My daughter stayed a weekend with a friend whose sister has some kind of "contagious terminal illness" called something like seadiff or something.  She says one of the symptoms is diareha and vomitting.  Now my daughter is vomitting all day and night.  She is worried that she may have caught this disease.  Do you know what disease this is and how worried should I be?
Hello, I understand your concern. I am Chat Doctor, infectious disease specialist, answering your concern. I think you are speaking of the C. difficile infection. This type of infection never occurs to general population. It can occur to those people having prolong antibiotic therapy, prolonged hospitalization and immunosuppression. Yes it can be contagious but only to the above-mentioned category. But you should diagnose your daughter first to give them treatment. I advice you to test for toxins produced by the C.difficile. It is treatable and has no reason to worry. Once it is diagnosed you can take clindamycin under your doctors' guidance. It will clear up the infection in your daughter. Please adopt good handwashing practice for whole family members. It will create a barrier for all the peoples. I will be happy to answer your further concern you can contact me here, or you can contact me on bit.ly/ Chat Doctor.  You can hit thank you button if you are helped. Thank you, ChatDoctor
