Influenza treatment People with the flu are advised to get plenty of rest, drink plenty of liquids, avoid using alcohol and tobacco and, if necessary, take medications such as acetaminophen paracetamol to relieve the fever and muscle aches associated with the flu.

In Arctic temperatures, it does not degrade at all. Louis, Missouri, with medicine and babies Historian Nancy Bristow has argued that the pandemic, when combined with the increasing number of women attending college, contributed to the success of women in the field of nursing.

H5N1 is different from all previously known highly pathogenic avian flu viruses in its ability to be spread by animals other than poultry.

Bird flu could be as deadly as the 1918 Spanish flu pandemic

Most of the victims were healthy people in the prime of life. Until a universal vaccine is created, "governments must inform the public on what to expect and how to act during a pandemic," said van de Sandt. The United States and these international partners have led global efforts to encourage countries to heighten surveillance for outbreaks in poultry and significant numbers of deaths in migratory birds and to rapidly introduce containment measures.

It can also occur if an intermediate host such as a pig—which is susceptible to avian, human, and swine influenza—becomes simultaneously infected by influenza viruses from two different species and the viruses exchange genetic information to acquire completely new antigens, a process called genetic reassortment.

Countries with poultry or wild birds killed by H5N1 and has reported human cases of H5N1 Countries with poultry or wild birds killed by H5N1. Before our project, GenBank contained only 5 other complete genomes from Europe for the — period, and it contained no whole genomes from the Middle East or northern Africa.

Humans with H5N1 have typically caught it from chickens, which were in turn infected by other poultry or waterfowl. The disease would usually only affect a certain area for a month before leaving, while the war, which most had initially expected to end quickly, had lasted for four years by the time the pandemic struck.

Compared with previous pandemics, the swine flu was relatively mild, despite killing up topeople worldwide. Hemagglutinin and neuraminidase molecules cluster into a bulge in the cell membrane. Department of Statethe U.

Influenza Type A Viruses

There is one ominous sign. Taubenberger says the bird virus appeared in humans "a couple of years" before Next Year Flu Science. That could still happen to the H5N1 bird flu. Because the H5N1 virus targets cells responsible for repairing damage to the lung lining, seeping wounds are slow to heal.

He provides data that the viral waves hit the Central Powers before they hit the Allied powers, and that both morbidity and mortality in Germany and Austria were considerably higher than in Britain and France. As part of those studies, scientists analyzed viral gene samples taken from flu victims preserved in the Alaskan permafrost.

One of the earliest reports of an influenza-like illness comes from Hippocrateswho described a highly contagious disease from northern Greece ca.

Those with the emergency warning signs should visit the emergency room at once. Department of Statethe U. Army Camp Hospital no.

The study said governments could use the communicative power of the internet to help spread awareness and instructions in the event of a new pandemic. In most cases, it causes minor sickness or no noticeable signs of disease in birds. Normally, a highly pathogenic avian virus is not highly pathogenic to either humans or nonpoultry birds.

A Moving Target Shortly after scientists identified the influenza A virus, researchers began work on creating a flu vaccine, with the first clinical trials commencing in the mids.

That way, the two strains can share genetic material to make a new variety. The bug seemed to need several changes in every one of its eight genes. The relative importance of these three modes of transmission is unclear, and they may all contribute to the spread of the virus.

As for a vaccinework cannot start on it until the emergence of a new virus, and we predict it would take six to nine months to develop it.

This current deadly strain of H5N1 is unusual in being deadly to so many species, including some, like domestic cats, never previously susceptible to any influenza virus.

HA codes for hemagglutininan antigenic glycoprotein found on the surface of the influenza viruses and is responsible for binding the virus to the cell that is being infected.

How Bird Flu Infects Humans and Why We Don't Spread It

This genus has one species, influenza B virus. Influenza B almost exclusively infects humans and is less common than influenza A. H5N1 exhibits seasonality in both humans and birds. (Spanish flu pandemic) (type A influenza, H1N1 subtype), which lasted from to It is not known exactly how many it killed, but estimates range.

H7N9 is a strain of flu virus that normally infects birds but has spread to at least humans in a number of outbreaks related to poultry markets. The influenza pandemic of killed more people than the Great War, known today as World War I (WWI), at somewhere between 20 and 40 million people.

Known as "Spanish Flu" or "La Grippe" the influenza of was a global disaster. a fifth of the world's population was infected. The flu was most deadly for people ages 20 to. The new research reveals that cells with H5N1 avian flu receptors are prevalent deep in the lungs of people who have died from infection, usually after direct contact with infected birds.

Spanish flu

For these gene swaps to occur, a bird or human (or intermediary host such as a pig) must be infected with both the avian H5N1 and a human influenza strain, researchers say. Feb 05,  · Changes in these proteins may answer questions as to how the current bird flu, affecting birds in countries throughout Asia, is infecting and killing some humans.
