Can an employee divulge personal health information regarding another employee?

If an employee divulges this information to their manager, is the manager then able to discuss this information with other employees?

For example:
Employee A is HIV+. Employee A confides in a fellow employee (Employee B) about their status because they believed they were friends, and honest and trustworthy.

Employee B then gets mad at Employee A and divulges that fact that Employee A has AIDS and cleaned the restroom without wearing gloves, to their director. Is Employee B at fault for divulging this information to their director (that fact that an employee is HIV+)? Is the director able to question other employees regarding Employee A's health status? Is it a violation for the employer to ask employees if they knew Employee A had AIDS and cleaned without gloves? (it should be stated that the employee does not have AIDS, but is HIV+) Can the director discuss Employee A's health status with another director, and then confront Employee A's supervisor, and director and ask if said employee has AIDS?

I believe the most tactful way for Employee B and their director to have handled this, was by stating Employee A did not use gloves while cleaning. There was no need to have mentioned that Employee A had AIDS (which is not true because Employee A is HIV+). By divulging the fact that Employee A had AIDS, I believe, oversteps a boundry and perhaps violates HIPPA.

Thoughts and Feelings on this subject matter please!!

The manager/director represents the company. The fellow employee told the manager/director, who in turn passed on the information to others that fact that Employee A has AIDS (when in fact Employee A is HIV+)

I agree. The privacy act is for health care professionals and I believe Druggists. But since the person told the other about his or her condition it is all water under the bridge

Employee to employee there is nothing that can be done. But if it had been the employer then it would of been different. Best thing to do as and employee with a major medication condition is to keep it to yourself. Do not trust anyone that you work with, more then likely these people are not trustworthy.

HIPAA applies ONLY to health care providers and the information THEY can divulge about patients. Private individuals in discussions with other private individuals have NO such protection. Choose with whom you share such information cautiously.
