My interpretation would be that the rate of survival is 53%; 348/(305+348). People don't die immediately, the ones currently infected can go either to the "Recovered" figure or the "Deaths" figure.
From the link above:
14628 are currently infected(?)
305 were infected and died
348 were infected and recovered
