Talked to a buddy of mine who is an EMT near San Diego.
Last Friday, an EMT crew from LA we called out to deal with 4 homeless people. They were lying under a bridge, completely unresponsive and sick as hell.
It brought up an interesting problem. The EMTs are trained to take homeless patients to the emergency room. ERs don't test for NCP unless you fit some specific criteria, most of which need to be communicated verbally. None of the patients were responsive, nothing would have triggered a test.
EMS in CA is freaked about this right now. Word gets around fast when there's a suspected case and there are areas with significant homeless populations that lack emergency services altogether. They're short staffed, there are people taking leave so they don't need to deal with this.
EMS deals with the homeless all the time, most preventative measures would fail. Even if you put people under quarantine, most of them have serious mental health issues and will harm themselves in custody. The risk to medics is high, if there's an outbreak, homeless people are not going to seek treatment until it's in an advanced stage. His ambulance has been attacked by large packs of homeless seeking drugs, he's had to shelter in place and wait for police while they tried to tip the ambulance. In the event of an epidemic, he thinks they would be key to the spread because there are no good options for getting them treatment.
The 4 patients from last Friday were diagnosed with pneumonia and transported to another hospital that could offer better critical care options. He hasn't heard anything about them since then, which raises this other question: how do you know if the hospitals are actually treating these people? When it comes to the homeless, LA has a bad record of treating the symptoms and releasing homeless people back on the street.
It's entirely possible that, right now, LA EMS could be getting infected bums, sticking them with an IV, and releasing them back into the wild. This is a very real fear people on the frontlines are dealing with.
