Ten-month-old Sebastian Romero was born without an immune system due to a rare genetic disorder called severe combined immunodeficiency (SCID) and must live in his sanitized home with no other contact in order to not be infected.
SCID means that his body does not have enough immune-fighting cells, T and B cells, to fight off an infection, so something as simple as the common cold could immediately send him to the hospital and even kill him. According to the US Department of Health and Human Services, a normal T cell count should be between 500 and 1,200 per cubic millimeter of blood, but Sebastian had none.
Bianca Romero, that baby's mother said she lived in total isolation for the first three months of his life. 'We would FaceTime and that's the only way I would see the kids. Sometimes they would crack the door and put facemasks on,' she said.
Fortunately, the infant received a bone marrow transplant in May that has helped rebuild his immune system.
The mother-of-three told Daily Mail Online that she is not taking any risks and he will be kept isolated in their sanitized Texas home until his cell count is high enough to fight off infection. The family-of-five take precautions before entering the home, they all shower and change clothes immediately before going inside.
