While this is often the most distinguishing symptom of a virus, you must rule out the possibility that Thrips have caused these streaks. If your African Violet exhibits either of these symptoms, it may have a virus. If you have ruled out other possible causes of the symptoms, but you are still unsure whether or not your Violet has a virus, contact your local botanical garden or agricultural extension office. If they agree to examine the plant, be sure to seal the Violet in a plastic bag in order to prevent the spread of the virus. Other Symptoms Leaves are deformed or twisted .
