The way the WHO measures "best" is guaranteed to produce skewed results. A true measure of "best" is how well sick people fare after diagnosis. On that criterion the US has the best health care system i nthe world.
Again, the ratings are low simply because "universal health care coverage" is a major factor.
Look at how well people fare once they've been diagnosed, the only meaningful measure, and the US is far and away the best healthcare system.
How did the guy who got Ebola fair when he was diagnosed the first time.

Duncan's illness in Dallas[edit]

Texas Presbyterian Hospital, where Duncan was treated
Duncan began experiencing symptoms on September 24, 2014, and arrived at the
Texas Health Presbyterian Hospital emergency room at 10:37 p.m. on September 25.
[26] At 11:36 p.m., a triage nurse asked Duncan about his symptoms, and Duncan reported feeling "abdominal pain, dizziness, nausea and headache (new onset)."
[26] The nurse recorded a fever of 100.1 °F (37.8 °C), but did not inquire as to his travel history as this was not triage protocol at the time.
[26] At 12:05 a.m., Duncan was admitted into a treatment area room where the on-duty physician accessed the
electronic health record (EHR). The physician noted nasal congestion, a runny nose, and abdominal tenderness. Duncan was given Extra Strength
Tylenol at 1:24 a.m.
[26] CT scan results came back noting "no acute disease" for the abdominal and pelvic areas and "unremarkable" for the head.
[26] Lab results returned showing slightly low
white blood cells, low
platelets, increased
creatinine, and elevated levels of the liver enzyme
AST.
[26][27] His temperature was noted at 103.0 °F (39.4 °C) at3:02 a.m. and 101.2 °F (38.4 °C) at 3:32 a.m. Duncan was diagnosed with
sinusitis and abdominal pain and sent home at 3:37 a.m. with a prescription for
antibiotics, which are not effective for treating
viral diseases.
