According to a new study published in the journal Epidemiology and Infection, solar radiation may be inversely correlated with the incidence and severity of tuberculosis (TB).
Researchers examined TB incidence data, hospital admissions and mortality rates in Chile from 2001-2011. They found that over this time span, 26,691 new TB cases were registered.
After analyzing the data from these cases, the researchers discovered the solar radiation was inversely associated with the development of TB (p = 0.007), hospital admission rate (p = 0.002) and mortality rate (p = 0.002).
The researchers concluded:
“In summary, we found that regional solar radiation in Chile is inversely and independently associated with incidence and severity of clinical TB, and thereby supports a potential pathogenic role of VD deficiency in TB pathogenesis.”
