The Cost of Air Pollution: Health Impacts of Road Transport
Source: Organisation for Economic Co-operation and Development

Outdoor air pollution kills more than 3 million people across the world every year, and causes health problems from asthma to heart disease for many more. This is costing societies very large amounts in terms of the value of lives lost and ill health. Based on extensive new epidemiological evidence since the 2010 Global Burden of Disease study, and OECD estimates of the Value of Statistical Life, this report provides evidence on the health impacts from air pollution and the related economic costs.

Middle East Respiratory Syndrome (MERS) is viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called MERS-CoV. Most people who have been confirmed to have MERS-CoV infection developed severe acute respiratory illness. They had fever, cough, and shortness of breath. More than 30% of these people died.

So far, all the cases have been linked to countries in the Arabian Peninsula. This virus has spread from ill people to others through close contact, such as caring for or living with an infected person. However, there is no evidence of sustained spreading in community settings.

On May 2, 2014, the first U.S. case of MERS was confirmed in a traveler from Saudi Arabia to the U.S. The traveler is considered to be fully recovered and has been released from the hospital. Public health officials have contacted healthcare workers, family members, and travelers who had close contact with the patient. At this time, none of these contacts has had evidence of being infected with MERS-CoV.

On May 11, 2014, a second U.S. imported case of MERS was confirmed in a traveler who also came to the U.S. from Saudi Arabia. This patient is currently hospitalized and doing well. People who had close contact with this patient are being contacted. The two U.S. cases are not linked.

Potentially Preventable Deaths from the Five Leading Causes of Death — United States, 2008–2010

In 2010, the top five causes of death in the United States were 1) diseases of the heart, 2) cancer, 3) chronic lower respiratory diseases, 4) cerebrovascular diseases (stroke), and 5) unintentional injuries (1). The rates of death from each cause vary greatly across the 50 states and the District of Columbia (2). An understanding of state differences in death rates for the leading causes might help state health officials establish disease prevention goals, priorities, and strategies. States with lower death rates can be used as benchmarks for setting achievable goals and calculating the number of deaths that might be prevented in states with higher rates. To determine the number of premature annual deaths for the five leading causes of death that potentially could be prevented (“potentially preventable deaths”), CDC analyzed National Vital Statistics System mortality data from 2008–2010. The number of annual potentially preventable deaths per state before age 80 years was determined by comparing the number of expected deaths (based on average death rates for the three states with the lowest rates for each cause) with the number of observed deaths. The results of this analysis indicate that, when considered separately, 91,757 deaths from diseases of the heart, 84,443 from cancer, 28,831 from chronic lower respiratory diseases, 16,973 from cerebrovascular diseases (stroke), and 36,836 from unintentional injuries potentially could be prevented each year. In addition, states in the Southeast had the highest number of potentially preventable deaths for each of the five leading causes. The findings provide disease-specific targets that states can use to measure their progress in preventing the leading causes of deaths in their populations.

The Spotlight on Senior Health: Adverse Health Outcomes of Food Insecure Older Americans research study documents the health and nutrition implications of food insecurity among seniors aged 60 and older. The study reveals that senior food insecurity is associated with lower nutrient intake and an increased risk for chronic health conditions.

Compared to food secure seniors, food insecure seniors are:

  • 60 percent more likely to experience depression
  • 53 percent more likely to report a heart attack
  • 52 percent more likely to develop asthma
  • 40 percent more likely to report an experience of congestive heart failure

In addition, Spotlight on Senior Health highlights that the senior population is particularly vulnerable to the negative health and nutrition implications of food insecurity compared to other adult age groups.

Trends in Tuberculosis — United States, 2013

Trends in Tuberculosis — United States, 2013

In 2013, a total of 9,588 new tuberculosis (TB) cases were reported in the United States, with an incidence rate of 3.0 cases per 100,000 population, a decrease of 4.2% from 2012 (1). This report summarizes provisional TB surveillance data reported to CDC in 2013. Although case counts and incidence rates continue to decline, certain populations are disproportionately affected. The TB incidence rate among foreign-born persons in 2013 was approximately 13 times greater than the incidence rate among U.S.-born persons, and the proportion of TB cases occurring in foreign-born persons continues to increase, reaching 64.6% in 2013. Racial/ethnic disparities in TB incidence persist, with TB rates among non-Hispanic Asians almost 26 times greater than among non-Hispanic whites. Four states (California, Texas, New York, and Florida), home to approximately one third of the U.S. population, accounted for approximately half the TB cases reported in 2013. The proportion of TB cases occurring in these four states increased from 49.9% in 2012 to 51.3% in 2013. Continued progress toward TB elimination in the United States will require focused TB control efforts among populations and in geographic areas with disproportionate burdens of TB.

Trends in Pediatric and Adult Hospital Stays for Asthma, 2000-2010

Asthma is a chronic disease characterized by inflammation of the airways. It restricts the passage of air into the lungs and leads to episodes of wheezing, coughing, chest tightness, and shortness of breath. Severe asthmatic episodes can close off airways completely and, in some cases, may be life-threatening.1

In 2010, approximately 7.0 million children aged 0—17 years and 18.7 million adults aged 18 years and older had a diagnosis of asthma. The prevalence of asthma in the United States has increased from 7.3 percent of the population in 2001 to 8.4 percent in 2010.2

Asthma is largely controllable with proper primary care, and the need for hospitalization can usually be prevented. However, differences in rates of hospitalization for asthma suggest that there is significant room for improvement in caring for the condition.

This Statistical Brief presents data from the Healthcare Cost and Utilization Project (HCUP) on trends in pediatric and adult inpatient hospital stays for asthma at U.S. community hospitals from 2000 through 2010. In addition, we present patient characteristics of pediatric and adult hospital stays for asthma in 2010. Differences that are noted in the text exhibit at least a 10 percent difference between estimates and are statistically significant at 0.05 or better.

Lung Cancer Incidence Trends Among Men and Women — United States, 2005–2009

Lung cancer is the leading cause of cancer death and the second most commonly diagnosed cancer (excluding skin cancer) among men and women in the United States (1,2). Although lung cancer can be caused by environmental exposures, most efforts to prevent lung cancer emphasize tobacco control because 80%–90% of lung cancers are attributed to cigarette smoking and secondhand smoke (1). One sentinel health consequence of tobacco use is lung cancer (1,2), and one way to measure the impact of tobacco control is by examining trends in lung cancer incidence rates, particularly among younger adults (3). Changes in lung cancer rates among younger adults likely reflect recent changes in risk exposure (3). To assess lung cancer incidence and trends among men and women by age group, CDC used data from the National Program of Cancer Registries (NPCR) and the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program for the period 2005–2009, the most recent data available. During the study period, lung cancer incidence decreased among men in all age groups except <35 years and decreased among women aged 35–44 years and 54–64 years. Lung cancer incidence decreased more rapidly among men than among women and more rapidly among adults aged 35–44 years than among other age groups. To further reduce lung cancer incidence in the United States, proven population-based tobacco prevention and control strategies should receive sustained attention and support (4).
