Det mest kända och omtalade sjukdomsutbrottet av cryptosporidium är den som inträffade i Milwaukee år 2003 då ca 400 000 personer insjuknade.[1]Cryptosporidium-utbrottet i Östersund vid årsskiftet 2010/11 har i sig klassificerats som Europas största utbrott av vattenburen smitta i modern tid. Dricksvatten är ett utav våra viktigaste livsmedel där vatten även är ett utav EU:s mest reglerade områden. Ändå har vattenrelaterade sjukdomsutbrott av den omfattning som den i Östersund kunnat ske. Detta ifrågasätter såväl den svenska, som den EU-rättsliga vattenrättsregleringen, dagens reningsteknik samt vattenproducenternas och myndigheternas kontroll och tillsynsansvar.

The coronavirus has recently turned our normal lives upside down in one way or another, not least our working life. Many employers had the opportunity to send their employees home so that they can continue their work in a safe home environment. Due to the nature of the work, other employers had to keep their employees in the workplace. The purpose of this study is therefore to examine the opportunities, options and responsibilities of the private employer so that these employees can still feel safe from infection even though they have to be at the workplace. This is done primarily by analyzing different sources of law. In addition, the aim is to examine, through a case study, the complex relationship between law and reality. It is mainly analyzed on the basis of a survey. Finally, the research aims to provide a final result that can help in future crises affecting the labour market. The study concluded that employers need to devote a lot of resources to their systematic work environment management, especially if they had short-time work allowance because it was found to cause mental and physical problems, mainly in the form of stress. Finally, it should also be noted how the rules on short-time work allowance should be more industry-friendly in the future.
