70. The gross income of a worker who suffers a recurrence, a relapse or an aggravation is the greater of the income he derives from the employment he holds when he suffers the recurrence, relapse or aggravation and the gross income used as a basis for computing his former indemnity.
For the purposes of the application of the first paragraph, where the recurrence, relapse or aggravation occurs more than one year after the worker has become disabled, the gross income used for computing his former indemnity is revalorized.
