Ebola was spread by certain cultural practices like mourners set a funeral washing the body. Ebola is not air bourne, it's spread through bodily fluids like sweat, blood, faetes, vomit, spermicide etc. In west Africa there is not just a lack of doctors, but a lack of money to pay those doctors. Many Ebola victims are nursed at home in the slum they live in. The slums have no proper sewage and maybe very crowded.
I don't believe Pauline would choose to put her family's lives at risk. Would a nurse really want to risk their loved ones dying of Ebola?
I feel the issue was lack of organisation of public health England. A flight from west Africa carrying 300 people needs more than four nurses to check everyone's safety. Telling extremely tired volunteers to check their own temperatures was pure laziness.
I feel public health England should also be held up to account for their decisions on that day. (The managers of the four public England nurses, not the four nurses themselves.)
NHS Managers often put blame on to frontline staff to deflect blame from their own failings.
