If you’re pregnant lock yourself in the house, shut the curtains and wear a facemask if you so much as put your nose outside the door… has advice to pregnant women finally gone too far? Or, given that at least six healthy women in their second and third trimesters of pregnancy are reported to be in intensive care with pandemic flu in Australia is this reasonable advice?
The difficulty is that as yet we don’t know enough about the behaviour of the new H1N1 flu virus. This lack of information creates a vacuum that gets filled with a cacophony of conflicting expert advice that gets amplified through our pervasive media systems.
The latest flurry of advice to pregnant women is at best confusing and at worst completely impractical and non evidence-based. According to guidance from the Royal College of Obstetricians and Gynaecologists (RCOG) pregnant women should avoid “unnecessary travel”. So what exactly constitutes unnecessary travel? How many pregnant women set off each morning on spurious jaunts to the seaside, frivolous journeys to work, or perhaps decide that today is the day to sample their local bus routes for kicks?
The Royal College of Midwives advise that pregnant women should “avoid crowded places when possible”. Again, I’m not quite sure how women are meant to do that. Perhaps now is the time to switch from travelling to work on the underground and finally hire a chauffeur (one that’s already had swine flu preferably) to keep you away from the virus-breathing hordes? Or, is this the perfect excuse for pregnant women to create a domestic dictatorship and sit at home loftily issuing instructions to every family member as they are committed to self-incarceration?
In Australian media reports, the president of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) is quoted as advising that pregnant women should wear masks in crowded places, especially if they also have asthma and are overweight. This is not evidence-based advice, as simple facemasks do not protect people from catching flu. Is this a matter of media misquoting or is that really what the RANZCOG advise?
The bottom line is that hand and respiratory hygiene measures are the best ways to reduce the risk of H1N1 flu in pregnancy. The conflicting messages about masks and staying at home dilute the key messages to everyone about hand washing, sneezing and disposing of tissues. So, perhaps when leaving the house, pregnant women would be better advised to take some soap or alcohol hand gel with them, rather than a facemask, and use it to clean their hands regularly.
Although, perhaps I’ve committed the ultimate sin and simply added even more conflicting advice.
