Hi, I think your biggest concern should be about her getting bacterial pneumonia. It might be just a virus for now, but a virus can lead to bacterial pneumonia. If she can't see a doctor because of cost or any other reason, she must go anyway for antibiotics if it turns into a bacterial pneumonia.
How high is her fever? Does she have these symptoms?
High fever up to 105 F
Coughing out greenish, yellow, or bloody mucus
Chills that make you shake
Feeling like you can’t catch your breath, especially when you move around a lot
Feeling very tired
Sharp or stabby chest pain, especially when you cough or take a deep breath
Sweating a lot
Fast breathing and heartbeat
Lips and fingernails turning blue
Confusion, especially if you’re older
-4C is pretty low (25F). Put her under blankets, laying on an electric heating pad to keep her warm.
Sravan, there is an Emergency Department nurse named 'uomeasmile' that answers questions here. I've written to her to ask if she can look at your post, but I don't have any idea when she is around or not.
Please keep watching to see if she replies.
Hello. I am sorry your girlfriend is ill. Can you tell us a little more about her cough? Is she coughing anything up (a productive or moist cough)? Is she wheezing with the cough? Flu season is upon us. Any viral illness can lead to bronchitis or pneumonia. Depending on your geographical location my other concern would be tuberculosis. When a person develops active TB disease, the symptoms (such as cough, fever, night sweats, or weight loss) may be mild for many months. This can lead to delays in seeking care, and results in transmission of the bacteria to others. If her cough and fever persist she needs to see a medical provider. In the meantime make sure she stays well hydrated and gets plenty of rest. Take common sense precautions such as frequent handwashing to prevent the spread of the illness. If you can answer Ken's list of symptoms or tell us more about her cough it might help narrow down the possibilities.
