I appreciate your concern over the problem and thank you for the question. First of all I would like you to know more about Chlamydia. It issexually transmitted infections that are transmitted if a person has unprotected sex with an infected person. It is also difficult to be treated. If the disease is not treated then a person is liable to have serious health problems. Therefore anyone who is infected from this problem must get the best treatment possible. The symptoms of the problem can be seen on the genitals of an individual and it can be seen on the internet to have an awareness of the problem. Coming to the treatment of the problem, azithromycin is a good medication for this problem. Depending on your problem, the doctor may ask you to have the medication once or may also give a prescription to take the medication multiple numbers of times. Coming to your question regarding the lifetime of the infection then I would like to say that in maximum number of cases the infection is cured in a period of 2 weeks. I would suggest you to not to get involved in any sexual activity. It is also recommended that both the partners take the proper treatment even if a partner does not show the symptoms of the problem. This is so because in the other case a person can get re-infected by the problem as this is a complete possibility. I would also recommend you to have safe sex always because it is the major cause of acquiring sexually transmitted infections. Hope you recover soon, all the best.
