Recent guidance from the Royal College of Obstetricians and Gynaecologists and the Royal College of Midwives states that:
Women of a Black, Asian and minority ethnic background should be advised that they may be at higher risk of complications of COVID-19 and to seek advice without delay if they are concerned about their health.
The West Yorkshire and Harrogate Local Maternity System (LMS) has created a number of new films in community languages, delivered by clinicians, that aim to raise awareness among pregnant BAME women about risk factors, signs and symptoms of coronavirus infection and how to protect themselves.
NHS England also has some coronavirus-specific materials which you can find here. These are also available in community languages. Additional information for pregnant women about coronavirus and pregnancy is also available from the Royal College of Obstetricians and Gynaecologists and Royal College of Midwives.
