It is important to bear in mind that pregnancy related pathologies such as chorioamnionitis, severe urinary tract infections, group A and B streptococcus infections and even malaria may present with similar symptoms. Careful clinical assessment is of vital importance in order not to miss an important infection. The patient needs to be carefully monitored with the modified early warning scores, taking into account the pregnancy. Complications of obstetric problems such as pre-eclampsia, venous thromboembolism and pulmonary embolism have also to be excluded.
