STI (Sexually Transmitted Infection)/ STD (Sexually Transmitted Disease) refer to infections or diseases that spread primarily through sexual contact. The main difference is that STI refers to the early stage, where an infection may not show symptoms, while STD implies that symptoms have developed and the infection has progressed to a disease.

Causes
STIs and STDs are caused by bacteria, viruses, or parasites. Common causes include:
Bacteria (like chlamydia, gonorrhea, syphilis)
Viruses (like HPV, herpes, HIV)
Parasites (like trichomoniasis)
These infections spread through unprotected sexual activity, shared needles, and sometimes even from mother to baby during childbirth.

Symptoms
While some STIs show no symptoms initially, possible symptoms can include:
    –Unusual discharge from the genitals
    –Burning or pain during urination
    –Rashes, sores, or bumps around the genital area
    –Pelvic pain, especially in women
If left untreated, STDs can cause long-term issues like infertility, organ damage, or increased risk of other infections.

Treatment
STIs and STDs are treatable, especially when caught early:
    –Bacterial STIs can usually be treated and cured with antibiotics.
    –Viral STIs may not be curable but can be managed with medication to reduce symptoms and transmission risk.
    –Preventative care, like vaccines (for HPV and hepatitis), using protection during sexual activity, and regular testing, is key to managing and preventing STIs.
Regular check-ups and open communication with healthcare providers are essential for prevention, early detection and effective treatment.
