As the 2009-2010 school year begins, the Massachusetts Department of Public Health (DPH) is providing updated guidance for schools concerning H1N1 influenza, seasonal influenza, and influenza-like illness (ILI). MDPH expects that both seasonal and H1N1 influenza will be circulating in the fall and is preparing for increased number of cases. The main changes in the guidance since the spring of 2009 are: 1) the importance of early seasonal flu vaccination; 2) the availability of H1N1 influenza vaccine; and 3) the shorter isolation period for those with influenza-like illness (ILI). The information provided is based on the most recent guidance from the Centers for Disease Control and Prevention (CDC). Our goal for the new school season is limiting transmission in schools in order to keep schools open and functioning as usual. Guidance is provided to schools in six areas:1. Seasonal Influenza Vaccination 2. H1N1 Influenza Vaccination 3. Control and Surveillance Measures for ALL Schools 4. Prevention and Education 5. Planning for the Flu Season 6. Decisions about School Dismissal or Closing 1. Seasonal Influenza Vaccination 2. H1N1 Influenza Vaccination • pregnant women Most people will need two doses, spaced approximately 3 weeks apart. The CDC and state health departments will be monitoring very closely for any signs that the H1N1 vaccine is causing unexpected adverse events, and the Vaccine Adverse Event Report System (VAERS) system is in place to report suspect events and investigate rapidly. More detailed information regarding target groups, allocation and administration of H1N1 vaccine will be distributed widely when the vaccine is available. A federal law known as the PREP Act provides protection from liability for anyone involved in any part of a vaccination campaign against H1N1 flu. 3. Control and Surveillance Measures for ALL Schools
• Students and staff with flu-like illness should be sent to a separate room, if possible, until they can be sent home. The ill individuals should wear surgical masks, if possible, and those caring for them should wear masks too. • All sick students and staff should stay home for at least 24 hours after they no longer have a fever. This fever-free period must be without the use of fever-reducing medicines, like Motrin (ibuprofen) or Tylenol (acetaminophen). They should stay home until at least 24 hours after they no longer have a fever even if they are taking antiviral medicines. Many people can expect to stay home for about 4 days: about 3 days with fever and one more day with no fever and no fever reducing medicines. However, the fever with influenza can last 2-5 days or more, so students and staff should be prepared to stay home as long as it takes to become fever-free for 24 hours.
• Encourage early medical evaluation of high-risk students and staff who have conditions that put them at increased risk of complications from the flu (heart disease, asthma, diabetes, pregnancy, weakened immune systems, and certain muscle and nerve disorders that can lead to breathing or swallowing problems). Try to identify these individuals now, so they can be promptly referred if they become ill. • Monitor absenteeism in students and staff. School nurses and student health centers should report higher than normal absenteeism or clusters due to influenza-like-illness to your local health department and to the DPH Immunization Program at 617-983-6800. An epidemiologist is available to provide further guidance on surveillance and outbreak control. • Otherwise healthy students and staff experiencing mild ILI do not need to seek medical care since this would place a difficult burden on the health care system. Therefore, if a child is out with ILI and has stayed home according to the guidelines above, they do not need a note from their doctor or to have had a flu test in order to return to school. • A negative rapid influenza test result can occur even when someone does have influenza (a “false negative”). Rapid influenza tests, used in some medical offices and emergency rooms, can help in the diagnosis and management of patients with signs and symptoms of influenza. If they are positive, the likelihood that the patient has influenza is very high. However, if they are negative, the patient can still have influenza. Therefore, a negative rapid test can not be used to shorten the exclusion period. • A health care provider’s note recommending a child with ILI return to school does not supersede the public health exclusion guidance. 4. Prevention and Education • Emphasize and remind students and staff about the importance of proper hand washing and cough etiquette in preventing the spread of diseases. Provide the time and supplies for students and staff to wash their hands when needed. Place hand sanitizer in each classroom to facilitate regular hand hygiene. Place boxes of tissues in each room. • Ask teachers or school nurses to demonstrate and teach proper hand washing and cough etiquette in each class, and to explain why it’s important. Educational materials, posters, etc., are available on the DPH website, www.mass.gov/dph/swineflu. Send hand washing or other flu control educational materials home to parents and ask for their assistance in reinforcing these messages with their children. • Clean surfaces and items that are more likely to have frequent hand contact (“high touch surfaces”) with your normal cleaning agents according to your routine schedule. Once respiratory secretions containing the virus dry out, the virus is no longer effectively infectious. Reassure parents and staff that there is no need for special disinfection or decontamination efforts and that the main focus should be on hand washing and cough and respiratory etiquette. 5. Planning for the Flu Season However, DPH recognizes that, on a case-by-case basis, some schools may need to consider the dismissal or closure of a facility if the extent of influenza-like illness has impaired the school’s ability to perform its educational functions, or it is a facility where most of the students are pregnant or medically fragile*. School officials must discuss their situation with their local board of health and/or DPH prior to making this determination. Schools should prepare for the possibility of school dismissal or closure before facing this decision. This includes asking teachers, parents, and officials in charge of critical school-associated programs (such as meal services) to make contingency plans.
Factors to consider in school closure decisions: 1. Absenteeism that is substantially higher than expected for the facility at this time of year
If a decision to dismiss or close a facility is made in consultation with the local board of health and/or DPH, the following should be considered: • Cancellation of all school-related gatherings and discouraging parents and students from congregating outside of the school.
CDC has developed Preparing for the Flu: A Communication Toolkit for Schools (Grades K – 12 which contains helpful detailed information. Included are questions and answers, fact sheets, template letters and educational materials. This Toolkit should be considered an additional resource for you and is available at: http://www.flu.gov/plan/school/. |
