<s>[INST] My sister is in hospital with pneumonia, and ive just got the message from family who visited last night that she may have the Strep Milleri virus. My question is.... which way round is this? Does she has Strep Milleri as a result of pneumonia or has she got pneumonia because she had the Strep virus? thank you [/INST] Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. No, Streptococcus Miller is not the virus, but it is bacteria. It Grams positive cocaine infection caused by these bacteria is pneumonia. Viral infection may be primary agent of infection, but chances of pneumonia is caused by Streptococcus Miller is more. I advise you to get bacteria sensitivity done. And take the Chat Doctor.   </s>
