Can the doctors name the major symptoms of this disease? The signs need up to 3 weeks to develop and pop up. The main symptoms occur and are present for about one week. Those are reddish rash, which basically covers the patient’s face, moving to other parts sooner or later; a fever less than 102°F; swelling sensation in the lymph nodes; dizziness; ache in the muscles, and tired eyes, colored in red. The baby or child may feel really bad once Rubella symptoms appear. Pay attention to these symptoms in case you or your wife is pregnant.
