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).

Can you get swine flu in crowded places?

Yes, it is a highly contagious influenza virus and the best plan is to avoid crowded places if at all possible. Follow the precautions explained in the related questions below for how to avoid catching the virus, including frequent thorough hand washing, if you must be in public places where the Novel H1N1 virus is present.

The Centers for Disease Control and Prevention (CDC) have recommended that if you must go out in communities with known active cases of the Novel H1N1 flu avoid crowded places. If you are at high risk due to age or underlying medical conditions, you should also consider wearing a specially fitted virus filtering facemask (not just a surgical facemask) or respirator.

CDC defines at risk persons as:

"Persons at increased risk of severe illness from influenza (i.e. high-risk persons) include those groups at higher risk for severe illness from seasonal influenza, including: children younger than 5 years old; persons aged 65 years or older; children and adolescents (younger than 18 years) who are receiving long-term aspirin therapy and who might be at risk for experiencing Reye syndrome after influenza virus infection; pregnant women; adults and children who have pulmonary, including asthma, cardiovascular, hepatic, hematological, neurologic, neuromuscular, or metabolic disorders, such as diabetes; adults and children who have immunosuppression (including immunosuppression caused by medications or by HIV); and, residents of nursing homes and other chronic-care facilities."

How do you prevent the further spread of a pandemic?

H1N1 can be prevented if you practise good personal hygiene. The virus can live for up to 48 hours. They live longer on non-porous surfaces like plastic, metal and wood and live shorter on porous surfaces like fabrics, skin and paper. Minimise the use of public things such as public phones etc. Maintain social distance and victims of H1N1 must stay at home and rest, avoid going to crowded places. Try not to practise the sharing of personal items like a toothbrush, food and drinks.

What is the prodomal stage of flu symptoms?

Typical flu symptoms will be overall body aches, fever, and sometimes vomiting. Usually the person will just feel miserable and want to rest and sleep. The flu can last from 24 hours to several days.

Why did the influenza epidemic of 1918 spread across several continents?

Instead of killing mostly infants and elderly, it had little effect on them and killed mostly young adults. A group rarely significantly affected by flu. It also caused significant neurological problems in some survivors, which is also rare for flu.

What is the name for the anti-viral medicine for swine flu?

The CDC recommends the use of oseltamivir (Tamiflu) or zanamivir (Relenza), both anti-viral medications for the treatment and/or prevention of infection by swine influenza viruses. These Antiviral drugs work by keeping flu viruses from reproducing in your body.

The best way to avoid the symptoms of the flu is to get vaccinated so you can't catch it in the first place. But if you do get the flu, then ask your doctor about these two of the anti-viral medications. They have proven safe and effective to speed the recovery and lessen the severity of symptoms. They have been underutilized in general by ordering physicians and could make you feel much better much faster.,

Is a cold virus an active virus or a hidden virus?

Active. It will go directly to find a host cell and begin the steps of the lytic cycle to cause the host's cell to replicate the virus (see the related questions for more about the lytic cycle). It does not stay "dormant" inside you to manifest symptoms later. An infection will produce symptoms right away if you are infected. Then, once new viruses are made in the host cell, they will burst out and infect more cells and potentially more people.

Are you contagious when you get the flu shot?

No. Live vaccines are produced with careful culturing methods that ensure the virus is no longer able to do much, if any, harm.

In addition, they're given in the arm, which is not where a virus spreads from, and is not the optimal location for the viruses, so your immune system can quickly get it.

What are the symotoms the the H1N1 virus?

Symptoms of H1N1 swine flu are like regular flu symptoms and include fever, cough, sore throat, runny nose, body aches, headache, chills, and fatigue. Many people with swine flu have had diarrhea and vomiting.

Which country is worse affected by swine flu?

All countries have been affected by the swine flu infections of their people. "Most" affected would have to be based on a definition of what is considered an affect and how to measure the affect. By percentages, the count of cases and deaths is relatively equal among countries, although perhaps North American countries have had the most affect.

There may be some ongoing cases in limited locations around the world, however, even now. 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, preventive vaccines are available, and people are educated on prevention. 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.

Can you try for a baby when Swine Flu is going around?

Yes, and if you are taking oral contraceptives and the doctor gives you an anti-biotic it can kill not only the bug, but the effectiveness of your pill.

Why do you get a new flu shot every year?

Viruses mutate very quickly. As they move through a population, passing from individual to individual, they change to bypass the immune system defenses and environmental conditions and sometimes they just make random changes from imperfect replications. Many viruses will be almost completely genetically different from their parent or grandparent viruses.

The flu shot we get each year has been developed to contain the three types of currently active flu viruses determined by epidemiologists to be most likely spreading in the next flu season. These are rarely the same viruses year to year because the prior year's viruses have almost always mutated to new forms before they circle around again the following year.

When you get a flu shot, your body reacts and produces antibodies in the blood that fight off those particular flu viruses for life (in some circumstances, but in others the immunity does lessen over time). The problem is that each flu season brings a slightly (or greatly) changed flu virus that the last year's antibodies are usually not very effective in fighting.

More:

The flu vaccine is made based on what scientists think will be the next year's most active flu viruses. If they waited until the first flu cases, there would not be time to produce all the vaccine needed for millions of people. They study what viruses are circulating in other parts of the world to determine scientifically which are the most likely ones to hit during our next flu season. They make a pretty good forecast analysis.

This is also the reason that there is no cure for the common cold: there are 300-some different types of common cold viruses, and each of those can make slight changes (mutations) that make them unable to be recognized as the same by your immune system. Once you have had one of those, you may not ever catch that exact same cold virus again, but the changes and mutations occur often and quickly in the cold viruses, so it is close to impossible for your body to make new antibodies to defend itself against the newest versions or for your previously made antibodies to be close enough to work on the mutated viruses.

What is worse Swine Flu or bird flu?

To date the Spanish flu of 1918 has been the worst flu pandemic on record killing millions of people. The present Bid flu (H5N1), which has only killed a few hundred people, remains only a threat as it still cannot be transmitted from human to human a requirement for it to become a pandemic.

What are the symptoms of swine fli?

The first simptoms are runny nose and high temprature

Where can you get a flu jab?

Usually they have a cost. But sumtimes clinics offer them for free.

Answer:

It depends where you live. Countries with national health care plans provide free vaccinations against a wide range of illnesses including annual and special flu shots.

What is the most effective way in determining whether someone has been infected with the H1N1 influenza virus?

Usually tests aren't required to diagnose the H1N1/09 influenza, doctors go on the symptoms and history of potential exposure, as well as whether there is a big presence of the disease in the community at the time.

But there are tests for it. One that is more easily done in the field is a rapid test that, although easy to do and convenient, is less accurate than tests performed in the laboratory. See the related link to the CDC for information about the different tests.

When swine flu is suspected in a patient, a quick test is typically done to determine whether Type A or type B influenza is present. If the test results reveal that the patient has type A influenza, they could be infected with either a conventional flu strain or swine flu. Swine flu is diagnosed by evaluating the patient's symptoms and knowing if the person has been in contact with people known to have the condition. A definitive swine flu diagnosis is made by sending a sample to a specialized lab.

Can person develop hives after receiving the swine flue vaccine?

Hive is a form of allergic reaction, period. What this mean is that anything you are allergic to can be result in hives. So, if you just happened be allergic the the swine flu or any of the ingredients within it, then the hives you have may be the result of the vaccine. It can also be something you're exposed to at around the same time as when you got the vaccine, like new food, soap, detergents, deodorants, ect.

Is it okay to take medication after getting a regular flu shot?

If you are over 18. The NSAID (non-steroidal anti-inflammatory drug) Aspirin (ASA, acetylsalicylic acid) can be used as an antipyretic - which means, it will help to reduce fever. Fever reducers are good to use if the fever is high, e.g., 102 F (38.89 C) or over . It is better for many people to avoid fever reducers with the lower fevers since one way for your body to fight off these viruses is to raise and keep your body temperature up over the normal temperature of 98.6 F (37 C).

For the higher grade fevers, you could use aspirin if you are otherwise able to take aspirin (see below). You could also use naproxen, ibuprofen or acetaminophen for high fevers. They are all NSAIDS and can help you feel better from aches and pains, reduce inflammation such as swollen sinuses, etc. and treat fever.

But those under age 18 should not take aspirin when they may have a virus or flu since there is a risk of Reye's Syndrome with that medication use with some viruses.

Do not mix more than one type of NSAID at a time. For example, whatever you take for fever will also provide pain relief and vice versa.

Whether you should use aspirin can also depend on what other drugs you may be taking.

Ask your pharmacist for recommendations for what analgesics, anti-inflammatory and/or fever reducer medicines would be best for you.

What infectious agent is involved in Swine Flu?

"Swine flu" is a viral infection of swine (pigs). There is evidence that this virus is the same that infected humans in the 1918 pandemic. It has been labeled the N1H1. There has been controversy that the flu now is a variant of this 1918 flu. We are not sure where it started: pigs or humans?

"Swine flu" H1N1 virus produces similar influenza-like illnesses. Symptoms include fever, cough, sore throat, body aches, headache, chills and fatigue and some diarrhea and vomiting. The present H1N1 virus is not zoonotic swine flu, as it is not transmitted from pigs to humans, but from person to person.

When was the most recent flu pandemic and how many people did it kill?

It was the Spanish flu pandemic of 1918-1920, and it is estimated to have been responsible for approximately 80 million deaths world wide.

How did the whole swine flu thing start?

The swine flu H1N1 strain actually started in pigs, hence the name "swine flu". The first Swine flu viruses were isolated in 1930 in the United States in pigs.

It mutated to be able to cross species just like the Influenza type A, H5N1 Avian (bird) flu, but that one came from birds. Flu viruses mutate very quickly, and when they do, they can sometimes form a type of virus that can be transferred from one species to another when there is regular contact between the species in crowded conditions. It is not that common but because pigs are physiologica lly very similar to humans it makes it easier for the virus to use them in the "reassortant" (the process that combines different species' genetic material within a virus). This is what happened with the swine flu - it jumped from pigs to humans after a mutation of the virus. There have been several outbreaks of swine flu of this type among humans over the years, the most well known occurred in 1976, but it was not a widespread occurrence in most of those outbreaks.

The 2009 Swine Flu (Novel H1N1 Influenza type A) evolved similarly when the H1N1 virus strain that pigs get combined genetic material from pigs who had previously been infected by swine flu and bird flu with genetic material from a human flu virus that also ended up in the same pig (this process is called "triple reassortant"). When a person (probably a worker in a pig farm) came into close contact with the pigs who had spread that mutation of the swine-bird-human virus among the herd, the virus was picked up and the farm worker became ill from the virus. That strain of virus then became able to be passed from human to human starting with the farm worker and the epidemic began.

What is the size of the Influenza A virus subtype H2N2?

80 - 120 nanometers (.08 - .12 microns). This is why masks don't help anyone but everyone else. Masks didn't help agains the SARS virus which is 100 nano meters, meaning it's safe to say, it won't help against the swine flu either.

How many people in Samoa have died from swine flu?

Since the daily and weekly counts of cases and deaths from the swine flu, which were initially required by the CDC, WHO, and national health departments of most nations have stopped since the pandemic was declared over, there is no way to know how many now. One reason is there are still ongoing cases scattered around the world even as of fall 2012. Another reason is that it was a burden on the reporting entities to try to track and report the numbers. And a large portion of people who had swine flu had mild forms and did not go to the doctor. Their cases could not be counted. And, if no lab test were done to confirm the specific type of flu, there is no way to know for sure if each case should be included in the count or if it is another type of flu.

The treatment is the same as for other types of flu, so there is no real medical need for testing to determine what form of flu someone has in most cases. For this reason, there is no definite count possible on cases of this type of flu any more.
