Have you ever been tested when you have a severe viral bug?

Another couple of trips around the frog pond. I haven't left the property since getting this virus. One of our contractors had it twice, he said. I am seriously wondering if it is something like the Enterovirus D68, or Influenza A or B. The Whooping Cough type of cough I have had is horrible.
It's been 3 weeks. I've gone from diarrhea, to a head cold, to a cough. Then, sinusitis, bronchitis, pneumonia, on antibiotics, still some sinusitis, and a cough.

This is pretty scary stuff: from White Coat Black Art:
More than a hundred children in the US -- and at least six in Canada -- have developed a mysterious form of paralysis. Health officials are trying to determine if it could be related to Enterovirus D68 which has hospitalized hundreds of kids in North America.
CBC.CA


None of our healthcare people suggested a test. It isn't mandatory that the provinces and territories report these flu incidents. Yet, it does kill. Many long-term care homes are shut down. It is so easily spread. Some kids are getting some paralysis with the Enterovirus. I believe it is under-reported.

Lots get awfully sick with flu each year.
This was last moths chart.
Have you ever been tested when you have a severe viral bug? Normally, you stay at home, although many do not or cannot.

The Media is focusing on Ebola, rather that the flu bugs, which are killing the very young and old:

Alberta Week 42 of 2014:




  • 3 deaths
  • 30 Albertans have been admitted to hospital
  • 66 laboratory confirmed cases of influenza A so far
  • 8 laboratory confirmed cases of influenza B


  • This year's more virulent Enterovirus seems on the wane

    Toronto Star-Oct 19, 2014Share
    By: Joseph Hall News reporter, Published on Sun Oct 19 2014 ...Ontario has had more than 160 confirmed cases. It has been linked to seven deaths in the U.S. ... yet far less ballyhooed viral threat — the annual influenza that kills tens of thousands across the continent each year — is in the offing.

    Back to the frog pond

    I love the frog pond, although perhaps we should now call it the muskrat pond. I've carved out a path and walk right around it. It's a bit of exercise for me, some fresh air, and the cats have a grand time.
    You can tell the muskrats by their rat-tails! They are very furry.

    This time, Dorah came along and decided to climb a tree- she went very high in the penultimate photo.
    There was ice on the pond (3rd from the last photo). Winter is coming!
    I've counted 4 muskrat structures, so far. Talk about 'busy as a beaver.' I saw two of them the other day, They took off as soon as we arrived at the pond. That day it was Buster with me.

    Canadian H1N1 Statistics: confirmed cases, hospitalisations, deaths

    I've been following the statistics.
    Week 2 are the most recent. FluWatch keeps stats weekly.
    They say the worst of it has passed.
    • To date this season, 2,298 influenza-associated hospitalizations and 113 deaths have been reported by participating provinces and territories.

    According to the Canadian Medical Association Journal (Jan. 14/14):

    DOI:10.1503/cmaj.109-4701

    The worrisome factor at this point "is the reported mortality rate in Alberta," says Dr. Pierre Lebel, an infectious disease specialist at the McGill University Health Centre in Montréal, Que. As of Jan. 13, there were 10 confirmed deaths in Alberta attributed to type A (H1N1) influenza, as well as 1 in British Columbia, 6 in Saskatchewan, 6 in Ontario, 1 in Quebec and 2 in Nova Scotia.

    The CMA tells us that while H1N1 has shown up in Canada again, it's no where near what it was in 2009. Normally, seasonal flu will strike 20,000 who must go into hospital. Normally, between 4,000 and 8,000 people die each year from flu. So far, this season,
    "Since the start of the 2013-14 season to January 4, 2014, 33 deaths have been reported from participating provinces and territories: three cases under 20 years of age and thirty cases 20 years of age or older."
    It's really difficult to find up-to-date info, with FluWatch.ca being at least a week behind.
    The reports of deaths (text vs. graph) from influenza are contradicted on its site:
    Graphs of flu deaths over time

    Total deaths 317?

    After killing 248,000 people worldwide in 2009, this year (2013/14) Europe is seeing H3N2 as predominant. There are many mysteries around influenza.

    It's very interesting to see how the number of cases doesn't match for population sizes. Ontario, with a population of 12.8m has about 2600 confirmed flu cases; Alberta, with only 1/3 the population, has nearly as many cases: 2340.

    Week 2
    FLU 2014 TYPE A A + B
    Provinces            Cases
    Population
    Ontario 2590 2646        12.8m
    Alberta 2332 2357      3.6m
    Quebec 1410 1669
    B.C. 887 908      4.6m
    Saskatchewan 725 726      1m
    Manitoba 120 129     
    Newfoundland 82 108 
    N.B. 235 236   0.75m
    N.S. 30 30   0.9m
    PEI 1 1  
    Canada 8412 8810        35m

    Here is week 1 (Dec. 29 -  Jan.4).
    It's move into the Outawois, southern Quebec.
    And widespread in Alberta.

    Hopefully, it will peak soon.
    You can see the differences between hospitalisation rates and deaths back when H1N1 first confronted us.

    We have learned lessons, and it appears that the vaccines have been working pretty well.

    Influenza H1N1 is bad this winter: 2013/2014

    Flu Watch webpage

    FluWatch web site
    H1N1 dose
    Hunkered down, with a freezing rain warning, a wind warning, and a flash freeze warning, it's seems to be a good day to stay home! The roads are terrible.

    I've been amusing myself with research. To see where the flu is active in Canada, visit FluWatch.

    FluWatch.ca produces weekly influenza surveillance reports from October to May, but they only report laboratory-confirmed test results. I'm sure you know people who have fought this virus and won. Most of the testing has shown that over 90% of flu results indicate that it is the H1N1 that is causing these illnesses.
    Canadian activity

    Unfortunately, it is really hard to find specific statistics by province. Flu Watch reports all of Canada. This site collects Yahoo news of H1N1 articles.

    You have to go to provincial or regional health centres, and/or local newspapers, for data broken down by province or territory and they report metropolitan area healthcare systems (i.e., the large cities). No one wants to brag about how many cases of flu they have!

    Ottawa Health has had two deaths from flu and 3 outbreaks in long-term care homes. There were 81 lab-confirmed cases, but there are many who do not report and do not test for the virus. There were 22 people placed in hospital.

    Toronto Health has had 210 confirmed cases, with 6 deaths. It's bad in Ontario, but the provi
    Red = H1N1 "A"; Blue = Type B flu
    nce of Alberta is the worst so far with 965 confirmed cases, 5 deaths.

    The Vancouver  Sun reports: "About half of Fraser Health's severe cases involve "significantly overweight" patients, who are more susceptible to more serious symptoms." There were 11 cases in long-term care (a high-risk population), 20 hospitalizations, and, perhaps, one death (yet to be confirmed).

    Flu Watch tells us that the very young and the very old were the most at-risk in the 2009 pandemic, but this year, 24 - 64 year olds have been more susceptible, and getting ill, as well as the very young.

    Our seniors have, it seems, developed antibodies, bless their souls. There is research to show that slight exposure does build up your immunities. "The things that don't quite kill you make you stronger."
    August - December 2013. They track confirmed cases only, I wonder how many unconfirmed there are?
    The territories report to particular labs in provinces.

    FLU 2013 TYPE A A + B
    Provinces Cases Flu-related Deaths Population
    Ontario 1006 1033      8 12.8m
    Alberta 868 1335      9 3.6m
    QC 365 462
    B.C. 229 239      1 4.6m
    Saskatchewan 167 167      6 1m
    Manitoba 28 35

    N.S. 8 8 0.9m

    The cities are the worst, with people who commute.

    Week 52, Geographic spread of influenza
    In week 50 (December) four regions had local, sporadic activity. Methinks the holiday season spread the virus aplenty ( Figure 1 )! By week 52 you can see how they increased.

    I cannot find specific data for NWT. I tried!
    Alberta

    Ontario reports: SE Ontario is bad.
    Alberta is worse.
    Alberta’s H1N1 outbreak leads to rush in flu vaccinations ...
    There have been 965 lab-confirmed cases of influenza in Alberta as of Jan. 1, with the H1N1strain representing 920 of those cases. There are  270 in hospital in Alberta. With 3 dead in Edmonton, 2 and dead in Calgary.
    I'm amazed at the number of people who still eschew the vaccine. We hunker down in groups for winter: in schools and offices, with people who come to work quite ill. How can you NOT be exposed to the virus?! There are many who still don't cough or sneeze into their elbows. It boils down to washing your hands. There is little else to do, really. Stay home if you are ill. Get enough sleep, eat properly, exercise, and go outside to play! I find there are many personal support workers (PSW) doing home care who do not wash their hands frequently enough. I've seen them during my hospice work.

    Flu shots are freely available from your Canadian physician, or from health clinics, each province/territorial health authority makes them available.
