How much do you know about HIV and TP?

AIDS and Syphilis are diseases that many people have heard of, and people may know that both pose a great threat to human health. However, do you know the differences between them?

Do not worried, this article will help you distinguish them.

1. Pathogen

HIV (Human Immunodeficiency Virus) , is the culprit behind AIDS.


TP (Treponema pallidum), is a bacterium that causes syphilis.


2. Pathogenesis

AIDS, also known as acquired immunodeficiency syndrome, is caused by the HIV virus. After infecting the human body, the virus invades CD4+ T lymphocytes (a type of immune cell) in the immune system. The HIV virus gradually destroys the functions of host cells, leading to damage to the body's immune system, causing immune function to decline or even loss, and resulting in the infection of various diseases or tumors.


TP first invades the skin at the site of infection, causing skin and peripheral lymph node lesions (primary syphilis). If left untreated, the spirochetes will spread throughout the body after entering the bloodstream, causing symptoms such as skin rash, fever, and swollen lymph nodes (secondary syphilis). If still left untreated or unresolved, the disease will further progress and lead to neurological disorders, cardiovascular disease, bone destruction, loss of vision, and other symptoms (tertiary syphilis).


3. Symptoms of onset

Acute HIV infection:

2-6 weeks after infection with HIV, symptoms similar to flu, such as fever, diarrhea, rash, and swollen lymph nodes appear. If left untreated, these symptoms generally resolve on their own. However, once AIDS is developed after a latent period of 2-8 years, systemic symptoms will occur, and failure to treat it in time may endanger one's life.


Typically, in the first 1-2 weeks, tiny round or oval hard nodules or pimple-like lesions appear on the genitals, which are firm around the periphery and quickly become ulcerated with no pus or discomfort. After 3-4 weeks, a red rash appears all over the body, taking on various shapes and lasting for a long time.

4. Treatment Method

HIV is treated with antiviral therapy, while TP is treated with antibacterial therapy.

5. Treatment Situation

Currently, there is no cure for AIDS, while syphilis can be cured if detected in its early stages, and the treatment methods are relatively simple (usually with long-acting penicillin injections), and the cost is relatively low.

6. Incubation Period

The incubation period of AIDS can be as long as 8-10 years, while the incubation period of syphilis is only 9-90 days, with an average of 3 weeks.

However, there are some similarities between AIDS and Syphilis:

1. Similar transmission routes

HIV can be transmitted through sexual contact, blood transmission (such as sharing needles when injecting drugs), and mother-to-child transmission (from infected mothers to infants), but it is not transmitted through daily contact.

TP can also be transmitted through the above three routes, but it should be noted that there is also a possibility of infection through daily contact with infected individuals, such as shaking hands, breastfeeding, and kissing.

2. Similar preventive measures

Donor screening ensures blood safety, sexual partners are mutually faithful, use of condoms, and mother-to-child blockade to prevent the transmission of the infection from an HIV-positive mother to her child.



AIDS and Syphilis are two common sexually transmitted diseases that pose a serious threat to human health. Currently, researchers have developed HIV recombinant antigens and TP recombinant antigens through genetic recombination technology, which have high diagnostic accuracy and therapeutic efficacy.

Both anti-HIV antibody and TP recombinant antigens have broad application prospects and market potential. If you would like to learn more about these products and how to purchase them, please feel free to consult our company.
