Furthermore, it is general experience that hemolytic streptococcic respiratory infections in children and young adults who have previously had one or more attacks of rheumatic fever cause recurrence of the disease in 40 to 50% of instances. An additional 10 years of data on the same workers were used in a follow-up study published in 2009 (6). The results showed an increased risk of death due to leukemia, particularly myeloid leukemia, among workers exposed to formaldehyde. Homes in which UFFI was installed many years ago are not likely to have high formaldehyde levels now. The Housing/Health Relationship: What Do We Know? How is the general population exposed to formaldehyde? Access scientific knowledge from anywhere. “I remember how sick she was but we never, ever had a conversation with doctors about what the future would look like and how much time we had,” says Seow. This observation led the researchers to conclude that factors other than formaldehyde exposure might have caused the increased deaths. Health risks in homes insulated with urea formaldehyde foam.
