Very often when people start to learn about bird flu, they jump to the conclusion that fear, because the medicine advanced by quantum leaps since the 1918/19 influenza pandemic (worldwide epidemic), there is nothing. You are certainly right about the advances in medicine, since the extraordinary every respect. Unfortunately, when it comes to himself with a bird flu pandemic, these advances fall short in many areas. To the names of the most important:
1. Bird flu is byan influenza virus for which there are only four antiviral drugs approved in the U.S. The virus has extensive resistance to two of these drugs already and the resistance can develop in the remaining two, if they are used more widely in a pandemic. The other two drugs, Tamiflu (oseltamivir) and Relenza (zanamivir), are in extremely short supply, and even with planned increases in their production will remain in short supply for many years will. These drugs must be givenwithin 48 hours after onset of symptoms to be difficult, can make for a variety of reasons. Even if they are available and in view of the time, its effectiveness is less than 100 percent. And because the avian influenza is very different than the usual, we are accustomed to receiving higher doses for longer periods may be required for optimum effect.
2. While we have many wonderful antibiotic drugs are not effective against bird flu, because antibiotics only treatbacterial infections, viral infections can not. Antibiotics can be used to treat bacterial infections, that after a viral infection of the body are damaged, so that bacterial infections to take over ". This can happen, for example, if converted to viral pneumonia in bacterial pneumonia. This has not resulted in the 1918/19 Spanish flu happened in any way, nor in the 2003 SARS epidemic, and it seems not a major factor in the deaths that are caused by previouslyAvian flu. Hence all our sophisticated antibiotics will not help much with the bird flu.
3. The most common cause of death of 1918-19 influenza pandemic, the SARS epidemic of bird flu is acute respiratory distress syndrome (ARDS). The viruses from these diseases cause severe damage to the lungs, which results in ARDS. Numerous treatments have been tried but not as a rule. Patients with ARDS, mechanical ventilation, ie they must be on a mechanicalRespirator. These machines are expensive, and the supply in the United States is only slightly above the demand during regular flu season. Simply put, if the bird flu pandemic strikes, it is not enough of these machines and people who develop ARDS, it does not have access to this potentially lifesaving treatment.
4. It will not be enough isolation rooms place to the large number of patients with avian influenza, which will cause more people to become ill throughContact with people with bird flu. Likewise, it is not enough, some medical devices, coupled due to the increased demand for some products with a reduced supply because of our dependence on a global supply chain, external manufacturing, and just-in-time delivery. It will not be sufficient personal protective equipment (eg disposable gloves, N95 masks, gowns, face shield or goggles), head caps and shoe covers face, increase the exposure andInfection.
5. Over the next pandemic, it is not enough beds in hospitals for all the sick people with bird flu. Makeshift "hospitals" will be set up outside the existing hospitals to care for all sick patients.
6. An effective vaccine is yet to be developed, and the opportunities that we are still being developed before a pandemic, there is practically nonexistent. Once a vaccine is developed, it will be months after the start of the pandemic, and many peoplehave already become ill. Because we have no natural immunity against this new virus, we can develop two vaccination shots need for adequate immunity. This makes the implementation of an immunization program more difficult and reduces the amount of vaccine available to everybody.
Avoid vaccines, such as antiviral drugs are not 100 percent effective either an infection or minimize symptoms once infected. A surprising new report (a) found only limited use of influenza vaccines:"For people over 65, the vaccines are" manifestly ineffective "in preventing the flu, pneumonia and hospital admissions, deaths, although it had a bit of pneumonia to reduce, by up to 30 percent."
After the Influenza Vaccine Supply (IVS) International Task Force "Whatever scenario, even the most optimistic, the worldwide [vaccine] production capacity is clearly inadequate in the event of a pandemic."
7. The shortage of nurses and otherHealth care personnel will be significant, because of excessive people with bird flu and thus a higher morbidity and mortality among the awareness of health workers, and because a high proportion is not easy to decide to come to work. A similar situation occurred in New Orleans by Hurricane Katrina, when 250 members of the police (one sixth of the force) to leave their jobs during the hurricane and flooding. It also came before in Toronto during the SARS outbreak, when some nurses andothers remain active in the health field workers submitted their resignations (though many were convinced of).
The shortage of nurses, who already was a major problem in the United States, recently launched by Keji Fukuda of the influenza branch of the Centers for Disease Control and Prevention (CDC) highlighted. According to Fukuda, the scientists race to prevent what could be millions of deaths, is of a flu pandemic, but what she could travel to the simple shortage of nurses and hospital beds. He said: "NoNo matter how good the medical technology if we are not working in healthcare workers and hospital beds for sick people in care, they ask, it's not a good situation. "
And it's not just the limited number of nurses, it is also a question of whether workers would be working in the health sector to work during a bird flu pandemic. A recent article (b) reports on the disturbing findings of a survey of 6,000 health care works in and around New York City:
"An acceptanceblown away by Hurricane Katrina is that if the government does nothing else, at least it's protects the health and safety of people.
The Mailman stated School of Public Health at Columbia University, New York, to consider how many working in the health field workers said they would be more to work, depending on the type of emergency. There was good news: 87 percent of the 6,000 employees in 47 facilities in and around New York said they would be able to go to in case of a mass casualty survey workIncident, and 81 percent for an ecological disaster.
Only 61 percent would show, however, for a smallpox epidemic, only 48 percent for a SARS epidemic and 57 percent for a 'radiological event. "
This is a problem, right? Less than half expect the health professionals that work during a SARS [or bird flu] epidemic, and less than two thirds of the way, if terrorists known as a dirty bomb in the financial district.
"Although we might assume thatHealth workers have a duty to respond, to show that high-impact events, our results indicate that personal obligations, and concern for his own safety, play a central role in the willingness of workers report to work, "said Kristine Qureshi, a researcher in the department of epidemiology at Columbia University. "
And so "modern medicine" is, no matter how advanced, clearly have difficulty dealing with a bird flu pandemic. In a sense, the next pandemic couldwell be analogous to the Hurricane Katrina situation, with a mass of confusion, lack of resources, seen dead bodies, acts of cowardice and heroism, financial disaster, panic, and every emotion possible, nothing is what we are seeing is used in the U.S. be, shocking.
Partly because of the limitations of the two administrations and healthcare and the need for individuals for the coming bird flu pandemic prepared. There are four specific areas that need to be addressed, as Iwrote in a previous article (which can be accessed on our website.)
