Hi, think about how everyone concerned may be affected, eg an outbreak of food poisoning, how this would affect residents/service users: those directly affected; sickness, diarrhoea, stomach cramps, dehydration ( may lead to being admitted to hospital) long-term complications, immune system being compromised, they may have existing health issues, be less able to fight off infections, or be vulnerable due to their age/lifestyle/circumstances.
People who live wtih individual/know them/attend the same day centre: not physically affected but emotionally: anxiety, stress, worry: will they be next? how ill are their friends?
Family & friends; worry, scared, will the person be ok? Financially affected.
Staff, they may be physically affected themselves, also feelings of guilt: were they responsible/what did they do/could of done, staff reputation, staff morale, short-staffed, extra pressure, stress, blaming those responsible.
The organisation; consequences, (reputation, investigation, profits, jobs)
