You seem to be missing both the growth rate curve and the time lag. If anything the US still has its head in the sand and is heading for 5-40 million deaths due to just swamping the hospital capacity for critical care.
That said. Italy basically denied having a problem until they couldn't anymore. China's safety net health system did everything they could to cover up the crisis until it exploded in their face. Other countries haven't been doing much more to prepare than the US.
People like to hate on it, but the US government still functions are a comparatively high level while maintaining a degree of individual freedom that other countries do not.
