Difference Between Chlamydia and Herpes


Sexually transmitted infections (STIs) are a common concern for sexually active individuals. Among the various types of STIs, Chlamydia and Herpes are two of the most frequently reported. Though both of these infections can be transmitted through sexual contact, they are caused by different microorganisms and exhibit distinct symptoms. This essay aims to describe the difference between Chlamydia and Herpes in detail.

What is Chlamydia?

Chlamydia infections are either respiratory (caused by C. pneumoniae), or genital (caused by C. trachomatis). In either type of infection, pain and inflammation result in the area of infection, and both infections can be spread to other people.

Symptoms and complications − C. trachomatis causes symptoms such as pain and discharge and itching in the genital area. C. pneumonia causes a runny nose, cough, and fever. Complications that can result from C. trachomatis include pelvic inflammatory disease in women and inflammation of the testes in men. C. pneumoniae can in rare cases, lead to a worsening of asthma symptoms, infection of the heart muscle and the brain. It can lead to death in a few rare cases.

Diagnosis − A molecular test looking for the DNA of the Chlamydia can provide a positive diagnosis of the presence of the species. Physical symptoms may be suggestive of a particular infection, but the molecular test can give certainty as to the identity of the causative organism.

Risk factors and treatment: The C. pneumoniae is caught by being around people who are sick with the disease, so if you are in a crowded area where there are sick individuals. The old and very young are at increased risk of this infection. The C. trachomatis is spread through sex, so the more partners a person has the greater the risk of contracting this STD. The antibiotic doxycycline is often used to treat chlamydial infections.

What is Herpes?

Herpes is a viral infection caused by the herpes simplex virus (HSV). There are two types of HSV, HSV-1 and HSV-2. HSV-1 is typically associated with oral herpes, which causes cold sores around the mouth. HSV-2 is usually associated with genital herpes, which causes blisters or sores around the genitals and rectum.

Symptoms − The symptoms of herpes can vary depending on the type of HSV and the location of the infection. Some people infected with herpes may not experience any symptoms, while others may have −

  • Painful blisters or sores around the genitals or rectum

  • Flu-like symptoms, such as fever and body aches

  • Itching or tingling around the infected area

  • Painful urination

  • Headache and fatigue

  • Testing and Treatment:

Herpes can be diagnosed through a physical examination and a blood test that detects the presence of antibodies against the virus. Currently, there is no cure for herpes. However, antiviral medications can help to reduce the severity and frequency of outbreaks. These medications are usually prescribed for a period of 7 to 10 days during an outbreak.

Differences: Chlamydia and Herpes

Causative Agent − Chlamydia is caused by a bacterial infection, while Herpes is caused by a viral infection.

Transmission − Both infections are sexually transmitted, but Chlamydia can also be transmitted from mother to baby during childbirth.

Symptoms − The symptoms of Chlamydia may include painful urination, abnormal vaginal discharge, and pain during sexual intercourse, while Herpes can cause painful blisters or sores around the genitals and rectum.

Diagnosis − Chlamydia can be diagnosed through a simple urine test or a swab test, while Herpes can be diagnosed through a physical examination and a blood test.

Treatment − Chlamydia can be treated with antibiotics, while Herpes has no cure. Antiviral medications can help to manage the symptoms and reduce the frequency and severity of outbreaks.

Definition

Chlamydia is a common, sexually transmitted infection that may not show any symptoms. It is present in infected semen and vaginal fluids.

Herpes is a common sexually transmitted infection (STI) marked by sores and genital pain. It is spread through skin contact during anal, vaginal or oral sex.

Symptoms

  • Burning sensation while peeing

  • Pain during sexual intercourse

  • Tender or swollen testicles

  • Bleeding and spotting between monthly periods

  • Strong smell in the vaginal discharge

  • Abnormal (yellowish) vaginal discharge in women

  • Lower belly pain.

  • Pus or a watery/milky discharge from the penis in men

  • Red, cracked, or raw areas around the genitals without tingling, itching, or pain

  • Irritation and Itching around the anal region or the genitals

  • Pain in the back

  • Flu-like symptoms, including fatigue, fever, and swollen lymph nodes

  • Headaches

  • Tiny blisters that cause painful sores after breaking open. These usually can be seen on rectal areas, thighs, buttocks and on or around the genitals (penis or vagina). Rarely, some blisters can occur inside the urethra — the tube urine travels through on its way out of your body.

  • Pain and difficulty while peeing over the sores – a typical problem especially in women.

Causes

Chlamydia is caused by unprotected oral, vaginal or anal sex with a person. Genital contact also passes on chlamydia. As the infection shows no symptoms in at least seventy percent of the carriers, individuals carrying the infection could pass it on to their sexual partners without any knowledge of them being infected.

The infection is caused by the bacteria Chlamydia trachomatis (C.trachomatis)

The herpes simplex virus, also termed as HSV, is an infection that is a cause of herpes. The infection affects various parts of the body, like the genitals or mouth. There are 2 types of the HSV.

  • HSV-1- This virus causes oral herpes through sores on the skin, oral secretions, kissing, sharing lip balm,sharing toothbrushes or eating from the same utensils and symptoms are blisters around the face and mouth and cold sores.

  • HSV-2 – This virus causes genital herpes a person gets infected with herpes type 2 infection through sexual contact with someone who has a genital HSV-2 infection.

Diagnosis

Diagnosis and screening of chlamydia is relatively simple. Some tests include

  • A urine test – Urine sample is tested in the lab to detect presence of this STI.

  • A swab – In case of females, the doctor takes a swab of the cervix discharge for antigen testing or culture testing. This is done by means of routine Pap test. Some females prefer to swab their vaginas themselves, which has been confirmed to be as diagnostic as doctor-obtained swabs.

  • Viral culture test – A tissue from a sore is taken for examination in the laboratory.

  • Polymerase chain reaction (PCR) test – A tissue from a sore or spinal fluid or blood sample is taken and DNA is copied. The DNA is tested to determine the infection by HSV.

  • Blood test – Blood sample is tested to determine the presence of HSV antibodies for detecting a past herpes infection.

Treatment

Oral antibiotics, usually azithromycin (Zithromax) or doxycycline. Women with severe infection may need intravenous antibiotics (medicine given through a vein), hospitalization, and pain medicine.

Patients’ need to be re-tested after 3 months once after taking antibiotics, to ensure the infection is cured. Do not have sexual intercourse until you and your partner both are free from this infectious disease.

Treatment may include antiviral medications such as valaciclovir or Acyclovir. For pain and easing the herpes symptoms – aspirin, acetaminophen, or ibuprofen, can be helpful. Doctors even recommend soaking the affected area in warm water.

Conclusion

Chlamydia is a common sexually transmitted infection (STI) that may not show any symptoms, while Herpes is a common STI marked by sores and genital pain.
