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.

An Overview of Swine Flu

Swine flu or influenza is a condition caused by strains of subtypes of Influenza A virus called H1N1, H1N2, H3N1, H3N2, and H3N3. These viruses are common in pigs located in midwestern United States, Canada, South America, Mexico, Mainland China, Japan, Taiwan, Europe, and other Eastern Asian countries.

Transmission of influenza virus from swine to humans is relatively uncommon and does not always result to human influenza but often leads to production of antibodies in the blood. When properly cooked, pig meat does not have the potential of passing the virus. Transmission that leads to human influenza is called zoonotic swine flu.

People who work with pigs, particularly those with direct exposure, are at greater risk of being infected with swine flu. Towards the middle of the 20th century, identification of influenza subtypes became likely paving the way for an accurate diagnosis of transmission to humans. Since then, 50 infections have been confirmed and recorded.

It is rare for these strains of swine flu to be transmitted from one human to another. In humans, the symptoms of swine flu are similar to common influenza as well as influenza-like illness such as chills, sore throat, fever, coughing, muscular pains, severe headache, and general discomfort.
The 2009 swine flu outbreak in humans was caused by a new strain of influenza A virus subtype H1N1 which have genes that closely resemble swine influenza. The root of this new strain is not known. According to the World Health Organization for Animal Health, this new strain has not been isolated in pigs. It is capable of human-to-human transmission and manifests the normal symptoms of influenza.

Swine can be infected with human influenza such as the case of the 1918 flu pandemic and the 2009 flu outbreak. Swine flu was first proposed as a disease associated with humans during the 1918 flu pandemic. During that time, pigs became simultaneously sick with humans.

Influenza virus as a cause of disease in pigs was first identified in 1930. For the next six decades, strains of swine influenza became almost exclusively H1N1. From 1997 to 2002, new strains of three varied subtypes and 5 different genotypes were identified as the cause of influenza among pigs in North America.

From 1997-1998, H3N2 strains developed. They included genes acquired through reassortment of human, avian, and swine viruses and have been a principal cause of wine influenza in North America. Reassortment between H1N1 and H3N2 resulted to the development of H1N2. In Canada, a strain of H4N6 resulted from the reassortment of avian and swine flu but was isolated on a single farm.

The H1N1 variant of swine flu is one of the descendants of the strain that brought about the 1918 flu pandemic. While persisting in pigs, the descendants of the 1918 virus have also been transmitted throughout the 20th century which resulted to the usual seasonal influenza outbreaks.
It is interesting to note that direct infection from pigs to humans is rare, with only 12 confirmed cases in the United States since 2005.

However, since the influenza strains remain in the pigs after they have disappeared in the human population can make these pigs a reservoir where the influenza virus could survive and later on transmitted to humans as soon as their immunity to the strain is no longe effective.

Swine flu has been recorded as zoonosis in humans several times, oftentimes with limited distribution and rarely with massive distribution. Swine outbreaks are common and can lead to significant economic losses in the industry, mainly leading to stunting and expanded market time. Swine influneza, for instance, the British meat industry has experienced 65 million of losses annually.

The Lowdown on The 2009 Swine Flu Outbreak

The 2009 outbreak of swine flu or H1N1 virus is recently hugging the limelight due to the potential harm or effects it can have on a patient or on a community. Unfortunately, the source of the virus still cannot be traced.

Before the first case in the United States was discovered, the illness was believed to have started in Mexico which eventually spread to other countries. Recently, the first case of swine flu was reported in
Costa Rica. Alarmed that it could grow into a worldwide flu epidemic, the World Health Organization of the United Nations and the Center for Disease Control Prevention (CDC) in the United States raised its pandemic alert level to Phase 5, which signifies that a “pandemic is imminent.”
While experts believed that the recent outbreak is not as fatal as previous epidemics, such as the SARS virus, health officials believe that the number of cases could go up as the new flu is expected to make its way throughout the United States.

The new swine influenza strain is apparently a new variant of four strains of influenza A virus subtype H1N1. According to the Center for Disease Control and Prevention, one of the strain is endemic in humans and birds and a couple are endemic in pigs.

However, according to scientists the 2009 H1N1 outbreak is of swine origin which is associated with the virus isolated in North America in 1998. To hasten understanding of the current outbreak as well as in coming up with a vaccine, scientists from Canada have completed the full genetic sequencing of the H1N1 virus.

The new strain of H1N1 has become widespread in Mexico and the United States with confirmed cases in 18 countries and suspected cases in 42 others. Travelers have been warned not to travel to affected countries such as Iceland, Singapore, Thailand, South Korea, Hong Kong, Singapore, to name a few.

In addition, warnings have also been issued warnings to visitors of countries affected by the outbreak. It is advisable for visitors to see the doctor right away if they experience flu-like symptoms.
In Mexico, schools, universities, and all public events were suspended from April 24 to May 6, 2009. In the United States, over 400 schools were closed as of May 3, 2009, which included schools in Texas and about 250,000 confirmed or probable cases.

Dr. Keiji Fukuda, who is the Assistant Director-General for Health Securiy and Environment of the World Health Organization confirmed that efforts to control the outbreak is already too late and should now focus on lessening the effects of the virus. He also clarified that closing borders or limiting travel to infected areas will do little in stopping the spread of the H1N1 virus.

On April 28, 2009, the Center for Disease Control and Prevention suggested that as much as possible, people should avoid non-important travel to Mexico.

According to Dr. Ira Longini, who is an expert in the mathematics and statistics of epidemics, staying at home, seeking medical care, closing public venues, and making anti-flu medicines accessible can help reduce the sickness by almost two-thirds.

Finally, according to Dr. Longini, the focus of efforts is to slow transmission until there is a vaccine that can be developed and made available for controlling swine flu outbreaks.

Swine Flu Vaccine Productions

To discuss and make strong decisions to fight the widespread Swine Flu, the World Health Organization set a meeting with the vaccine manufacturers together with other health experts to stop the Swine Flu Outbreak. Different Pharmaceutical companies are ready to begin making a Swine Flu vaccine but as the virus may alter, there are questions formed:

How much should they have to produce? How will the government distribute the vaccines to the infected areas? Who should get it, babies, youngsters, adults, men, women, pregnant?

Most flu vaccine companies mentioned that they can only make one vaccine at a time: either seasonal flu vaccine or pandemic vaccine. Production takes months and it is impossible to switch halfway through if health officials make a mistake. Vaccine makers can make limited amounts of both seasonal flu vaccine and pandemic vaccine though not at the same time but they cannot make massive quantities of both because that exceeds manufacturing capacity.

Even if we are in the modern era, still the health officials have a big problem to solve the spreading of deadly swine flu is, and whether they will need more seasonal flu vaccine or swine flu vaccine. Scientists are not sure the effectiveness of a vaccine, if the swine flu will transmute. Only two billion doses of swine flu vaccine could be produced annually based on the estimation of World Health Organization officials, though the first batches wouldn’t be available for four to six months.

A “seed stock” to make the vaccine, which should be ready and it will be distributed to manufacturers worldwide so they can start producing the vaccine is now on the go as the U.S. Centers for Disease Control and Prevention works on. After the vaccine manufacturers get the seed stock, they won’t know how many doses of vaccine they can make or how long that would take.

Including vaccine producer, GlaxoSmithKline PLC, the World Health Organization is under negotiation process to save some of their swine flu vaccine for poorer nations. A couple of years ago members of the rich nations like United States, Switzerland, France, Denmark, Canada and Britain signed deals with the vaccine makers to guarantee them pandemic vaccines as soon as they’re available.

Cipla (The pharmaceuticals giant in India) instructed by the World Health Organization to make a generic version of Tamiflu antiviral drug. Tamiflu also known as oseltamivir, one of the two antiviral drugs to treat the Swine Flu. Then WHO said Cipla’s generic version was more effective than the original made by Swiss firm Roche Holding AG and would hopefully make the drug more accessible to the third world countries. As we all know that Indian pharmaceuticals produce drugs in very affordable prices.

North America has been the hardest-hit continent for the Swine Flu virus that kills two Americans from Texas (including a pregnant woman) and one in Washington. If the vaccine productions are enough to all suspected Swine Flu carrier, it wont happen again that a simple pregnant woman died fighting the virus.

Through this article, we will inform the public of an early planning and prevention against Swine Flu for their safety. Consult to the Health Officers about planning and prevention against the virus. According to an unidentified source that one out of three Americans can only take the Tamiflu.
