New coronavirus pneumonia and SARS are both coronaviruses, but because the level of medical and social development in 2003 was very different from that of now, the two diseases should not be comparable. 2003 SARS lacked the equipment for rescuing critically ill patients, so SARS gave people the impression that it was more violent, and at that time, there were more serious illnesses, and it was also considered that the mortality rate was relatively high and treatment was more difficult. And now, although the incidence rate is very high, the proportion that really causes serious illness is not particularly high, so from the current summary, it is slightly milder than the coronavirus infection in 2003. But it’s still too early to draw conclusions, because the situation is still evolving every day, and it’s still necessary to wait for the final summary after the epidemic has completely passed to determine the difference between this pneumonia and SARS.
