Before Wednesday, the highest figure recorded by Lagos was 183 cases, which were confirmed on May 7, 2020.
The spike in the number of cases, which began in April 2020, has been attributed to increased testing capacity, as well as significant community-based transmission.
According to the NCDC breakdown on number of tests carried out by states, Lagos alone accounted for 41 percent of tests in Nigeria with 14,886 out of a total of 35,983 samples tested as of May 17, 2020.
