As the H1N1 or Swine flu rages across North America, with governments displaying an immense amount of inability to cope with a pandemic and stories of celebrities, hockey players and hospital boards getting their flu shots early, I thought I’d bring you an indepth summary of H1N1 symptoms.  Should you get the shot?  Perhaps, if they’ve got any left because they keep running out.  Some doctors think it’s a waste of time.   Whatever you do, remember to wash your hands often and best with an automatic soap dispenser which every home and public place should have.  If you feel flu symptoms, go to a doctor immediately to see if you actually have the H1N1 flu.This piece of health news comes from The Globe and Mail online newspaper.

People can become ill if the flu virus enters their nose, eyes or throat after an infected person coughs or sneezes. They can also become ill after touching an infected surface, such as a doorknob, keyboard or countertop, and then touching their mouth or nose.

The virus begins to grow, and symptoms can start to develop 24 to 48 hours after initial infection. However, it can take up to a week for symptoms to develop. People seem to become contagious one day before the onset of flu-like symptoms, says the Public Health Agency of Canada.

Doctors say most people can’t properly distinguish between a cold and the flu, but that influenza viruses come with several telltale symptoms. Similar to seasonal flu viruses, H1N1 symptoms include sore throat, cough, headache, loss of appetite, fatigue and aches and pains.

Fever, a typical symptom of seasonal flu, isn’t appearing in all H1N1 cases, said Earl Brown, a virologist at the University of Ottawa. But more people with H1N1 seem to be experiencing vomiting and diarrhea than they would with a regular seasonal flu virus, Dr. Brown said.

People with H1N1 will typically spend from two to four days in bed. But serious symptoms require medical attention, including shortness of breath and extreme lethargy or being “out of it,”

The average person with the H1N1 virus will be back on their feet after about a week. However, it could take from two to three weeks before they feel 100 per cent, Dr. Brown said. People who are infected with H1N1 may remain contagious slightly longer than those with seasonal flu.

Public Health says people infected with H1N1 remain contagious for about a week after they develop symptoms.  However, some people’s symptoms can grow worse after they initially begin to improve, which could be a signal of a secondary bacterial pneumonia. Although different from viral pneumonia, one of the rare and serious complications appearing in a small number of people with H1N1, bacterial pneumonia is very serious and requires medical intervention.

Coughing up blood or turning blue are obvious danger signs. But another key warning sign is shortness of breath. Parents whose children are ill should monitor them to see whether they are breathing rapidly. “I sure as hell wouldn’t be waiting around at home to see how I do once I’m short of breath,” Dr. Kumar said. “It can be very rapid once it goes to your lungs.”

This virus, much more so than seasonal influenza virus, tends to attach to the cells within the lower respiratory tract where it can cause severe infection, experts say. This infection of the lungs can trigger a cascade of inflammatory responses. Once the virus attaches itself to the deep respiratory cells, it starts to damage the lungs, which start to fill with fluid, and the person can’t get enough oxygen. There is evidence the virus can go to the heart in rare circumstances, which can lead to rhythm disturbances and death.

It looks like it will be necessary to get that flu shot after all with the latest information in the health news reports.  Even though the press is not talking as much about the subject, there are still warnings and precautions about the Swine flu – H1N1 virus given out by the World Health Organization.  There has been a rise in the number of people who have been struck by the flu virus and an increasing number of deaths world wide.  For more information, please read further this article at the CBC News health site.

“The global swine flu epidemic is still in its early stages, even though reports of over 100,000 infections in England alone last week are plausible, the World Health Organization’s flu chief said Friday.

Keiji Fukuda, WHO’s assistant director-general for health security and environment, told The Associated Press that given the size of the world’s population, the new H1N1 virus is likely to spread for some time.

WHO earlier estimated that as many as two billion people could become infected over the next two years.

“Even if we have hundreds of thousands of cases or a few millions of cases …we’re relatively early in the pandemic,” Fukuda said in an interview at WHO’s headquarters in Geneva.

The global health agency stopped asking governments to report new cases last week, saying the effort was too great now that the disease has become so widespread in some countries.
Authorities in Britain say there were over 100,000 infections in England alone last week, while U.S. health officials estimate the United States has passed the one million case mark. Those figures dwarf WHO’s tally of 130,000 confirmed cases worldwide since the start of the outbreak last spring.

“We know that the total number of laboratory confirmed cases is really only a subset of the total number of cases,” Fukuda said.
Fukuda, the former chief of epidemiology at the U.S. Centers for Disease Control and Prevention, also said there must be no doubt over the safety of swine flu vaccines before they are given to the public.

Dramatic rise in H1N1 cases expected

Health officials and drug makers are looking into ways of speeding up the production of the vaccine before the Northern Hemisphere enters its flu season in the fall.
The first vaccines are expected in September and October, said Fukuda. Other vaccines will take until December or January before they are released onto the market — well into…”

With the latest health news reports on the H1N1 which says that H1N1 is Tamiflu-resistant, people are somewhat worried especially with the flu season just months away.  However, Reuters reports that this is a single case and we do not have to worry too much.  The pandemic alert is still high though which means that you should still be planning to get your flu shot this year when flu season begins.

“The first H1N1 infection found to be resistant to the antiviral drug Tamiflu represents an isolated case with no current implications for public health, the World Health Organization (WHO) said on Tuesday.

“The United Nations agency has declared a global pandemic is underway from the virus known as swine flu which has so far been treatable with Tamiflu, made by Roche.

WHO spokesman Dick Thompson said that the discovery of a patient in Denmark whose infection did not respond to the drug, revealed by the Swiss company and Danish officials on Monday, did not amplify the severity of the virus.

“This is an isolated case. At this time, there is no public health implication. But we must remain alert as the virus can change at any time and we must not be complacent,” he told Reuters.

Officials say the patient is now well and no further contagion with the resistant virus was detected.

Resistance to Tamiflu has been previously documented in the deadly bird flu virus H5N1 and seasonal H1N1 flu, Thompson said.
“We need to monitor the virus (H1N1) continuously,” he said, adding that the WHO’s global influenza surveillance network linking laboratories in 97 countries would keep monitoring it.
“WHO is not changing its recommendations for the use of antivirals,” Thompson added, referring to the global body’s advice to its 193 member states.

The WHO has previously said that the H1N1 virus is sensitive to a class of antiviral drugs which includes Tamiflu, known generically as oseltamivir, and Relenza by GlaxoSmithKline, known generically as zanamivir.

Denmark’s State Serum Institute said, when making the announcement on Monday, that it was expected that the strain would at some point show resistance to Tamiflu.
It said that while the patient was found to be infected with a virus strain that had mutated to a form resistant to Tamiflu, the alternative drug Relenza, which is inhaled, remained an effective treatment.

GLOBAL PANDEMIC

The WHO on June 11 raised its pandemic flu alert to its highest level of 6, signifying that the first influenza pandemic since 1968 was under way [ID:nLC321991]
Flu viruses mutate regularly and can develop resistance to drugs at any time.”

Remember, young and old alike are affected by the H1N1 virus, which means that you must not forget to get your flu shot.
