A 15-year-old boy died while transmission of the virus was over in the capital of Liberia. His mother had probably had the disease in 2014 before healing. This case shows that outbreaks of infection may reappear.
The Ebola virus may become latent in a patient that was thought to be cured and resurface to infect other people, concluded researchers cited by the review The Lancet Infectious Diseases Tuesday, July 24. The authors of the study therefore call for "close surveillance" of new cases.
The enigma was the origin of the contamination of a 15-year-old who had traveled to the hospital in Monrovia in November 2015, when transmission did not seem to be happening in the Liberian capital. He died of haemorrhagic fever four days later. The infectious investigation showed that her 33-year-old mother had most likely had the disease in July 2014. She had apparently recovered from it without treatment or consultation, resulting in miscarriage only.
Transmission seems to be husband, who reported to the hospital the same day as two of his children in 2015. This man survived, along with his youngest son, aged 8.
This mother "had a viral persistence or a recurrence of the disease, and transmitted the virus to other members of his family a year later" write the researchers. The virus "may have re-emerged in a woman a year after she survived an acute Ebola infection, potentially causing the infection of her husband and two of their sons" still summarize
Scientists already knew about the transmission of the virus by sperm by seemingly cured men. The question remains of the other bodily fluids that could transmit the virus. "We do not have a clear indication of the mode of transmission of the mother to her husband. (…) Most likely, the transmission between family members took place during a close physical interaction" specified The researchers
This case shows that outbreaks of infection may reappear. "Despite the current absence of active transmission chains of Ebola virus in West Africa, its persistence could cause continued risk of resurgence of cases and have the potential for a large-scale epidemic for lack of to be detected quickly and controlled " badures a signatory of the study, Emily Kainne Dokubo, of the Center for Disease Control and Prevention American (CDC).
