“This is another fake news,” he tweeted, saying such claims, which have been circulating on social media, was misleading the public.

Noor Hisham also uploaded a screenshot of the message, albeit a partial one, that was making rounds on WhatsApp.

According to the message, Noor Hisham had tendered his resignation.

“Finally, Dr Noor (Hisham) has put his foot down. The daily figures for Covid-19 are backlogged from last year,” it read.

A few days ago, Noor Hisham confirmed that the recent spike in Covid-19 cases had been caused by a backlog in case reporting, including positive cases detected in 2020.

“There were also delays in reporting through the public health laboratory information system by registered private facilities, such as private clinics and hospitals,” he had said.
