Mothers with chikungunya do not pass the infection on to their offspring during pregnancy. However, there have been reported occurrences of mother-to-child transmission when the mother develops a fever in the days preceding or during delivery. A caesarean section does not prevent transmission. As a result, pregnant women with chikungunya are in danger of transmitting the disease to their babies and should visit a doctor. Chikungunya is not spread through breast milk.
