The H3N2 flu<\/a> strain is landing more people in the hospital in the United States, and experts are urging Canadians to exercise caution amid a \u201cperfect environment\u201d for spread and a fresh round of case numbers expected in this country next week.<\/p>\n

\u201cSome parts of the United States are reporting the highest rates of flu hospitalizations since they\u2019ve kept records,\u201d said Dr. Fahad Razak, internal medicine physician at St. Michael\u2019s Hospital and professor at the University of Toronto.<\/p>\n

In the week ending Dec. 20, one in four (25.6 per cent) cases of every influenza test conducted in the U.S. came back positive, the CDC said.<\/p>\n

This was a sharp increase from 15.7 per cent of tests coming back positive in the week ending Dec. 13 and nine per cent for the week ending Dec. 6.<\/p>\n

For the week ending Dec. 20, 19,053 people were admitted to hospital in the U.S. with the flu. Five children died in the U.S. in the week ending Dec. 20 after an association with influenza, the CDC added.<\/p>\n

\u201cWe can look to other countries, the experience in parts of Europe, now the United States and before that in Australia and Japan suggested some of the worst, or the worst, flu seasons on record,\u201d he added.<\/p>\n

Razak said the \u201cenormous amount of human flow between the two countries, especially over the holidays,\u201d should give Canadians pause.<\/p>\n

\u201cThat is a perfect environment for an infectious disease to spread,\u201d he said as Canadians and Americans return from seeing family on both sides of the border over the holiday season.<\/p>\n

\u201cIf you think about our border with the United States, it\u2019s the kind of border where when you have a high rate of illness that\u2019s transmissible on one side, it\u2019s nearly impossible to keep it out from the other side,\u201d he added.<\/p>\n

The rate of hospitalization from influenza in Canada has nearly doubled compared to the previous week of available data, with infections now up almost 30 per cent, Health Canada\u2019s latest figures show.<\/p>\n

For the week ending Dec. 13, Canada saw 11,646 new cases of flu being detected, which means 27.7 per cent of all the tests conducted in the country came out positive.<\/p>\n

Health Canada\u2019s next flu update, which will include data from the period covering Christmas Day, will be released next week.<\/p>\n

\u201cMore people in general are getting sick, so the volume of infections is higher. And when you have more people infected, there\u2019s more people who can get critically unwell and end up in hospital,\u201d he added.<\/p>\n

As children get ready to head back to school on Monday after the holiday season, Razak said there is still time to get yourself and your family vaccinated.<\/p>\n
