There's a really important point in this article:

Hydroxychloroquine should be administered at the very beginning of the disease, from the 2nd to the 4th day of the appearance of the first symptoms, such as fever, cough, runny nose and breathing more than 22 times per minute. People who manifest this condition should receive the medication at home. The drug is inexpensive and has few side effects.

The Ministry of Health focuses on testing, which can be a mistake, due to the need to treat quickly. The test takes time without taking action; it is an obstacle disguised as treatment. The focus should be tomography, soon after suspicion (cough / fever). If it is altered (ground glass), the doctor should use Hydroxychloroquine.

They aren't waiting for a positive COVID-19 test. They are instead going right to a CT scan and starting treatment if it shows damage to the lungs. I presume the "ground glass" refers to the appearance of the damage to the lungs.

Unfortunately, sending someone for a CT isn't instant unless you are at a hospital. We may have the advantage of faster testing, once the Cepheid and Abbott test kits are widely distributed. Those report results in 45 minutes and 15 minutes. But, the real advantage is the systems are already widely deployed in the US, in doctor's offices and clinics. Right now, a large part of our testing bottleneck is the requirement to ship the sample to a lab. Even though they might have a high-throughput Roche system, it's still a bottleneck.
