Are there therapies available to treat covid-19?

Yes: There are various therapies being used by none has yet to be found to be 100% effective. Some are felt to slow down virus replication. Some are felt to shorten length on ventilators or hospital stays. I don't think there's any therapy that can do what antibiotics can do such as kill bacteria which infect our body. One reason is that bacteria are outside our cells while viruses are within our cells

Treatment protocols: When ask about therapies - are you inquiring about COVID 19 treatment protocols? Different facilities have different Protocols. The DoD protocol is very helpful. However, if you are asking about medications - none have been shown to cure COVID 19 at this time.
