Swine Flu (H1N1/09)

The 2009 Pandemic Swine Flu, A-H1N1/09, the Type A influenza virus that was first identified in the early spring of 2009 in Mexico and then spread world wide to become a true Pandemic by June 2009. Different from other current seasonal strains of H1N1, and also not the same Swine Flu from prior epidemics or outbreaks (like in 1976), it is known by many different names in different places and settings, such as: H1N1, Novel H1N1, A/California/7/2009 (H1N1)v-like virus, la grippe porcine, The Mexican Flu, la epidemia, Schweinegrippe, and SOIV (Swine Origin Influenza Virus).

How many swine flu cases are in Florida?

There may be some ongoing cases in limited locations around the world, including in California. However, the specifics and counts of cases are no longer being tracked by CDC, WHO, the US states, and most other countries, now that the pandemic has been declared over. Influenza cases are monitored, but specific H1N1/09 counts (and the lab tests needed to isolate the specific virus to be able to count them correctly) aren't being done. Influenza cases in general are monitored, but statistics are not being kept for H1N1/09 cases separately from other influenza types for reporting any longer in the post pandemic phase.

As of November 22, 2009, there have been 4047cases* of Novel H1N1 Swine Flu in California, with 318 deaths.

*Statistics on laboratory confirmed case counts are no longer being reported or kept by the CDC since the cases were grossly under counted due to testing being done in fewer cases as the pandemic spread. The CDC has created a new methodology for estimated numbers of cases.

Does the H1N1 vaccine provide lifetime immunity?

How long is the vaccine in your body?
The H1N1/09 vaccine is very quickly absorbed by your body and then it is up to your immune system to take it from there to develop a resistance to the particular strain of flu virus that was in the vaccination and your body will develop the antibodies to protect against future invasions of the same virus. The vaccine was only there long enough to trigger your immune system to begin to work on the immune process.
How long does immunity from a vaccine or having the flu last?
If you are asking, "How long will I remain protected against H1N1/09 from a vaccination or from getting sick with the flu?", then the answer to this is a little more difficult to give.

You will be protected for life against that exactstrain of the H1N1/09 virus that was contained in the vaccine or that you caught which caused you to be ill, and you will likely also have some cross-over protection from very similar strains.

However, viruses do mutate easily, and if later you are infected with another strain or mutation of the H1N1 virus, and if your immune system does not recognize it any longer because it has mutated to a different form, then you may have no immunity to that new strain. This is one reason we need to take annual vaccines for the rapidly mutating common seasonal flu strains.

See the related links section below for a link to an article on the Time/CNN Health and Science web site about this subject. Here is an excerpt from that article:

It turns out, however, that those antibodies [developed from a flu vaccine or from having the flu] - unlike those against illnesses like tetanus or whooping cough - can provide a formidable and life-long defense against the flu, as long as they're pitted against the correct strain. For an explanation, TIME asks Eric Altschuler, assistant professor of physical medicine and rehabilitation at the University of Medicine and Dentistry of New Jersey, and co-author of a recent paper in Nature about antibodies to the 1918 pandemic flu virus.

Q: How long do flu antibodies last?

A: According to our study, it appears they can last the entire lifespan of the human organism - 90 years plus...

It's important to keep a record of vaccinations so the doctor knows when your child is due for a booster. Also make sure your child gets the seasonal flu vaccine each year. Having been immunized last year probably won't protect someone from getting the flu this year because flu viruses constantly change. That's why the vaccine is updated each year to include the most current common strains of the virus.

The flu vaccine reduces the average person's chances of catching the flu by up to 80% during the season. But because the flu vaccine doesn't prevent infection by all of the viruses that can cause flu-like symptoms, getting the vaccine isn't a guarantee that someone won't get sick during the flu season.

How did the Swine Flu spread to the US?

Yes, during the 2009 swine flu (H1N1/09) pandemic, there were effects in all of both North and South America along with all countries and continents of the world. Negative effects included illness, lost work production, lost wages, closed schools and universities, medical costs, and of course, deaths. With rapid production of an excellently matched vaccine, however, the pandemic has been declared over as the case numbers have dropped with more and more preventive measures in use. Only isolated outbreaks are currently ongoing in the world as of January 2012. Positive effects included the opportunity to test and evaluate measures that were in place to handle this type of infectious disease emergency to improve the plans. People were educated about preventing the spread of infectious diseases. World nations cooperated in the process to produce vaccines which helped create common ground for better international relations.

What is a vaccine that makes people immune to diseases?

In the simplest terms posiible you need to know that vaccines work WITH your immune system by building up your body's ability to DEFLECT unwanted diseases from your body. The vaccines are used to build up your resistance to the known pathogens. For instance a "flu" shot consists of pathogens of the influenzas the Center for Disease Control (and the World Health Organization) predict will be in season and should be included in the "flu shot".

Is it safe to take Tamiflu and penicillin at the same time?

The literature from the manufacturer of Tamiflu (oseltamivir) does not list that as a potential drug interaction problem. However, you should always notify your prescribing doctor if you are taking other medicines before you take any new prescriptions or use over the counter medicines with them.

The Tamiflu literature does state:


Information derived from pharmacology and pharmacokinetic studies of oseltamivir suggests that clinically significant drug interactions are unlikely.

No pharmacokinetic interactions have been observed when coadministering oseltamivir with amoxicillin, acetaminophen, cimetidine or with antacids (magnesium and aluminum hydroxides and calcium carbonates).

You got a flu shot over 2 weeks ago and your arm is still sore?

It sounds like the muscle is irritated. Typically, ice or a cool cloth used immediately after the flu shot can reduce any soreness. However, when it is more than 48 to 72 hours after the injection, you will need to switch to moist heat. You can use a washcloth soaked in hot water-- keep it folded, wet it, wring out the excess water, and lay it on the site for 10-15 minutes. Remove if too hot and try again in a minute or two. OR you can put a heating pad on low heat and put it on the site for 10-15 minutes. You can repeat either method every 4 to 6 hours as needed. If the heat does not help, or you have a lump under the skin or any hard area under the arm, see your doctor.

Can you have the flu and not know it?

Yes, for one or two days prior to feeling the symptoms of the flu, you can already be contagious. This is one of the reasons to be especially careful of close contact with others when the flu is known to be in your area, not only to protect yourself, but also to protect others.

Is the flu curable?

No, but it can be treated. There is no cure for the flu, our bodies must handle the infection using the immune system's defenses to render the virus inactive, instead. In the meantime, we feel the symptoms of the flu until the immune system has accomplished this. The symptoms can be treated and the duration of the viral infection can be shortened, however. For information about his, see the related questions below.

In addition, there are effective preventative vaccines for all well-known strains of flu, and the very few anti-viral meds on the market (like Tamiflu) seem to minimize symptoms and discomfort and can shorten the duration of the illness, but they must be given immediately upon manifestations of symptoms (within the first 48 hours) or they don't work as well.

How many died during H1N1 pandemic?

http://m.usatoday.com/health/700394/full/ The first analysis of children who have died of the new H1N1 flu virus shows that two-thirds had severe existing medical conditions, nearly half also got bacterial infections and a dozen were never treated with Tamiflu, the government reported Thursday. INTERACTIVE: Track swine flu across U.S., worldNOVARTIS: H1N1 vaccine may work on fewer doses Q&A: H1N1 and seasonal flu: Multiple doses, many questions At least 477 people, 40 of whom were children, have died of H1N1 influenza, also called swine flu, since it emerged in the United States in April. An analysis of 36 of the children's deaths found that 81% were age 5 or older, and 67% had high-risk medical conditions, including epilepsy, cerebral palsy, muscular dystrophy and other neuro-developmental disorders, the U.S. Centers for Disease Control and Prevention reported. In a typical flu season, half or more of children who die are 4 years old or younger. And about a third of children who die suffer from neurological disorders. CDC Director Thomas Frieden said Thursday that the study highlights the importance of treating children with special needs and neurological disorders promptly with antiviral drugs if they develop flu symptoms. It's also critical, he said, that "they're at the front of the line for flu vaccination when it becomes available." The first doses of flu vaccine are still expected to be ready for distribution by mid-October, Frieden said. At least 12 of the children who died between April and August never received the best available flu treatment, oseltamivir, sold as Tamiflu, the study found. In another five cases, CDC officials couldn't determine whether the children got Tamiflu. Other children weren't given Tamiflu until long after they became ill. A 1-year-old African-American boy, for instance, didn't get Tamiflu for 23 days after his symptoms began, CDC reported. Lena Napolitano, an intensive care specialist at the University of Michigan who has treated more than a dozen severely ill swine flu patients, says the analysis suggests that many physicians didn't suspect H1N1 virus caused the children's illness, adding that doctors shouldn't wait until test results come in before starting treatment. Ten of 23 children for whom test results were available developed bacterial infections on top of their viral infections, a double blow that can lead to toxic shock and death, CDC reported. Frieden noted that the pandemic, which simmered all summer, is heating up again, especially in the Southeast, where many schools began early. Flu has already forced school closures in two states. Twenty-three schools have closed in Tennessee and another in Indiana, affecting a total of 13,299 students, Justin Hamilton of the Department of Education said Thursday. Nineteen of the schools are in Blount County, Tenn., south of Knoxville.

Should someone 80 years old get the H1N1 shot?

The latest information is that, if your doctor agrees, you might as well take it if it is available to you, it won't hurt and might help. However, the incidence of the swine flu H1N1/09 is low among the demographic group of those 65 or older. It is not completely understood why, but it is thought perhaps there was a strain of flu they were exposed to in their past. that was very close to this strain of flu, so they have some cross-over immunity. It can also protect you from minor variant strains that may end up being very similar to the vaccine strain so you could get the cross-over benefit in the future. Reactions and side effects are as low as those with seasonal flu shots. (My 92 year old mother's doctor approved it, so she had one, and had no ill effects at all.)

How many cases of Swine Flu have there been in Michigan?

There may be some ongoing cases in limited locations around the world, including in Maine. However, the specifics and counts of cases are no longer being tracked by CDC, WHO, the US states, and most other countries, now that the pandemic has been declared over. Influenza cases are monitored, but specific H1N1/09 counts (and the lab tests needed to isolate the specific virus to be able to count them correctly) aren't being done. Influenza cases in general are monitored, but statistics are not being kept for H1N1/09 cases separately from other influenza types for reporting any longer in the post pandemic phase.

Is the Swine Flu in grants pass OR?

well, the swine flu is in the United States, but i don't think that the swine flu is in Oregon, but that's just me. you should go to www.webmd.com and type in swine flu and find out where it is. :)

How many people in the US have been infected with the Swine Flu?

Every state in the US has experienced the pandemic with many cases of swine flu (A-H1N1/09) in each state over the course of the 2009 pandemic.

There may be some ongoing cases in limited locations around the world even now, including in the US.

How long does Ebola virus live out of the host?

An Ebola victim will notice symptoms such as headache, sore throat, or shortness of breath 8-10 days after being exposed to the virus. There is no exact timeframe for the duration of the virus, but the fatality rate is 60-65 percent.

What to do for an abscessed tooth?

Normally, a dentist would prescribe antibiotics before doing a dental procedure (root canal, dental extraction or gum treatment). The dentist can also drain the abscess for instant results, but this cannot be done all the time, depending on the severity of the infection.

How many people have died of Swine Flu in the US?

"Regular" Seasonal flu viruses average 36,000 deaths each year in the US, out of over 30 million cases with approximately 200,000 hospitalizations. This statistic from the Centers for Disease Control and Prevention (CDC) is not limited to the swine flu viruses, but it would be typical. The 2009 Swine Flu, however, is a new mutation, so the figures of death rate are not yet compiled. As of the press briefing on 5/7/09 from the CDC, the 2009 Swine Flu, there are 1,823 probable and confirmed cases in 44 states. 5% are requiring hospitalization. There have been two deaths. The rates of infection, hospitalization, and death are expected to follow the usual course and increase, somewhat due to the updates of the numbers from the backlog of tests for confirmation, but also because that is the way the flu viruses behave. At the present time, this strain of swine flu virus would appear to be no worse and no better than the seasonal strains of viruses typically spread.

If you had Swine Flu in 1969 do you need a vaccination this year?

Just like other types of flu, there are different mutations and subtypes. Even if you have antibodies against one, you can still suffer from an infection of another. The current swine flu outbreak is from a new subtype. Therefore, if you were actually to be exposed to this swine flu, you do have a chance of becoming sick again.

When can you return to school after Swine Flu?

Your GP would recommend you to go back to school after no new chicken pox have started appearing, no chicken pox fluid is left waiting to be burst and when all your chicken pox have started to scab over with, which is scientifically called crusting.

How is Swine Flu test done?

If you’ve had contact with someone with COVID-19 or live in a community experiencing an outbreak and develop a fever and other symptoms of the disease, the CDC recommends you call your healthcare provider. Tell them about your symptoms and potential exposure to the virus, and they’ll make a call on whether you should be tested.

More specific guidelines vary from state to state. NBC News has a handy guide here.

It’s especially crucial that you call your medical provider if you’re elderly or have a serious chronic medical condition. Also, if you or a loved one are very sick (e.g., experiencing symptoms like difficulty breathing, persistent chest pain or pressure, confusion, or bluish lips or face), seek medical attention immediately.

Why is hypertension serious?

Hypertension, also referred to as high blood pressure is a major cause of heart attack, stroke and kidney failure. A good way to imagine blood pressure is to think of a baloon. Baloons are filled with air, but if too much air is put into the baloon, it bursts from too much pressure.

The blood inside the arteries exert pressure against the walls of the arteries. Too much pressure can weaken the artery walls, causing a burst to occur. If the burst occurs in the brain, it destroys brain cells causing a stroke. If the burst occurs in the heart, it can cause a heart attack. The kidneys are organs that filters blood, too much pressure inside them can cause them to fail.

Does the Swine Flu make you vomit?

Yes, many people had that symptom along with the more typical flu symptoms with the H1N1/09 pandemic swine flu (e.g., cough, fever, headache and body aches, sneezing, and fatigue). See the related question below about the symptoms of this respiratory viral disease.

How does a doctor check for H1N1?

Doctors test for viruses by drawing blood and sending it to the lab. Lab techs are able to use specialized equipment which check for different viruses and illnesses based on the specific test being ran.
