Aplastic anemia


If my boyfriend has acquired aplastic anemia caused by a virus and has recovered through self-treatment, will it be hereditary to our children, or can it be transmitted to me through oral sex or similar means?

More Info


Aplastic anemia is a rare but serious condition characterized by the failure of the bone marrow to produce adequate blood cells, leading to a deficiency in red blood cells, white blood cells, and platelets. This condition can be caused by various factors, including autoimmune diseases, exposure to certain chemicals, radiation, and viral infections. In your case, it appears that your boyfriend's aplastic anemia was acquired due to a viral infection, which is an important detail when considering the risks of transmission and inheritance.

To address your concerns:
1. Inheritance Risks: Aplastic anemia, especially when acquired (as opposed to inherited forms), is not typically passed down to children. Since your boyfriend's condition is due to a viral infection and not a genetic disorder, it is unlikely that he would pass this condition on to any future children. Genetic forms of aplastic anemia, such as Fanconi anemia, can be inherited, but these are distinct from acquired aplastic anemia. Therefore, if your boyfriend's aplastic anemia was indeed caused by a virus and he has since recovered, the risk of passing on the condition genetically is negligible.

2. Transmission Risks: Aplastic anemia itself is not contagious. It is a result of the bone marrow's inability to produce blood cells, which can be triggered by various factors, including infections. However, the underlying viral infection that caused his aplastic anemia may have been contagious at the time of infection. If the virus was a transmissible one (like certain types of hepatitis or parvovirus), there could have been a risk of transmission during the active phase of the infection. However, once he has recovered and the virus is no longer present in his system, the risk of transmission through activities such as oral sex is minimal. It is important to note that the specific virus involved would determine the actual risk of transmission, and some viruses can remain dormant in the body without causing symptoms.

3. Precautions: If you are concerned about potential exposure to any viruses, it would be wise to discuss this with your boyfriend and possibly consult with a healthcare provider. They can provide more specific information based on the type of viral infection he had and any necessary precautions you might need to take.

4. Monitoring Health: If your boyfriend has fully recovered from his aplastic anemia, it is essential for him to continue regular follow-ups with his healthcare provider. Monitoring his blood counts and overall health is crucial, as there can be long-term effects from the condition and its treatment.

In summary, while aplastic anemia itself is not hereditary or contagious, the underlying causes can vary. If your boyfriend's condition was due to a viral infection and he has since recovered, the likelihood of passing it on to children or transmitting it to you is very low. However, maintaining open communication with your boyfriend about his health and any concerns you have is essential for both of you.

If one spouse is a carrier of thalassemia (Mediterranean anemia) and the other spouse is not, is there a possibility of inheritance, and what is the probability?


Dr. Wang Hanzhou reply Obstetrics and Gynecology
The probability of passing on the trait to the offspring is 1/2 for a recessive carrier and 1/2 for a completely normal individual (AA Bb → AB AB Ab Ab). There is no possibility of severe thalassemia, so there is no need to worry.
