4 June 11, 2009 the World Health Organization announced the 2009 H1N1 Novel Swine Influenza to be a Phase 6 Pandemic, the agency s highest alert level for an infectious disease. Up to this point the majority of those who have contracted the 2009 H1N1 virus have displayed only mild symptoms. The rapid spread of this disease across 74 countries and the potential for the virus to turn deadly on a wide scale requires a heightened level of vigilance for all of us as we prepare for what may yet come.

5 What is H1N1 novel influenza (formerly known as swine flu)? H1N1 novel influenza is a respiratory illness caused by a virus. H1N1 is a certain kind of influenza that can cause infection in humans.

6 The symptoms are similar to seasonal flu: fever (above 100 F) cough g sore throat stuffy y nose in some cases diarrhea and vomiting

7 How does H1N1 influenza spread? Person to person transmission has been identified as the primary means of infection in the 2009 H1N1 pandemic influenza. Information from the World Health Organization indicates that transmissibility of this virus is substantially higher than that of seasonal influenza (Thorner, 2009).

8 Simply stated..transmission can occur When a person with the flu coughs or sneeze into theair. By touching something with flu viruses on it By touching something with flu viruses on it and then touching your eyes, nose, or mouth.

9 What can I do to protect myself from getting sick? Cover your nose and mouth with a tissue every time you cough or sneeze. If you don t have a tissue, sneeze or cough into your sleeve. Wash hands often with soap and water or an alcohol based hand cleaner. Avoid touching your eyes, nose or mouth.

10 Avoid close contact with people p who are sick, if possible. Stay healthy: eat nutritious foods, get enough sleep, and exercise.

11 What should I do if I get sick? Call your healthcare provider to determine if you need to be evaluated. Stay home and avoid contact with other people as much as possible to keep from spreading your illness to others Get plenty of rest Drink clear liquids to prevent dehydration

12 Individuals id at risk ik The CDC has identified certain groups of people who are at increased risk of becoming more severely ill if they become infected with seasonal influenza. Itappears that the samegroups areat increased risk It appears that the same groups are at increased risk with Novel H1N1 influenza. These groups include:

13 Children < 5 years, particularly those <2 years Persons aged 65 years or older Women who are pregnant Adults and children who have chronic health conditions (such as asthma, diabetes) Adults and children with a lowered immune system Residents of nursing homes and other chronic care facilities.

14 H1N1 Novel Influenza Statistics In Minnesota, H1N1 novel influenza activity peaked during the third week of June. Low numbers of hospitalized cases of H1N1 novel influenza as well as seasonal influenza continue to be identified. 3 deaths have been associated with H1N1 novel influenza infection. As of July 31, 2009, the median age of hospitalized cases is 12 years; most hospitalized cases (>80%) are residents of the 7 county Minneapolis St. Paul metropolitan area.

15 Asthma is currently the most frequently identified chronic underlying health condition noted among patients hospitalized with H1N1 novel influenza 78% of hospitalized patients with H1N1 novel influenza had at least one risk factor for severe complications from influenza. H1N1 novel influenza currently represents >90% of all influenza A positive samples tested at MDH.

16 Viruses Types Influenza A virus Can infect both human and animal species May rapidly spread in epidemic or pandemic fashion in animal species or humans Influenza B virus Human virus. Occasional epidemics, not associated with pandemics Influenza C virus Human virus associated with mild illness. Not associated with epidemics or pandemics

17 Hospitalized Surveillance for Influenza Surveillance for the influenza season started October 1, Hospitalized cases of influenza are reported to MDH. The first laboratory confirmed, hospitalized influenza case (seasonal influenza A) occurred in early December. The first hospitalized seasonal influenza type B case occurred in early January. Peak seasonal influenza activity lasted from early February to early March. During this time, seasonal influenza A virus infection accounted for the majority of hospitalizations. Seasonal influenza B virus accounted for the majority of hospitalizations from late Marchthrough mid May.

18 The first laboratory confirmed, ato hospitalized edcase of H1N1 novel influenza occurred in mid May and has since accounted for the majority of influenza hospitalizations. Hospitalizations for H1N1 novel influenza infection peaked during mid to late Juneand has decreasedsignificantlyover significantly the past several weeks. While data over weeks 28 and 29 are preliminary, currently activity of H1N1 novel influenza appears to have waned in Minnesota.

22 Pandemics happen. The 2009 H1N1 novel swine origin influenza A pandemic is a fast spreading human to human virus that will very likely sweep through an area and then return in successive waves over a period of several years. In its first sweep through the Northern Hemisphere since its first appearance in Mexico in March 2009 it has caused mild to moderate symptoms moreoftenoften than severe illness and death. Influenza viruses change however and the nextsweep through may well show a dramatic increase in flu related death. Preparation for the return of the 2009 pandemic flu must occur.

23 What Can We Do?? Remember Education is the Key to Prevention!! MSC ST has a well defined plan that provides for all faculty, staff and students to be updated through and web site postings We ask that all faculty read the informational sheet to your students next week. Our goal is every day every class
