Up to now the most recommended action to take when a person exhibits COVID-19-like symptoms has been to quarantine until s/he develop serious respiratory problems, and then take them to hospital where they're put on ventilation. This is counterproductive and in most cases, fatal

Like every other disease out there, doctors have been recommending early treatment of COVID as soon as the first typical symptoms appear. This is the best way to prevent the progression of the disease into serious pneumonia

Important to note that COVID-19 is said to have an incubation period of 14 days, so by the time one starts showing symptoms, the viral load (amount of virus in the blood) is already at a maximum which leaves little time for an early treatment regime...

So, people who live in "COVID hotspots" should consider starting prophylactic (preventative) treatment with their doctor, and may not want to wait to take a PCR test first. Most doctors recommend the following treatment regime. Of course, your doctor will advise accordingly

If one has already started showing symptoms of COVID-19, they are often left with only a few days left to react to the infection with an early treatment intervention. But there's still hope, and doctors recommend the following regimen. Again, always speak to your doctor first

Early treatment is recommended as a way to avoid having to go to hospital, however, if it becomes necessary for one reason or another, ICU doctors recommend avoiding getting on invasive ventilation, but using oxygen therapy (High Flow Nasal Cannula) instead

The mortality profile of COVID is "essentially 0 for children and young adults and near 0 for anyone below 50".
It only begins to be serious above 70 - 80, meaning all these pharmaceutical interventions are basically redundant for anyone under 50, but it might save grandpa
