baka wala pa silang result sa sarili nilang test sa dexamethasone kaya di pa sila nag bibigay ng persmission para gamitin ito sa mga covid-19 patients. it is important that they have their own result to see if it is safe to use to covid-19 patients. but I agree na mabagal sila kumilos.
I don't think they are really trying the dexamethasone treatment. Wala lang talaga silang interest para subukan ito, last few months ago pa na news yung drugs and dapat may result na siya kung gumawa sila ng testing (I hope I'm wrong here though).
