A suspected case of measles. A rabid fox on the loose. A recall of a dye used in tattoos. A drug epidemic that's claiming hundreds of lives.

Those are just a few of the problems that Dr. Leana Wen confronts in a typical week as the Baltimore City Health Commissioner. While they all have to be dealt with, it's clear that heroin is among Wen's gravest concerns. Right now, she's focused on stopping overdoses and saving lives.

City officials are reopening East Baltimore's Safe Streets program, which closed in July when guns and drugs were found stashed in the office.

Baltimore Health Commissioner Dr. Leana S. Wen, who administers the anti-violence program, said city officials have done a comprehensive review of the McElderry Park site. That has led to "new training and security protocols to strengthen management and oversight," she said.

Baltimore City Health Commissioner Leana Wen took part in different events across the city as a part of International Overdose Awareness Day.  That included attending Naloxone training at a few of the 16 different Dontdie.org stations.
