| 1 |  | Figure 1-22 Number of illness cases in private industry by type of illness, 1972-2001. Since 1972, BLS data illustrate significant variation in the number of reported illness cases. From 1972 to 1982, the number of illness cases declined gradually from 210,500 to 105,600. This number increased and peaked sharply in 1994 at 514,700 cases. The number of cases declined steadily to 333,800 in 2001. Disorders associated with repeated trauma declined for 7 consecutive years dating from 1995. About 216,400 cases were reported in 2001, compared with a high of 332,100 cases in 1994. (Source: BLS [2002b].)

Since first reporting illness category rates in 1984, BLS has tracked the steep increase in overall illness rates that began in the mid-1980s and peaked in 1994. The overall pattern reflects the trends for disorders associated with repeated trauma. (Source: BLS [2002b].)

Rates for other categories of illness were smaller than for disorders associated with repeated trauma. These diseases and disorders represent approximately one-third of all reported occupational illnesses. Skin diseases or disorders have consistently accounted for 12%-14% of all occupational illness cases, with rates ranging from 8.2 to 4.3 per 10,000 full-time workers between 1992 and 2001.

The annual number of hypersensitivity pneumonitis deaths generally increased during 1979-1999, from fewer than 15 per year in 1979 to 57 in 1999. Hypersensitivity pneumonitis was designated as the underlying cause of death in at least half of deaths associated with hypersensitivity pneumonitis for every year except 1982.

During 1968-1999, deaths from asbestosis increased over time, whereas deaths from CWP decreased. Deaths from all pneumoconioses are shown at the top of each stacked bar. The bars slightly overstate the numbers because a small fraction of deaths was associated with more than one type of pneumoconiosis. (Note: Byssinosis data were not available before 1979. Also note that the sum of deaths for various types of pneumoconiosis (N=123,091) exceeds the total number of pneumoconiosis deaths (N=121,982) because some decedents had more than one type of pneumoconiosis recorded on their death certificates.)
