Pregnant Women Are More Risky In Swine Flu

Some complications among pregnant women as the Swine Flu continue to spread across the country, and soon to the world, and that this high-risk group needs to take antivirals as soon as infection is suspected. Just like what happen to a pregnant woman in Texas who suffers and died of Swine Flu infection. Medical officials believe that pregnant women are at higher risk of complications of influenza, whether it’s the seasonal influenza or pandemics of the past.

The Centers for Disease Control and Prevention (CDC) investigates twenty cases of pregnant women with the swine flu, most of them experienced complications. Complications can include pneumonia, dehydration and premature birth. It is very important that doctors who are caring for pregnant women they suspect may have influenza, that they issue prompt treatment with antiviral medicines the Tamiflu and the Relenza. Doctors can be hesitant to take care of pregnant women with antiviral drugs and pregnant women may be disinclined to take them out of fear that they may pose a risk during pregnancy.

The benefits of using the antiviral drugs to treat influenza in a pregnant woman outweigh the theoretical concerns about the drugs strongly say by the medical experts who have looked into this situation. Of the three swine-flu related deaths in the United States, one involved a 33-year-old pregnant woman from Texas who had other health problems before she was infected with the virus.

From the undetermined source that only one out of three Americans would get Swine Flu vaccine. So, it means the vaccine manufacturers have no enough capability to do more drugs against the outbreak.
There are many people who become ill don’t seek medical attention and are never tested for this strain of flu especially if they only knew that they only have simple kind of flu.

In other news that weve read about the number of Swine Flu cases from hospital records doesnt match with the real numbers suspected because they declined to seek medical attention.

The report also suggested that the true number of largely unreported swine flu infections in Mexico, the outbreak’s epicenter, possibly had already reached 32,000 cases and approximately 1% of them are pregnant women too. The World Health Organization’s official tally for Mexico stood at 2,059 confirmed human infections, including 56 deaths.

The United States has now surpassed Mexico believed to be the source of the outbreak as the country most affected by the epidemic, according to WHO statistics. The agency reported that there are 6,497 confirmed cases of swine flu in 33 countries, with Canada, Spain and the United Kingdom having the most cases outside of the United States and Mexico.

In the meantime, back in Mexico, federal health officials said that the worst seemed to be over despite more deaths, toll rose to 58 deaths and 2,282 confirmed cases of swine flu a rise of two deaths and 223 more cases.

World Health Organization expert expressed support for the more selective use of antiviral medicines such as Tamiflu and Relenza against Swine Flu even though the pregnant women and the doctors of the pregnant women are declining the use of antiviral drugs. According to health officials that there are some European countries aggressively take antiviral drugs throughout their population to save themselves.

While countries like the United States and Mexico, they are trying to save their patients with underlying conditions and also the other groups at risk, such as pregnant women and be treated. Swiss drug maker Roche Holding AG offered a charitable work to donate some of their Tamiflu supplies to the WHO enough for nearly 6 million people.

In Dire Need of Swine Flu Vaccine

According to the World Health Organization, efforts for developing a swine flu vaccine has been ongoing since the first human case of the virus has been confirmed. Estimates place the initial doses of the vaccine will be administered in 5 to 6 months time.

While people diagnosed with H1N1 virus seems to be headed for recovery, there have been deaths recorded. Aside from that, receiving vaccines for this virus is important particularly the elderly and individuals with a weak immune system, since they are prone to complications such as pneumonia.

Likewise, the vaccine will serve as protection in case the condition persists particularly during the winter months which is the time when influenza is at its peak.

According to the World Health Organization (WHO), although they are still incomplete, current evidence shows that seasonal influenza vaccines will provide minimal or no protection against swine flu. Every year, a new batch of flu vaccine is developed and matched with strains that the WHO determines will most probably circulate in the winter months, which happens to be the peak season for influenza outbreaks.

Influenza virus comes in various strains which contains different proteins on their surfaces. The body’s immune system can only fight and destroy a virus if they are able to recognize these proteins. It is worth noting that antibodies that recognize one strain may not detect other strains.
Existing vaccines may only offer some protection against swine influenza if the proteins on its surface are identical to strains used to develop previous vaccines. According to the NIBSC, they are trying to determine if the swine flu virus, which is an H1N1 strain of type A influenza, as well as previous H1N1 vaccines match current vaccines.

The preparation of a vaccine commences after a virus develops as they provide the starting point for the production of the vaccine. As such, there is always a time delay while a vaccine is being developed. Preparation of a vaccine involves several steps so it would take several months before a vaccine becomes available.

According to WHO estimates, the virus needed for producing the vaccine will be accessible to vaccine manufacturers by the middle of May while the initial dose for a new vaccine would be ready within 5 to 6 months after that. Waiting time would be much longer if the growth of the vaccine proceeds rapidly.

Vaccination plays a crucial role in the prevention and reduction of the effects of serious conditions. Unfortunately, they are not entirely effective and could lose its effectiveness if the virus mutates.
Existing flu vaccines are valid for about one year and are 70% – 80% effective against transmission with strains of influenza virus that are identical to strains used in the production of vaccines.

The WHO believes that it is too early to tell how the A(H1N1) virus would change. It is closely monitoring any changes in the virus and this would help countries quickly react to any important changes that the virus may show.

Vaccines help the body combat certain diseases in case an individual becomes afflicted with the illness in the future. On the other hand, an antiviral drug is used on people who is already infected with a virus. Although they work in various ways, they generally work to prevent the virus from spreading to different cells in the body.

Swine flu vaccines are administered prior to exposure to a virus so they would be protected from that agent. Antivirals only work if administered within a certain period of time before or after they are exposed to the virus.

Vaccinations of Swine Flu

Vaccine against seasonal influenza strain H1N1 is not believed to protect us. Vaccines against the Swine Flu to cope with seasonal flu to minimize infection rates are typically developed, and yet annually it still kills around half a million of the worlds population. Today, they use an injection of “killed virus”, the worlds flu vaccines. Manufacturers are asked to produce a vaccine for H1N1, they are unlikely to be able to respond quickly enough if a global pandemic is declared.

About a billion doses of any one vaccine each year is the only they can produce, so that even if all the capacity was switched to fight a pandemic flu, as opposed to a seasonal flu. Few years ago, the supply of the vaccines they have produced were enough to epidemic but now is not enough for the total populations outbreak.

Deadlier wave of a new H1N1 strain they forecast will reappear this fall and they have to produce pandemic vaccines as early as now to prepare for a turn out as the vaccine may not be as effective will be sure to a big waste of resources with serious results, and there would also be a shortage of seasonal flu vaccine available. Only a few more weeks were needed for the World Health Organization (WHO) and Centers for Disease Control and Prevention) CDC to develop a “seed strain” of the pandemic virus on the first days May, but producers would then need four to six months before they could create large volumes of vaccine.

In other point of view, the WHO will attempt to make sure that a substantial amount is available and should a pandemic be declared and a vaccine produced, for the benefit of developing countries. Vaccine manufacturers and countries with standing orders, such as the U.S. and some European countries will be asked to share with developing countries from the moment the first batches are ready if an H1N1 vaccine is made.

2009-2010 flu seasons are ineffective against the new strain with the previous influenza vaccines for the north and south hemispheres. The WHO claims that two separate immunizations will be required for seasonal and swine flu, but no decision would be made on whether to begin producing a swine flu vaccine. The board will receive inputs from manufacturers (e.g. GlaxoSmithKline, Sanofi-Aventis, Novartis and Baxter International) regarding when they are able to finish manufacturing the seasonal shot and begin production of the swine flu vaccine, waiting from the WHO of their recommendations and “seed virus”, and some may be ready to proceed with production at that time.

There also antiviral drugs available for treatments of influenza, the virus is resistant to amantadine and rimantadine but sensitive to the oseltamivir and zanamivir. There remains concern that this strain may mutate develop resistance to oseltamivir in the future. For the treatment and prevention of the Swine Flu, the CDC recommended the use of Tamiflu (oseltamivir) and Relenza (zanamivir). Studies shows that the medication continues to maintain its effective that why the U.S. government had already extended the shelf life of federally stockpiled Tamiflu from their original five years to seven years.

Buying medications from online sources is not recommended by the WHO because they believed that half of the drugs they sold are counterfeited. Others are thinking if they grab up antiviral drugs for their safe even if they have no symptoms, the health officials warned them may eventually lead them to the Swine Flu virus developing drug resistance.

Swine Flu: Overview, Treatment, and Prevention

Swine flu is an illness that is affecting hundreds of individuals in the United States as well as worldwide. According to the CDC, the illness may take some more time. Since one is likely to become infected with the condition, they need to understand swine flu symptoms in order for them to obtain proper treatment or medicaion.

The Symptoms

The symptoms of H1N1 infection is similar to that of seasonal flu. Among the symptoms include cough, sore throat, running or stuffy nose, chills and fatigue, to name just a few. Several people infected with the virus have complained of diarrhea and vomiting. The high risk groups prone to H1N1 is not yet known at the moment but it is likely that they are similar to those suffering from seasonal influenza.

People at greater risk of serious side effects from seasonal flu include people more than 65 years old, children below 5 years old, pregnant women, and people with chronic medical consitions as well as those who are taking immunosuppressive medications or with HIV infection.

Avoid Social Contact

If you are feeling sick, your condition may last for more than a week. You should remain at home and refrain from making social contact. As much as possible, you should not communicate with other people to avoid the spread of the virus.

At the moment, the CDC believes that H1N1 has similar properties on the aspect of transmission with seasonal flu virus. If you go out of the house to consult your doctor, wear a mask or use a tissue when coughing or sneezing.

According to recent studies, people suffering from seasonal flu are at risk to transmit the disease a day prior to development of symptoms for up to seven days after getting sick.

Children are more likely to be at risk for a longer period of time so it is best to consult a healthcare provider.

Emergency Warning Signs

If you suddenly become sick and experience any of the following warning signs, this is your cue to seek emergency medical assistance.

In the case of children becoming ill due to H1N1infection, the following warning signs may require immediate medical attention:

* Fast or difficulty in breathing
* Bluish or gray colored skin
* Insufficient amount of liquids
* Severe or continuous vomiting
* Lack of sleep or interaction
* Irritability
* Recovery from flu-like symptoms but the symptoms come back with fever and worse coughing

Among adults, the following emergency warning signs demand immediate medical attention:

* Trouble with breathing or shortness of breath
* Abdominal pains or pressure in the chest
* The individual suddenly becomes dizzy
* The patient is confused
* Severe or continuous vomiting
* Recovery from flu-like symptoms but the symptoms come back with fever and worse coughing

Prevention Is The Best Treatment

You can do your part in preventing the spread of the H1N1 virus. Here are some tips on how you can take part in efforts for preventing the spread of infection.

* Be aware. Obtain information about H1N1 by visiting the website of the CDC.

* Use a tissue in covering your mouth and nose when sneezing. Afterwards, throw the tissue in the trash.

* With soap and water, wash your hands after coughing or sneezing. If possible, use alcohol-based sanitizers.

* Refrain from touching your nose or mouth as this could lead to easy transmission of germs.

By being aware of swine flu symptoms, the spread of the H1N1 virus would easily be prevented.
