Pandemic InfluenzaToday, several viruses are spreading around the world, and influenza is an especially common virus. In human history, pandemic influenza has spread on a worldwide scale and infected many people. This influenza has killed many people in the world.  We would like to state how influenza effects our body, how did this influenza spread around the world, and three major pandemics.First, how the influenza effects our body. An infected body with the killer flu was found in the artic, the body was sent to scientists in Canada at the national microbiology laboratory, which reconstructed the whole virus like a puzzle, and they made scientific tests on monkeys to see how they reacted to the virus, the scientist discovered that flu attack in 24 hours. For example, in 1918 the Spanish flu was the most dangerous virus that killed 50 million of people or one third part of the world population became infected with this virus. The most affected were people around 5 years old and 20-24 years old. (NCIRD, 2018) Next, how did this flu spread around the world? Pandemic flu occurs when a new strain of the influenza virus is transmitted to humans from animals. For example, the 1918 influenza strain become widespread when sick soldiers were transported between World War I and the conclusion of World War II. Several scientists argued that it came from China, a country where animals and humans often live close. The influenza strain bred in China and spread to the world. The 1918 influenza struck American German and Austrian soldiers first, then it expanded into their civilian population. (Barry, 2009) Third, Since the last 100 years, we have gone through three major pandemics. The first pandemic was the Spanish virus of 1918 killing 50 million people, going through the Asian flu of 1957 leaving a balance of 1 million deaths and the Hong Kong flu of 1968 leaving. As a result, around 1 million deaths but the scientists agree that there will be a new epidemic in the future, so they are preparing to face it. Several countries have created contingency plans due to the almost certain possibility of a future pandemic with increased attention to SARS and bird flu, which is why they work on the development of emergency plans and vaccines for their prevention. First, governments have been working on emergency plans to keep their population safe. Governments have focused on contingency plans capable of preventing a pandemic because they are aware of the imminent possibility of a pandemic. They will be giving to their population access to the necessary supplies. For example, antiviral drugs necessary for the prevention or control of a possible pandemic. In addition, the most difficult challenge that the scientists will face is having to been working on the development of possible drugs capable of preventing some type of virus that can develop in a pandemic. They are developing medicines that could treat these possible pandemics because they are working with the national influenza reference centres around de world to prevent a future pandemic. For example, many scientists are focused on the development of possible vaccines for Sars and Avian flu, since they are the two viruses most likely to become a pandemic. (Dunne,2005)Next, we would like to mention some solutions for this problem. If you want to prevent or don’t get the killer flu a solution can be using soap for your hands and covering your mouth to don’t spread more germs, using a lot of antibacterial soap can be preferable, but If soap and water are not available, use an alcohol-based hand rub and avoid touching your eyes, nose and mouth. First of all the killer flu is a virus not a bacteria recommends that you wash your hands for the length of time it takes to about 15 to 20 seconds. Schaffner says that while 30 seconds would be ideal, he admits that this isn’t always possible. (Monto, 2008 ) As one of solutions, people should wear a mask. People tend to breath mouth. Virus is easier to enter from mouth than nose. Also, it is said that influenza patients release about 100,00 viruses per cough and about 2 million viruses per sneeze. When they wear a mask, we might prevent to spread influenza. (Cherney, 2015)Second, we need to integrate to our daily life the practice of good cleaning habits. Starting by cleaning and disinfecting all surfaces that are much frequented at home, especially when someone around us is sick because this are surfaces that may be contaminated with germs such as flu. Trying to avoid close contact with sick people contributed to prevent getting infected, also covering your nose and mouth with a tissue when you cough or sneeze is an effective way to prevent the spread out of a virus. After using a tissue, you must throw it in the trash and wash your hands. Otherwise, the germs can be spreaded out by this way.In conclusion, influenza is a disease that infects many people at once and even now it is still prevalent around the world. Once influenza spread, the virus effects many people. We should be prevented so that pandemic influenza like 1918 will never happen again.CitationsNICRD.
