Tokyo confirmed 87 new novel coronavirus cases on Nov. 2, the first day the count fell below 100 since Oct. 19, officials said.

The number of newly confirmed infections tends to be lower on Mondays than other days of the week because of the fewer tests conducted in the previous few days.

It normally takes about three days for the results of polymerase chain reaction tests to be confirmed and compiled by the Tokyo metropolitan government.

Tokyo reported 78 new COVID-19 cases on Oct. 19, also a Monday.

The metropolitan government said the number of serious cases requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, decreased by two from the previous day to 32 on Nov. 2.

Officials also corrected the number of people who contracted the virus that the government announced in the past, as the cumulative COVID-19 cases in the capital decreased by six.

Corrections were made due to testing errors and inconsistencies.

Three-time Olympic gold medal gymnast Kohei Uchimura who tested positive for the virus but tested negative on a second PCR test appears to be one such case.

Officials lowered the daily count of new infection cases on July 13 from 119 to 118. They reduced the number on Oct. 7 from 141 to 140 and the tally on Oct. 24 from 203 to 201.

The number of new cases on Oct. 29 was lowered from 221 to 220 and on Oct. 30 from 204 to 203.
