Bloodborne Diseases and Blood Transfusions

Blood transfusions are a crucial medical procedure used to replace lost components of the blood. While they save countless lives each year, there is a small risk of transmitting infectious diseases through transfusion. Over the years, rigorous screening and testing have greatly reduced these risks. Nevertheless, understanding potential bloodborne diseases remains important for both patients and healthcare providers.

Hepatitis B and C Viruses

Hepatitis B and C are viral infections that primarily affect the liver. Hepatitis B can cause both acute and chronic liver disease, while Hepatitis C is more likely to lead to chronic infection. Both viruses can be transmitted through blood transfusions if the blood is infected. In the UK, stringent screening reduces the likelihood of these viruses being present in donated blood. Nevertheless, vigilance is key, since chronic hepatitis infections can result in severe liver damage over time.

Human Immunodeficiency Virus (HIV)

Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, leading to Acquired Immunodeficiency Syndrome (AIDS) if not treated. Despite advancements in antiretroviral therapy, preventing transmission remains a priority. Donated blood in the UK is subject to rigorous HIV testing to minimise the risk of transference through transfusions.

Human T-lymphotropic Virus (HTLV)

Human T-lymphotropic Virus (HTLV) is another virus that can be transmitted through blood transfusion. Primarily, it is linked to certain forms of leukemia and neurological disorders. Like other bloodborne viruses, it is relatively rare in the UK as blood is routinely screened for HTLV to prevent its transmission.

Syphilis

Syphilis is a bacterial infection typically spread through sexual contact but can be transmitted via blood. The bacteria, Treponema pallidum, can cause long-term complications if not treated. Comprehensive screening of blood donors for syphilis greatly reduces the risk of transmission through blood transfusions.

Malaria

Malaria is a tropical disease caused by Plasmodium parasites, transmitted through bites from infected mosquitoes. While it is not endemic in the UK, individuals who have travelled to malaria-prone regions may transmit it via blood transfusions. Screening for malaria exposure is part of donor screening procedures to help prevent transmission.

Zika Virus

Zika virus is primarily spread through mosquito bites, but it can also be transmitted via blood transfusions. The virus has gained attention due to its potential to cause birth defects if contracted during pregnancy. Donor screening practices include assessing travel history to regions where Zika is prevalent.

Preventive Measures in the UK

The UK has implemented stringent blood screening measures to protect recipients from bloodborne infections. Blood donations are thoroughly tested for viruses and other pathogens, and potential donors are screened for risk factors before donation. This multi-layered approach significantly reduces the risk of disease transmission through blood transfusions, ensuring safety and public confidence in blood donation services.

Bloodborne Diseases and Blood Transfusions

Blood transfusions are when doctors give people new blood to help them get better. They save many lives. But sometimes, they can pass on diseases. Many checks are done to make sure this doesn’t happen. Knowing about these diseases helps doctors and patients stay safe.

Hepatitis B and C Viruses

Hepatitis B and C are viruses that can hurt the liver. Hepatitis B can make people very sick for a short or long time. Hepatitis C usually makes people sick for a long time. These viruses can spread through blood transfusions if the blood is not checked properly. In the UK, blood is carefully checked to keep it safe. But being careful is important because these viruses can damage the liver badly.

Human Immunodeficiency Virus (HIV)

Human Immunodeficiency Virus (HIV) hurts the body's defense system. This can lead to a disease called AIDS if not treated. Doctors work hard to stop HIV from spreading. In the UK, all donated blood is tested for HIV to keep it safe for everyone.

Human T-lymphotropic Virus (HTLV)

Human T-lymphotropic Virus (HTLV) can also spread through blood transfusions. It is connected to some blood and nerve diseases. It is rare in the UK because blood is tested for HTLV before it is used.

Syphilis

Syphilis is an infection that usually spreads through close contact but can also spread through blood. If not treated, it can cause serious problems. Blood donors are tested for syphilis to make sure the blood is safe.

Malaria

Malaria is an illness from mosquito bites in hot countries. People who have traveled to places with malaria might carry it in their blood. The UK screens blood donors who have traveled to these areas to make sure no malaria is passed on through transfusions.

Zika Virus

Zika virus mostly spreads through mosquito bites and can also spread through blood transfusions. It can harm babies if a mother gets it when pregnant. Blood donors are checked for travel to areas with Zika to keep the blood supply safe.

Preventive Measures in the UK

In the UK, there are strong rules to keep blood safe. Blood donations are tested for diseases, and people are asked questions to check if they are good donors. This makes blood transfusions in the UK very safe, giving people confidence to receive and donate blood.
