Papillomaviruses May Be Able to Be Spread by Blood

Human papillomaviruses (HPVs) are a group of viruses that can cause warts and certain types of cancer. They are usually spread through skin-to-skin contact during sexual activity. However, recent research suggests that some types of papillomaviruses may also be able to be spread by blood.

What Are Papillomaviruses?

Papillomaviruses are a group of more than 200 related viruses. They are named after the warts (papillomas) that some of them cause. Most papillomaviruses are harmless and cause no symptoms. However, some types can cause warts on the skin or genital area, while others can cause cancer of the cervix, anus, penis, or throat.

How Are Papillomaviruses Spread?

Papillomaviruses are usually spread through skin-to-skin contact during sexual activity. They can also be spread from a mother to her baby during childbirth. In rare cases, they can be spread through non-sexual contact with an infected person's skin or objects that have come into contact with their skin.

Can Papillomaviruses Be Spread by Blood?

Recent research suggests that some types of papillomaviruses may be able to be spread by blood. A study published in the journal Emerging Infectious Diseases found that nearly 4% of blood donors in Brazil tested positive for HPV DNA. The researchers believe that the virus may be able to infect blood cells and survive in the bloodstream.

What Are the Implications of This Discovery?

The discovery that some types of papillomaviruses may be able to be spread by blood has important implications for blood transfusions and organ transplants. Currently, blood donors are screened for a number of infectious diseases, including HIV, hepatitis B and C, and syphilis. However, they are not routinely screened for HPV.

If HPV can be spread by blood, it may be necessary to develop new screening tests for blood donors and organ donors. It may also be necessary to consider the risk of HPV transmission in certain medical procedures, such as surgery.

How Can You Protect Yourself from Papillomavirus Infection?

The best way to protect yourself from papillomavirus infection is to practice safe sex. This means using condoms during sexual activity and limiting your number of sexual partners. It is also important to get vaccinated against HPV. The HPV vaccine is recommended for both boys and girls starting at age 11 or 12.

Conclusion

Papillomaviruses are a group of viruses that can cause warts and certain types of cancer. They are usually spread through skin-to-skin contact during sexual activity. However, recent research suggests that some types of papillomaviruses may also be able to be spread by blood. This discovery has important implications for blood transfusions and organ transplants. To protect yourself from papillomavirus infection, practice safe sex and get vaccinated against HPV.
