We will write a custom essay sample on Infectious Disease and Health Protection Agency or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Where large numbers of people come in contact with each other, the risk of spreading infection increases. This is particularly so where people are in close contact and share eating and living accommodation. It is important to have guidelines to protect service users, staff and visitors. Adopting these guidelines and standard infection control practices will minimise the spread of infectious diseases to everyone. External Factors If you or someone in your immediate family has a â€Å"Notifiable Disease† such as Measles (see 1. 3) or infection such as Impetigo, diarrhoea, vomiting or Scabies, please inform your line manager before coming to work. If you regularly visit people in hospital please be aware of the potential risk of cross infection to yourself and the person you are visiting. Above all when dealing with service users and their families we must all remember we are dealing with people. There will be personal issues of privacy and sensitivity, which we must handle with tact and discretion at all times. What are Infection Control Practices? Infection control practices are ways that everyone (staff, service users volunteers) can prevent the transmission of infection from one person to another. They are practices which should be routinely adopted, at all times with every individual, on every occasion, regardless of whether or not that person is known to have an infection. 1. 2 INFECTION CONTROL GUIDANCE – cont. include: 1. 3 NOTIFICATION OF INFECTIOUS DISEASES A number of infectious diseases are statutorily notifiable under The Public Health (Control of Disease) Act 1984 and The Public Health (Infectious Diseases) Regulations 1988. There are three main reasons for such notification. So that control measures can be taken To monitor preventative programmes For surveillance of infectious diseases in order to monitor levels of infectious diseases and to detect outbreaks so that effective control measures can be taken. All doctors diagnosing or suspecting a case of any of the infectious diseases listed overleaf have a legal duty to report it to the Proper Officer of the Local Authority, who is usually the Consultant in Communicable Disease Control based at the Health Protection Agency. Notification should be made at the time of clinical diagnosis and should not be delayed until laboratory confirmation is received. Infections marked (T) should be notified by telephone to the Consultant in Communicable Disease Control (see Section 5) and confirmed by completion of a written notification form. 1. 3 NOTIFICATION OF INFECTIOUS DISEASES – cont.

Other specific diseases are designated by the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 as â€Å"Reportable Occupational Diseases† e. g. Legionellosis. Please contact the Health Safety Team for further information (see section 5 for details). 1. 3 NOTIFICATION OF INFECTIOUS DISEASES – cont. Notification of suspected outbreaks An outbreak is defined as two or more cases of a condition related in time and location with suspicion of transmission. Prompt investigation of an outbreak and introduction of control measures depends upon early communication. Suspicion of any association between cases should prompt contact with the Health Protection Agency. 1. 4 IMMUNISATION COSHH requires that if a risk assessment shows there to be a risk of exposure to biological agents for which vaccines exist, then these should be offered if the employee is not already immune. In practice, with Social Care Services, this generally amounts to care staff within the Mental Health and Learning Disabilities Services being offered Hepatitis B vaccination. Care home managers, after assessing risks, may also offer ‘flu vaccination to staff and individual cases may indicate the need for immunisation in certain circumstances. The pros and cons of immunisation/non-immunisation should be explained when making the offer of immunisation. The Health Safety at Work Act 1974 requires that employees are not charged for protective measures such as immunisation. A few GPs will make vaccinations available free to Social Care workers but they are not obliged to do so and can charge at their discretion. Departmental funding for the provision of vaccine, through Occupational Health, is restricted and so it is vital that only those to whom it is essential to provide immunisation are offered this service. The majority of staff will have received immunisation from childhood and have received the appropriate booster doses e. g. Tetanus, Rubella, Measles and Polio. However, it is important for the immunisation state of staff to be checked e. g. women of childbearing age should be protected against Rubella. Good practice and common sense should indicate that the immunisation state of staff is checked and appropriate action taken. If there is a potential risk of infection, change of work rotas or areas of responsibility can sometimes avoid the risk of contamination. Vaccination is not always the only course of action and in some cases staff may not agree to be vaccinated. 1. 4. 1 IMMUNISATION SCHEDULE Vaccine Age Notes D/T/P and Hib Polio 1st dose at 2 months 2nd dose at 3 months 3rd dose at 4 months Primary Course Measles / Mumps / Rubella (MMR) 12 – 15 months Can be given at any age over 12 months Booster DT and Polio, MMR second dose 3 – 5 years Three years after completion of primary course BCG 10 – 14 years or infancy Only offered to certain high risk groups after an initial risk assessment Booster Tetanus, Diphtheria and Polio 13 – 18 years Children should therefore have received the following vaccines: By 6 months:3 doses of DTP, Hib and Polio By 15 months:Measles / Mumps / Rubella By school entry:4th DT and Polio; second dose of Measles / Mumps / Rubella Between 10 14 years:BCG (certain high risk groups only) Before leaving school:5th Polio and Tetanus Diphtheria (Td) Adults should receive the following vaccines: Women sero-negative Rubella For Rubella: Previously un-immunisedPolio, Tetanus, Diphtheria Individuals: Individuals in high Hepatitis B, Hepatitis A, Influenza risk groups:Pneumonococcal vaccine 1. 5 EXCLUSION FROM WORK The following table gives advice on the minimum period of exclusions from work for staff members suffering from infectious disease (cases) or in contact with a case of infection in their own homes (home contacts).
