BNP Chairperson Khaleda Zia finally tested negative for Covid-19, 27 days after she had been infected with the deadly virus.  “Madam (Khaleda) underwent the Covid test on Saturday and her report came out negative,” the BNP chief’s medical board member Dr AZM Zahid Hossain told UNB early Sunday. Another physician of her medical board said, “Madam is still being given oxygen support though her overall condition marked a little improvement. Her oxygen level is coming down to 90 percent when there's no oxygen support,” he said. The physician, wishing anonymity, said though the amount of fluid in her lungs has decreased, It's still being extracted from her lungs which is now a matter of concern. He said the BNP chief’s blood sugar level is gradually coming under control while pain in her joins has relieved significantly.
