There were 222 (45.8%) early deaths within 42 days of birth (MMR of 8.0 per 100 000; 95% CI 7.0–9.2), and 263 (54.2%) late deaths from 43 to 365 days after birth (MMR 9.5 per 100 000; 95% CI 8.4–10.7).

However, treatment for BV is limited to antibiotics and half of the women treated experience recurrence within a year. THRIVE (The Study of Host-Bacterial Relationships and Immune Function in Different Vaginal Environments) is a prospective study in Winnipeg, Manitoba, Canada, which is designed to capture the daily variation of the microbiome and host mucosal immunity during treatment.
