the place is stable politically , but insecurity from robbers and thugs is rampant . It more common in Nairobi and major towns. Rurals areas are somwhat safe but i would still urge caution and for her to keep a low profile.
Kenyans are generally friendly and will welcome her. I hope she knows a group that will help her negotiate the country. I think she is well covered as a missionary . there are never problems for this group, they have a good name and they help people. No one wnats to cut the hand that feeds them.
Currrency. she should not have any notes of 1996 and preceding years. some banks refuse them while others charge a higher rate than normal. Forex bureaus offer the best rates. There are many in nairobi especially laong wabera st , mama Ngina st and Jomo kenyatta avenue

Dressing; Long skirts , loose trousers, cleavege coverd etc, . I mention this due to the fact that there are areas where women are harrassed by men due to their dressing mode. It does not happen all over the country , but is a advisable to have afew of the suggested oufits. in addition, long sleeves/ skirts curtail bugs as well , and protect the skin from the sun. DEc to March is the hottest season.. Cotton fabric and easy to wash and wear works excellently. As a rule of thumb Kenyans are very conservative dressers compared to americans, although in Nairobi you find people dressed in all from of outfits.
hope this helps
