262 the United States, Peru and Togo). Scientists are investigating the causes. The risk of death from yellow fever is far greater than the risks related to the vaccine. People who should not be vaccinated include: • children aged less than 9 months for routine immunization (or less than 6 months during an epidemic); • pregnant women – except during a yellow fever outbreak when the risk of infection is high; • people with severe allergies to egg protein; and • people with severe immunodeficiency due to symptomatic HIV/AIDS or other causes, or in the presence of a thymus disorder. Travelers, particularly those arriving to Asia from Africa or Latin America must have a certificate of yellow fever vaccination. If there are medical grounds for not getting vaccinated, International Health Regulations state that this must be certified by the appropriate authorities. 2. Mosquito control In some situations, mosquito control is vital until vaccination takes effect. The risk of yellow fever transmission in urban areas can be reduced by eliminating potential mosquito breeding sites and applying insecticides to water where they develop in their earliest stages. Application of spray insecticides to kill adult mosquitoes during urban epidemics, combined with emergency vaccination campaigns, can reduce or halt yellow fever transmission, “buying time” for vaccinated populations to build immunity. Historically, mosquito control campaigns successfully eliminated Aedes aegypti, the urban yellow fever vector, from most mainland countries of central and South America. However, this mosquito species has re-colonized urban areas in the region and poses a renewed risk of urban yellow fever. Mosquito control programmes targeting wild mosquitoes in forested areas are not practical for preventing jungle (or sylvatic) yellow fever transmission. 3. Epidemic preparedness and response Prompt detection of yellow fever and rapid response through emergency vaccination campaigns are essential for controlling outbreaks. However, underreporting is a concern – the true number of cases is estimated to be 10 to 250 times what is now being reported. WHO recommends that every at-risk country have at least one national laboratory where basic yellow fever blood tests can be performed. One confirmed case of yellow fever in an unvaccinated population should be considered an outbreak, and a confirmed case in any context must be fully investigated, particularly in any area where most of the population has been vaccinated. Investigation teams must assess and respond to the WHO-Facts Sheet September 2011 outbreak with both emergency measures and longerterm immunization plans.

DISABILITY AND HEALTH The International Classification of Functioning, Disability and Health (ICF) defines disability as an umbrella term for impairments, activity limitations and participation restrictions. Disability is the interaction between individuals with a health condition (e.g. cerebral palsy, Down syndrome and depression) and personal and environmental factors (e.g. negative attitudes, inaccessible transportation and public buildings, and limited social supports). Over a billion people are estimated to live with some form of disability. This corresponds to about 15% of the world’s population. Between 110 million (2.2%) and 190 million (3.8%) people, 15 years and older, have significant difficulties in functioning. Furthermore, the rates of disability are increasing in part due to ageing populations and an increase in chronic health conditions. KEY FACTS • Over a billion people, about 15% of the world’s population, have some form of disability. • Between 110 million and 190 million people have significant difficulties in functioning. • Rates of disability are increasing due to population ageing and increases in chronic health conditions, among other causes. • People with disabilities have less access to health care services and therefore, experience unmet health care needs. Disability is extremely diverse. While some health conditions associated with disability result in poor health and extensive health care needs, others do not. However, all people with disabilities have the same general health care needs as everyone else, and therefore, need access to mainstream health care services. Article 25 of the UN Convention on the Rights of Persons with Disabilities (CRPD) reinforces the right of persons with disabilities to attain the highest standard of health care, without discrimination. Unmet needs for health care People with disabilities report seeking more health care than people without disabilities and have greater unmet needs. For example, a recent survey of people with serious mental disorders, showed that between 35% and 50% of people in developed countries, and between 76% and 85% in developing countries, received no treatment in the year prior to the study.
September 2011 KUWAIT MEDICAL JOURNAL 263 Health promotion and prevention activities seldom target people with disabilities. For example women with disabilities receive less screening for breast and cervical cancer than women without disabilities. People with intellectual impairments and diabetes are less likely to have their weight checked. Adolescents and adults with disabilities are more likely to be excluded from sex education programmes. How are the lives of people with disabilities affected? People with disabilities are particularly vulnerable to deficiencies in health care services. Depending on the group and setting, persons with disabilities may experience greater vulnerability to secondary conditions, co-morbid conditions, age-related conditions, engaging in health risk behaviors and higher rates of premature death. Secondary conditions Secondary conditions occur in addition to (and are related to) a primary health condition, and are both predictable and therefore, preventable. Examples include pressure ulcers, urinary tract infections, osteoporosis and pain. Co-morbid conditions Co-morbid conditions occur in addition to (and are unrelated to) a primary health condition associated with disability. For example the prevalence of diabetes in people with schizophrenia is around 15% compared to a rate of 2 - 3% for the general population. Age-related conditions The ageing process for some groups of people with disabilities begins earlier than usual. For example some people with developmental disabilities show signs of premature ageing in their 40s and 50s. Engaging in health risk behaviours Some studies have indicated that people with disabilities have higher rates of risky behaviours such as smoking, poor diet and physical inactivity. Higher rates of premature death Mortality rates for people with disabilities vary depending on the health condition. However, an investigation in the United Kingdom found that people with mental health disorders and intellectual impairments had a lower life expectancy. BARRIERS TO HEALTH CARE People with disabilities encounter a range of barriers when they attempt to access health care including the following. Prohibitive costs Affordability of health services and transportation are two main reasons why people with disabilities do not receive needed health care in low-income countries: 32 - 33% of non-disabled people are unable to afford health care compared to 51 - 53% of people with disabilities. Limited availability of services The lack of appropriate services for people with disabilities is a significant barrier to health care. For example, research in Uttar Pradesh and Tamil Nadu states of India found that after the cost, the lack of services in the area was the second most significant barrier to using health facilities. Physical barriers Uneven access to buildings (hospitals, health centres), inaccessible medical equipment, poor signage, narrow doorways, internal steps, inadequate bathroom facilities, and inaccessible parking areas create barriers to health care facilities. For example, women with mobility difficulties are often unable to access breast and cervical cancer screening because examination tables are not height-adjustable and mammography equipment only accommodates women who are able to stand. Inadequate skills and knowledge of health workers People with disabilities were more than twice as likely to report finding health care provider skills inadequate to meet their needs, four times more likely to report being treated badly and nearly three times more likely to report being denied care. ADDRESSING BARRIERS TO HEALTH CARE Governments can improve health outcomes for people with disabilities by improving access to quality, affordable health care services, which make the best use of available resources. As several factors interact to inhibit access to health care, reforms in all the interacting components of the health care system are required. Policy and legislation Assess existing policies and services, identify priorities to reduce health inequalities and plan improvements for access and inclusion. Make changes to comply with the CRPD. Establish health care standards related to care of persons with disabilities with enforcement mechanisms. Financing Where private health insurance dominates health care financing, ensure that people with disabilities are
