Paramore has postponed their concert dates in Jakarta and Manila due to lead vocalist Hayley Williams' struggle with a "throat and upper-respiratory infection."

Williams explained the entire situation in a lengthy note posted on social media on Friday afternoon.

"I wanted to write personally to tell you that I've been fighting a throat & upper-respiratory infection for the last 2 days," she wrote.

"It's a pretty nasty sickness but if I would've been able to get my voice to come through for me, the guys and I would've done the show tonight anyway. Unfortunately, my throat hasn’t loosened up and the rest of my symptoms have only gotten worse."

"After getting an official diagnosis from a doctor, our team decided that it would be the right thing to postpone the show tonight in Jakarta as well as the next show in Manila to later this year."

She added that the Manila concert has been rescheduled to August 23, and urged fans to "hold on to your tickets if you already have them."

She also wrote: "Just to be transparent - the reason for also delaying the Manila show is to reduce the amount of travel we’d have to do within the next few days of the tour.

"We’ve been flying a LOT on this tour. Traveling by plane can make it hard to heal because of the dry, recycled air, the extreme altitude, and the fact that planes are basically just flying petri dishes. Minimizing flights and having those few extra days off should give my antibiotics time to kick in and allow my voice time to recover from all this coughing."

She concluded her note by saying: "I'm so sorry for the disappointment this will inevitably cause everyone who's been looking forward to these two shows. I know nothing I say will alleviate that letdown..."

"We were so ready to get back to Manila because every show we’ve played for our Filipino friends has been a wild time. We're coming back for you so please hang on 'til August."

The Sunday concert at the Mall of Asia Arena would have been the band's third performance in the country, following their 2010 and 2013 shows. The date is part of a tour promoting their new album, "After Laughter."
