Hepatitis C Support Group
Hepatitis C is a blood-borne viral disease which can cause liver inflammation, fibrosis, cirrhosis and liver cancer. The hepatitis C virus (HCV) is spread by blood-to-blood contact with an infected person's blood. Many people with HCV infection have no symptoms and are unaware of the need to seek treatment. Hepatitis C infects an estimated 150-200 million people worldwide.
More than 100 people have been hospitalized, and most of the cases are caused by the H1N1 strain.

"The study found that people 85 years and older have the highest rates of seasonal influenza-associated hospitalization."
"The study concluded that, on average, more than 200,000 people in the United States are hospitalized each year for respiratory and heart conditions illnesses associated with seasonal influenza virus infections".
"The U.S. population is growing older and therefore, more vulnerable to developing severe complications from seasonal influenza."

Overall Summary
Influenza activity in Canada continued to increase sharply in weeks 51 and 52 with increases in laboratory detections of influenza, ILI consultations, hospitalizations with influenza and prescriptions for influenza antivirals.
Influenza A has been identified in >90% of cases this season, and A(H1N1)pdm09 remains the predominant subtype, representing approximately 90% of subtyped influenza viruses.
A greater proportion of cases have been reported among adults 20-64 years of age compared to those 65 years of age, which is a change from the demographics of the 2012-13 season when A(H3N2) was predominant.
FluWatch is Canada's national surveillance system that monitors the spread of flu and flu-like illnesses on an on-going basis. FluWatch reports, posted every Friday, contain specific information for health professionals on flu viruses circulating in Canada.
The FluWatch program consists of a network of labs, hospitals, doctor's offices and provincial and territorial ministries of health. Program objectives include to:
Detect flu outbreaks across the country as early as possible
Provide timely up-to-date information on flu activity in Canada and abroad to health professionals [and interested Canadians]
Monitor circulating strains of the flu virus (like H1N1) and assess their sensitivity to antiviral medications, [such as Tamiflu and Relenza]. Antivirals, when used by doctors to treat flu, can help reduce the severity of the illness and the recovery time for a patient
Provide information that the World Health Organization can use to make its recommendations on the best vaccine to use for seasonal flu shots.

Differences between the H9N2, H5N1, H10N8 and H7N9 bird flu strains:
Sources of human infection
H9N2 chickens, ducks, magpies, sparrows, waterfowl
H5N1 first spread from poultry in Hong Kong in 1997
H10N8 detected in water birds on mainland in 2007
H7N9 detected in mainland live chickens and wet markets since first human infections in March
Possibility of human-to-human transmission
H9N2 no evidence yet
H5N1 appears low
H10N8 believed to be low, as most of its genes come from birds
H7N9 limited; only suspected to have been transmitted among people in four patient clusters
Number of cases
H9N2 11 in southern China since 1998
H5N1 at least 22 in Hong Kong since 1997; 648 cases globally since December 2003
H10N8 one (on the mainland)
H7N9 143 since February, all in China
