I'm supposed to travel to a country with widespread malaria for work; normally it's not a problem, there are plenty of prophylactic drugs and I know how to cover up. However, I've just looked up all of those drugs and none of them seem terribly safe in pregnancy. One is category B, but it has been shown to cause fetal harm in animal studies and I'd rather steer clear.
Edit: I've basically decided not to go.
However, I haven't yet told anyone at work I'm pregnant, being that I'm only 8w3d and things could still go wrong; Do you have any advice on how to handle the situation, i.e. how to avoid travel without telling my boss about the pregnancy?
Re: Advice on work situation
Personally I don't think at this point you have any obligation to bring up your pregnancy status as part of your contract conversation. It's the norm not to tell employers until around 12-13 weeks and even longer is ok. I'd be very irritated if an employee waited until the legal limit but there's some flexibility. Also my suggestion would be to get as much of your conversations re your contract in written form as possible. For example sending an email following your conversation to confirm her positive statements or intentions regarding your contract. Then if she denies to extend after you've announced you will have something more concrete to bring to a higher manager or HR department. Even writing your takeaways down immediately after and sending to yourself (so there's a timestamp) could be helpful.
Another option is to consult with an infectious disease doctor about the risk to not taking malaria pills while you are there. Depending on the length of your trip, where you are staying, etc your risk of being bitten might be low. Always a difficult balance between taking a class b drug vs contracting an illness that will require taking something for a longer period of time, but definitely a conversation that could be had should you end out needing to go even though you don't want to.
