This summary provides an overview of the content you've shared. If you have any specific questions or if you'd like to discuss any of the points in more detail, please feel free to ask!It appears that you've provided information about a recent situation involving a hepatitis A warning for guests of Auberge Chez Jean in Montreal. The warning was issued by Montreal public health due to potential exposure to hepatitis A, a viral infection that affects the liver. Here's a summary of the key points from the information you provided:

Exposure Period: The potential exposure to hepatitis A occurred between July 29 and August 18. This period coincided with events like the Osheaga music festival and Montreal Pride week.

Vaccination Recommendation: Anyone who stayed at Auberge Chez Jean during the mentioned period is advised to get vaccinated against hepatitis A if they haven't already been protected. Vaccination can help prevent the development of the infection.

Symptom Monitoring: People who stayed at the hostel during the exposure period should monitor their symptoms for 50 days after checking out. Symptoms of hepatitis A include feelings of malaise, nausea, abdominal discomfort, vomiting, loss of appetite, fever, jaundice (yellowing of the skin and eyes), darkened urine, and pale stools.

Serious Complications: While most people recover from hepatitis A within two months, certain groups such as the elderly, immunocompromised individuals, or those with liver disease can develop acute liver failure, which can be fatal. Some cases of liver failure may require a transplant.

Transmission: Hepatitis A is transmitted through the stool of an infected person. It can spread through contaminated water, food, drinks, and objects. Person-to-person transmission can occur, including through sexual intercourse. Asymptomatic individuals can still spread the virus. People with the virus are considered contagious for about two weeks before jaundice or illness onset and up to one week after.

Preventive Measures: To prevent transmission, it's important to thoroughly wash hands after using the bathroom, changing diapers, assisting a child with using the toilet, and before handling food. Contaminated surfaces, especially those used by children, should be cleaned properly.

Vaccination Location: Those in need of vaccination can receive a free hepatitis A vaccination shot at the Berri-Centre-Sud vaccination site.
