Hi, dear I have gone through your question. I can understand your concern. Your platelet count is low. There are many causes of low platelet count. Even simple viral infection can leads to this. Malaria, dengue, viral fever are some of the cause. Your platelet count is increasing so no need to worry. You should repeat your count after a week. If it becomes normal then no any further investigations are required. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
