- Unsafe Sexual Practices
Unprotected or unsafe sexual practices can dramatically increase your risks of developing a sexually transmitted disease (STD). Many of these STDs have a number of unpleasant side effects and can lead to severe health complications. [epigee.org]

Painful inguinal lymphadenopathy is characteristic of chancroid regardless of the site of the lesion; however, such a presentation occurs in only 40% of cases. [hivguidelines.org]
Etiology Clinical features Incubation period : typically 4–10 days Clinical features Very painful genital ulcers Deep, small ( 10–20 mm in diameter), well-demarcated lesions with a grayish necrotic base Painful inguinal lymphadenopathy An asymptomatic [amboss.com]
Genital trauma is usually suspected by history and less prominent inguinal lymphadenopathy than seen in chanchroid. [clinicaladvisor.com]
There were two major genital ulcers, one of which was a painful ulcer in the left labia major and the other was a painless ulcer in the cervix uteri; she was also found upon examination to have bilateral inguinal lymphadenopathy. [dx.doi.org]
Lymphadenopathy Unilateral or bilateral inguinal lymphadenopathy develops in approximately 50% of untreated patients, beginning approximately 1 week after the onset of the initial lesion. [dartmouth.edu]

Work up consists of a detailed history and physical examination.
- Gram staining: Gram staining may be done to check for the organism involved.
- PCR: A Polymerase Chain Reaction test maybe done for more accurate results.
- C/S: Culture and sensitivity of either blood samples, pus or swab samples may be done for accurate results.
- Biopsy: Biopsy may be carried out and 3 distinct histologic zones may be seen.
If the test results come positive, treatment is immediately started.
Other STDs are also checked.

CDC recommends antibiotic therapy from 1 of 4 equally efficacious agents, as follows :
- Ceftriaxone (drug of choice in pregnant females)
- Erythromycin base
If abscess is present, pus should be aspirated and drained.
Chancroid has an excellent prognosis. If treated with proper antibiotics, such as cephalosporins, or macrolides (azithromycin), the disease shows a positive response. Symptoms regress in just a few days of antibiotic treatment and completely disappear after some time. A 3-antibiotic regime is given to ensure reinfection may not occur as well as any other STDs, like Chlamydia, may also be treated if present.
Chancroid is an acute, sexually transmitted, ulcerative infection caused by Hemophilus ducreyi . H. ducreyi is a gram-negative streptobacillus that may enter the body by piercing through the skin during sexual intercourse. Once the bacterium enters the genitals, it goes through an incubation period of a few days and then results in the development of soft chancre.
Chancroid is relatively uncommon in the United States, with only 24 cases reported in 2010. It is prevalent in Africa, however, and it is thought to be the most common cause of genital ulcers in Kenya, Gambia and Zimbabwe .
Studies reveal that men are affected more than females.
In the US, girls aged between 15-19 have the highest prevalence while men aged between 20 and 24 are the most commonly affected. Uncircumcised males are more prone to contract this disease.
Chancroid shows a clear predilection in non-white people.
Incubation period is of about 1-8 days, after which multiple, irregular tender ulcers may develop . In males, the primary lesion is usually on the penis; in females most lesions occur in the vagina or the periurethral area .
Once the incubation period is complete, one or more papules may appear, which then turn into soft, painful pustules. These slowly progress into ulcers by undergoing central necrosis. These ulcers are very painful and may easily bleed. They have sharply demarcated boundaries and a yellowish-grey base. Size ranges from 0.8 inch to 2 inches.
The regional lymph nodes, particularly in the inguinal region, become enlarged and tender in about 50% of cases within 1 to 2 weeks of the primary inoculation .
Chancroid, like all other STDs, is easily preventable. By taking appropriate safety measures like using protection such as latex condoms during intercourse, may prevent transmission of the disease. Other measures include avoiding multiple sexual partners, and being tested regularly for STDs.
Chancroid, or soft chancre is an acute sexually transmitted disease (STD) caused by Hemophilus ducreyi. It is common in tropical areas of the world and is endemic in parts of Africa and Asia .
Different from syphilis (hard chancre) in causative agent, prevalence and presentation, chancroid (soft chancre) is a relatively uncommon sexually transmitted disease. It rarely causes any complications, and prognosis is excellent.
Cause and Symptoms
Chancroid is caused by having unprotected sex with an infected person. During sexual contact, the bacteria may enter through the genital skin and cause an infection which results in symptoms such as swollen genitals, painful pustules and/or ulcers and pain or burning sensation during urination and intercourse.
Treatment is antibiotics and a sex-free period till the disease is cured.
It can be easily prevented by taking the right precautionary measures like using latex condoms during intercourse, screening and testing for STDs once a year and not having multiple sexual partners.
