Europe: H1N1 Overview: H1N1 (also known as the 2000 Influenza A or swine flu) is a new type of influenza that has spread rapidly among humans around the world since its appearance in April 2009. Influenza is a viral infection that spreads from person to person principally when people cough or sneeze, or by direct or indirect contact with respiratory secretions from infectious persons that are on their hands or on surfaces. 1 This new virus was first detected in people in the United States in April 2009. The Center for Disease Control and Prevention in 2009 reported that the virus spread from person-to-person worldwide, almost in much the same way that regular seasonal influenza viruses spread. On June 11, 2009, The World Health Organization (WHO) declared that a pandemic of 2009 H1N1 flu was underway. 2 H1N1 has been discovered to contain the genes of pig, birds and human, in a combination that is rare and has never been observed before. 3 Symptoms of the H1N1 virus include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people also experience vomiting and diarrhea. Others may only have respiratory symptoms without a fever. People with swine flu may be more likely to feel nauseous and throw up than people who have seasonal flu. But a lab test is the only way to know for sure. 4 Severe illnesses and deaths have occurred as a result of this virus. 5 Soon after the pandemic emerged there was a drug, Pandemrix, made by a British drug maker, GlaxoSmithKline to prevent the virus. This vaccine is allegedly the cause of the narcolepsy, an incurable sleepy disorder. In August 2010 the pandemic was declared over by the World Health Organization. Europe has now entered a new inter-pandemic phase of seasonal influenza. 6 Scientists are now conducting massive research to further understand this pandemic, as well as to know if Pandemrix is a direct cause of narcolepsy. Aspects of the Problem Containing the spread of diseases For H1N1 there is some hesitancy in using the terms containing or delaying to describe the prevention of the infection spreading. The term containment was not recommended by the World Health Organization (WHO) to explain H1N1 because when it emerged, the rapid spread of the virus was beyond a delimited area, which is why the term delaying is preferred. 7 Furthermore, the WHO uses a six-phase approach for easy incorporation of new recommendations and approaches into existing 1 national preparedness and response plans for pandemics influenzas. 8 The approach is as follows: phases 1-3 are predominately animal’s infections and a few human infections; phase 4 is a sustained human-human transmission, which is where the term containment is preferred; and phases 5-6 are widespread human infections (a Pandemic). 9 The H1N1 was considered to be between phases 5-6, due to the quickness of which the virus spread from people to people around the world. 10 If the virus was considered to be in phase 4 or below then the term containment would be preferred. There are two main preventive measures of the spread of the virus under delaying that the European Centre for Disease Prevention and Control (ECDC) reports in their June 2009 Influenza A Report (1) case-finding: detecting imported infections and first generation transmissions; and (2 ) taking actions to prevent their turning into chains of transmission and outbreaks, notably through vigorous contact tracing, treatment and/or quarantine of contacts. Within the same ECDC report, there are additional delaying practices for travellers and the general population in preparation for the impact of the virus in Europe that consist of: providing relevant information, isolating symptomatic persons, starting early treatment of persons under investigation, giving antivirals or alerting them to watch for symptoms. The main practical difficulty with the delaying strategy is to practice casefinding vigorously and to extend action to contacts of ill incoming travellers when transmission starts occurring in the community, which can be very labor-intensive. 9 The ECDC report, states that vigorous case finding and contact tracing is hard work and tiring for field staff. As they prepared with limited time for the pandemic, the potential early exhaustion and undermining of the public health workforce was a key concern. 10 Managing the Long-Term Consequences The WHO currently considers H1N1 to be in the post-pandemic period. This means that the influenza disease activity has returned to levels normally seen for seasonal influenza. It is also expected that the pandemic virus will behave as a seasonal influenza A virus. 11 The WHO suggests that at this stage, it is important to maintain surveillance and update pandemic preparedness and response plans accordingly, as well as to be prepared for the possibility of an intensive phase of recovery and evaluation. While H1N1 is no longer considered a pandemic, it's still important for people to protect themselves from getting it. Like seasonal flu, it can cause more serious health problems for some people. The best protection is to get a flu vaccine every year. 12 2 Even with the availability of the vaccine against 2009 H1N1 virus, the CDC stills suggests the following measure are important because they can prevent the spread of other viruses that cause respiratory infections:13 Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it. Wash your hands often with soap and water, especially after you cough or sneeze. If soap and water are not available, use an alcohol-based hand rub. Avoid touching your eyes, nose or mouth. Germs spread that way. Stay home from work or school and limit contact with others if sick to keep from infecting them. Communication Issues From a report on Risk Communication Research by the Department of Sociology at the University of Geneva states that among the general public, H1N1 was often associated with traditional seasonal flu. Therefore, H1N1 risk was thought to be low. The report also shows that public distrust in different actors of the pandemic crisis, in particular governments, the media, pharmaceutical industries, and international and national health authorities. Nevertheless, a report from the European Commission in November 2009 shows that health professionals were the most trusted sources of information among EU citizens.14 There are many myths and rumors in regards to H1N1, such as during the H1N1 crisis; Mexicans were depicted as unhygienic subjects and circulators of disease. Mexicans were blamed for the “Mexican flu,” pigs were blamed for the “swine flu,” and birds for the “avian flu. Mexico was one of the countries during the early stages where the breakout took place, however is no shape or form means individuals within Mexico have a bad hygiene. Furthermore, H1N1 is a multifaceted virus that is a combination of the human, pig and bird virus interchangeably. 15 A couple other common myths and facts are as follows: 1. You can catch it from eating pork a. Swine flu is spread from one person to another like any other flu, not through the eating of pork, unless an infected human has sneezed on your ham sandwich. And even if eating an infected pig could spread it, the influenza doesn't survive contact with cooking temperatures to at least 160 degrees Fahrenheit. 2. A mask will protect you 3 a. Wearing a mask is a good idea if you work in a hospital or primary care center and make contact with patients who have flu symptoms. Using a facemask isn't a fail-safe against catching swine flu. And, after a while, masks get uncomfortable. Finding and Providing an Inexpensive Cure The best inexpensive cure for H1N1 is good hygiene, such as hand washing and cleaning, which is the most effective way of slowing the spread of flu. Antiviral medication is also offered to people at risk. 16 WebMD, a health information provider, reports that some of the same antiviral drugs that are used to treat seasonal flu also work against H1N1 swine flu. Antibiotics won't help, because a virus causes the flu, not bacteria. Oseltamivir (Tamiflu) and zanamivir (Relenza) seem to work best, although some kinds of swine flu are resistant to Tamiflu.16 These drugs can help you get over swine flu faster by relieving symptoms and reducing the risk of serious complications. WebMD also states that they work best when taken within 48 hours of the first flu symptoms, but they can help when taken later. 17 In order to lower a high temperature and relieve aches paracetamol or ibuprofen are acceptable to take. Water is also important to prevent dehydration. Lastly, there are a few natural remedies options to prevent H1N1, such as exercising to stay healthy and to boost one’s immune system to decrease the chance of being infected by the virus. If the recommended seasonal influenza vaccine is not available and if immunization against H1N1 is still needed, is the only time Pandemrix is used. On 25 September 2009, the European Medicines Agency (EMEA) approved Pandemrix, the swine flu vaccine produced by GSK.18 Reuters, a world’s leading source of intelligent information, reports that the Pandemrix shot was not used in the United States because it is a adjuvant vaccine and drug regulators are cautious of adjuvant vaccines. Reuters also reported that more than 30 million people in 47 countries during the 2009-2010 H1N1 swine flu pandemic received Pandemrix. 19 However, the largest concern of the drug is the side effect that has been reported to possibly be the cause of narcolepsy, an incurable sleeping disorder amongst hundreds of people, especially the youth in many areas in Europe. Narcolepsy is estimated to affect between 200 and 500 people per million and is a lifelong condition. 20 Much research is still underway concerning the details of the vaccine injury. 21 4 European 2009 Influenza Pandemic Timeline 22 Date 21-Apr-09 25-Apr-09 25-Apr-09 Event Two swine influenza cases reported in California 18 confirmed cases in Mexico (including 6 deaths) WHO declares the novel influenza A (H1N1) outbreak in Mexico and US 27-Apr-09 First confirmed cases reported in the EU (Spain and UK) 27-Apr-09 Declaration of Phase 4 by WHO and second meeting of the Emergency Committee 29-Apr-09 Declaration of Phase 5 by WHO 30-Apr-09 EMA prepares for approval of pandemic vaccines 03-May-09 First cases of in country transmission in Germany, Spain and UK 04-May-09 WHO statement on the H1N1 influenza situation 19-May-09 ECDC guidance on personal health measures to reduce risk of influenza transmission 11-Jun-09 Declaration of Phase 6 by WHO 15-Jun-09 First death in Europe reported from UK 01-Jul-09 UK moves from containment to mitigation of pandemic influenza 13-Aug-09 Health Security Committee statement on School Closures and Travel Advice 17-Aug-09 Call to action from WHO, IFRC, UNSIC, OCHA and UNICEF 19-Sep-09 Pandemic vaccine donations for the developing countries 30-Sep-09 Authorization of first two pandemic vaccines (Focetria & Pandemrix) by European Commission 01-Oct-09 European Medicines Agency recommends updating Tamiflu product information 26-Oct-09 Death of 13 year child in Toronto area (Canada) leads to dramatic change in attitude to immunization 04-Dec-09 European Medicines Agency advises of risk of fever among young children following pandemic vaccination 22-Dec-09 Adoption by the European Council of Recommendation on Seasonal influenza immunization 22-Jan-10 EMA recommends update of product information for Pandemrix to include more data from studies in children 08-Mar-10 ECDC's Forward look risk assessment for the 2009 pandemic influenza A(H1N1) and future influenza season 23-Apr-10 Marketing authorisations for Celvapan, Focetria and Pandemrix recommended to be switched to 'full' 30-Apr-10 ECDC ceases searching for announced deaths 10-Jul-10 WHO Director General announces that the world is no longer in a pandemic 5 Spread of 2009 Influenza Pandemic in Europe 23 Spread of H1N1 in Europe Late April Early May Mid May Late May Early June Mid June Late June 6 Works Cited 1 http://ecdc.europa.eu/en/healthtopics/Documents/09_07_personal_protective_measures_ECDC2009-0001-00-00-ENEN_final.pdf 2 http://www.cdc.gov/h1n1flu/qa.htm 3 http://ec.europa.eu/health/communicable_diseases/diseases/influenza/h1n1/index_en.htm#fragme nt0 4 http://www.webmd.com/cold-and-flu/flu-guide/h1n1-flu-virus-swine-flu 5 http://www.wndu.com/mmm/headlines/82824242.html 6 http://ecdc.europa.eu/en/healthtopics/H1N1/basic_facts/Pages/origin_of_virus.aspx 7 http://ecdc.europa.eu/en/publications/Publications/0906_GUI_Influenza_AH1N1_Mitigation_and_Dela ying_Strategies_for_the_Influenza_in_Europe.pdf 8 http://www.who.int/csr/disease/swineflu/phase/en/ 9 http://www.who.int/csr/disease/swineflu/phase/en/ 10 http://ecdc.europa.eu/en/publications/Publications/0906_GUI_Influenza_AH1N1_Mitigation_and_Dela ying_Strategies_for_the_Influenza_in_Europe.pdf 11 http://www.who.int/csr/disease/swineflu/phase/en/ 12 http://www.webmd.com/cold-and-flu/flu-guide/h1n1-flu-virus-swine-flu 13 http://onlinelibrary.wiley.com/store/10.1111/irv.12090/asset/irv12090.pdf;jsessionid=A1AA26E7E9A24126 067DB65C86CD0130.f04t02?v=1&t=i80eg3rf&s=3714c6a05688a02c0b16ac27c368638baa51f765 14 http://onlinelibrary.wiley.com/store/10.1111/irv.12090/asset/irv12090.pdf;jsessionid=A1AA26E7E9A24126 067DB65C86CD0130.f04t02?v=1&t=i80eg3rf&s=3714c6a05688a02c0b16ac27c368638baa51f765 15 http://www.discovery.com/tv-shows/mythbusters/about-this-show/h1n1/ 16 http://www.nhs.uk/conditions/pandemic-flu/Pages/Introduction.aspx 17 http://www.webmd.com/cold-and-flu/flu-guide/h1n1-flu-virus-swine-flu?page=2 18 http://orthomolecular.org/resources/omns/v08n10.shtml 19 http://www.reuters.com/article/2013/01/22/us-narcolepsy-vaccine-pandemrixidUSBRE90L07H20130122 20 http://www.reuters.com/article/2013/01/22/us-narcolepsy-vaccine-pandemrixidUSBRE90L07H20130122 21 http://orthomolecular.org/resources/omns/v08n10.shtml 22 http://ecdc.europa.eu/en/healthtopics/H1N1/Documents/110810_2009_pandemic_European_Timelin e.pdf 23 http://commons.wikimedia.org/wiki/File:Spread_of_Swine_Flu_in_Europe.svg 7
