola Readiness Test.

Tests on a suspected Ebola case in Belleville indicate the patient does not have the virus.
