Respondent (Claimant) was awarded workers’ compensation benefits for disability from carpal tunnel syndrome resulting from repetitive trauma to both wrists. 1 Petitioners (Employer) appealed. The circuit court and the Court of Appeals affirmed. 2 The only issue is whether a repetitive trauma injury is compensable under the South Carolina Workers’ Compensation Act. We find it is and affirm.
FACTS
Claimant worked for Employer in various capacities beginning in 1987. Each of her jobs involved the repetitive use of her hands. In the spring of 1995 she began experiencing tingling and numbness in both hands. On April 25, 1995, she was diagnosed with moderately severe carpal tunnel syndrome caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. The evidence is uncontradicted that claimant’s injury is work-related.
*170 After surgery in June 1995, Claimant’s left wrist improved temporarily but her symptoms returned within six months. Claimant’s treating doctor removed her from work beginning April 20, 1996. By May 1996, she had severe carpal tunnel syndrome in her right wrist. Surgery was recommended for her right wrist in October 1996 with no guarantee of relief from her symptoms.
Meanwhile, on July 21, 1996, Claimant filed this action claiming benefits for án on-the-job injury. Claimant was awarded temporary total benefits continuing until she reaches maximum medical improvement.
The circuit court and the Court of Appeals held a repetitive trauma injury is compensable as an “injury by accident” as provided in S.C.Code Ann. § 42-1-160 (Supp.2001).
ISSUE
Is a repetitive trauma injury compensable as an injury by accident?
DISCUSSION
Employer contends a repetitive trauma injury does not qualify as an “injury by accident” because the cause of the injury is not unexpected and the injury lacks definiteness of time. In the alternative, Employer contends injury from repetitive trauma should be compensable as an occupational disease if compensable at all.
1. Unexpectedness
Employer contends the repetitive event which causes a repetitive trauma injury is not unexpected but is part of the worker’s normal work activity. Because the event causing the injury is not unexpected, Employer argues repetitive trauma injury cannot be compensable as an injury by accident.
Under § 42-1-160, a claimant is entitled to benefits for an “injury by accident arising out of and in the course of employment.” In
Layton v. Hammond-Brown-Jennings Co.,
As we more recently stated, “in determining whether something constitutes an injury by accident the focus is not on some specific event, but rather on the injury itself.”
Stokes v. First Nat’l Bank,
Employer’s contention that the cause of the injury must be unexpected is incorrect. Under South Carolina law, if the injury itself is unexpected, it is compensable as an injury by accident.
*172 2. Definiteness of time
Employer contends the injury resulting from repetitive trauma has no definite time of occurrence and therefore it is not compensable as an injury by accident.
Definiteness of time, while relevant to proving causation, is not required to prove an injury qualifies as an injury by accident. For instance, in
Sturkie v. Ballenger Corp.,
Further, under S.C.Code Ann. § 42-1-160 (Supp.2001), a disease, which typically has a gradual onset, is compensable as an injury by accident “when it results naturally and unavoidably from the accident.” This provision indicates the legislature intended an accident to be compensable under the Act, even where the effects of the accident develop gradually. The fact that a repetitive trauma injury is disease-hke in its gradual onset does not preclude it from coverage as an injury by accident.
Here, it is uncontested that Claimant’s carpal tunnel syndrome was caused by her work activities. 4 The lack of a definite time of injury is therefore not dispositive.
3. Repetitive trauma injury as occupational disease
Employer contends that if a repetitive trauma injury is compensable under the Workers’ Compensation Act, it should be compensable only as an occupational disease and not as an injury by accident. The Court of Appeals rejected this argument and followed the rationale of other courts that have focused on the commonly understood meaning of the word “disease” to conclude repetitive trauma is not an occupational
*173
disease.
See Lutrell v. Ind. Comm’n,
Whether a repetitive trauma injury is compensable either as an injury by accident or an occupational disease has not been squarely addressed by this Court.

As other courts have recognized, the difficulty in deciding this issue arises from the fact that a repetitive trauma injury has some of the characteristics of both accidental injury and occupational disease — it is the cumulative effect of repeated and distinct events that ultimately produces the disability.
See Berry v. Boeing Military Airplanes,
Further, it is not obvious that either approach is more favorable to finding coverage.
See Mauldin v. Dyna-Color/Jack Rabbit,
In South Carolina, our statute defines an occupational disease as “a disease arising out of and in the course of employment which is due to hazards in excess of those ordinarily incident to employment and is peculiar to the occupation in which the employee is engaged.” S.C.Code Ann. § 42-11-10 (1985). Unlike the North Carolina courts, however, we have not construed the definition of occupational disease so rigidly. The statute is satisfied where the claimant is able to show simply that the employment increased the risk of the disease.
See Mohasco Corp. v. Rising,
In any event, the commission found Claimant’s repetitive trauma injury was compensable as an injury by accident. We find a repetitive trauma injury meets the definition of injury by accident in that it is an unforeseen injury caused by trauma. We therefore conclude the commission’s finding is supported by substantial evidence.
See Anderson v. Baptist Med. Center,
AFFIRMED.
Notes
. Carpal tunnel syndrome may also result from one traumatic event or as a secondary effect of another condition such as diabetes or pregnancy, which is not at issue here. See The Merck Manual of Medical Information (1997).

Pee v. AVM, Inc.,
. In Hiers, we noted the policy reason for adopting such a definition: If [the injury] results from the conditions under which the work is carried on, there is no reason why it should not be held compensable. In such case, it is one of the casualties of business; and it is the purpose of the compensation statutes to place the burden of casualties upon the business and not upon the unfortunate employee.
. Employer's claim that our holding makes compensable all the effects of aging is without merit since causation must always be established. Whether there is any causal connection between employment and an injury is a question of fact for the Commission.
