My cousin mid march had symptoms of high temperature, coughing and fatigue. As she is front line nursing staff she self isolated for 14 days.
Fortunately it wasn't her days to return to work for another 5 days. The day before she returned to work she went shopping etc.
Went back to work for 10 days.
Last week she was ill again her manager arranged for her to be tested which came back positive.
This means that if the first time she was ill(not tested) was covid it's over 28 days since then.
Last night she was admitted to hospital with breathing difficulty. Her husband is now also ill but not as bad to be admitted.
Maybe covid lasts longer than we thought.
