Agree in principle with remote diagnostics in this way. But, the number of acute illnesses that can be diagnosed with US and can/should be treated at home is fairly small. Pneumonia cannot be detected by US unless it is up against the chest wall (or perhaps if it causes excess fluid in the pleural space). An otitis media diagnosis would not be possible with US. Appendicitis can be seen with US but it is very operator-dependent and asking parents to fish around for the appendix would be a big ask (even with some rather advanced AI assistance). You can certainly find enlarged lymph nodes but fingers are often just as good.
