TEHRAN  Iran’s health ministry on Sunday raised the nationwide death toll from the new coronavirus to 54 as the number of confirmed infected cases jumped overnight by more than half to 978 people. The ministry’s spokesman KianoushJahanpour said new cases were confirmed in a number of cities, including Mashhad, which is home to Iran’s most important Shiite shrine that attracts pilgrims from across the region. Calls by Iran’s civilian government to clerics to close such shrines to to the public have not been uniformly followed. The shrine in Mashhad is among those that have remained open. The new figures represent 11 more deaths than reported on Saturday and a whopping 385 new cases of infections. The new numbers, however, bring down the percentage of deaths to infections to around 5.5%. Still, that is much higher than other countries, suggesting the number of infections in Iran may be much higher than current figures show. Jahanpour said in his daily briefing that the number of cases is “still inclining” across Iran. Of the 385 newly confirmed cases, 170 are in Tehran, where schools and cinemas have remained closed for the second week. Public buses and the metro are still operating, but are being disinfected daily there. Authorities also doused busy streets in the capital.
