Volkswacht Bodensee - UK's Queen Camilla reveals she had pneumonia

The 77-year-old made the comments at a reception for the state visit of Qatar's emir Sheikh Tamim bin Hamad Al-Thani.

Camilla missed last month's Remembrance Day commemoration events due to the chest infection.

She returned to duties on November 12, but has opted to skip the outdoor activities planned for the two-day Qatari state visit beginning on Tuesday as she is suffering from post-infection fatigue.

"She has lost the coughing but the lingering side of it is bouts of extreme tiredness," a royal source told the domestic Press Association.

It is the latest health scare for the family.

Catherine, Princess of Wales, only recently returned to the public eye after ending a course of chemotherapy, having announced her cancer diagnosis in March.

The shock announcement came after the palace had revealed the previous month that Charles had been diagnosed with an undisclosed cancer and would withdraw from public life to undergo treatment.

Both have since made limited returns to public duties, but Charles -- who recently toured Australia and Samoa -- is still undergoing treatment.
