(CNN)-- Daniel and Davy Macias spent 18 months being very cautious about Covid-19.
They wiped down surfaces, showered after work and even had their groceries delivered, but that didn't stop them from contracting the virus.
Davy Macias, a Southern California labor and delivery nurse, was seven months pregnant with her fifth child in early August when she was hospitalized with Covid-19. Daniel Macias also contracted the virus.
