Can hepatitis B be transmitted between spouses?

Introduction

Under normal circumstances, "Yigan" refers to hepatitis B. Whether hepatitis B can be transmitted between spouses depends on the specific circumstances. If the hepatitis B virus in the infected individual is not actively replicating, transmission may not occur; however, if the virus is actively replicating, transmission between spouses may happen.

Generally speaking, hepatitis B refers to Hepatitis B Virus (HBV) infection. Whether HBV can be transmitted between married couples depends on specific circumstances. If the HBV-infected individual has a low level of viral replication, transmission may not occur; however, if the virus is actively replicating in the infected individual, transmission between couples is possible. Detailed analysis is as follows:

HBV is mainly transmitted through blood, sexual contact, and mother-to-child transmission. If one partner has a low viral load and the virus is not actively replicating, the infectivity is relatively low. In addition, if the uninfected partner has already received the hepatitis B vaccine and developed sufficient antibodies, the chance of infection is relatively small.

Between married couples, due to the presence of intimate contact and sexual activity, sexual transmission becomes a primary route of HBV transmission. If the infected partner has a high viral load and active viral replication, the likelihood of transmitting the virus to the other partner is relatively high. Moreover, long-term close contact with an HBV carrier, such as sharing personal items that may be contaminated with blood (e.g., toothbrushes, razors), may also lead to infection.

It is recommended that couples take appropriate protective measures during sexual activity, such as using condoms, to reduce the risk of HBV transmission.

What is the probability of entecavir causing fetal malformations?

If entecavir must be used during pregnancy due to therapeutic needs (e.g., active chronic hepatitis B), the physician will decide on the treatment plan after comprehensively evaluating the patient's condition and potential risks. Clinical observations to date have not shown a significantly higher incidence of fetal malformations compared to the general population; however, regular prenatal examinations are necessary to closely monitor fetal development and promptly identify any potential abnormalities.

Which is more serious: hepatitis B or hypertension?

In general, the severity of hepatitis B and hypertension cannot be generalized, and must be assessed based on individual conditions, complications, treatment response, and other factors. If any discomfort occurs, it is recommended to seek medical attention promptly. Regular health check-ups are important in daily life for early detection and early intervention. Patients with hepatitis B should follow medical advice to monitor liver function and viral load, and avoid liver-damaging behaviors such as alcohol consumption and staying up late.

Can hepatitis B surface antigen disappear?

In general, the hepatitis B surface antigen may disappear, but it does not vanish in all cases. The likelihood and speed of its disappearance are closely related to the type of infection, the patient's immune status, and whether standardized treatment is received. For both acute and chronic infections, regular testing of hepatitis B viral markers is necessary to confirm whether the hepatitis B surface antigen has disappeared.

Can the interval between hepatitis B vaccine doses be shortened?

Under normal circumstances, the interval between hepatitis B vaccine doses should not be shortened arbitrarily and must strictly follow the national recommended standard schedule. In special cases, any adjustment should only be made after evaluation by a physician, as shortening the interval without guidance may compromise the immune response. The general population should receive hepatitis B vaccinations according to the standard recommended intervals. If vaccination is delayed due to special reasons, individuals should consult a doctor for appropriate adjustments and must not shorten the interval on their own.

How many years does the hepatitis B vaccine provide protection?

In general, the protective effect of the hepatitis B vaccine typically lasts for 5 to 10 years. In some individuals, antibody levels remain high after vaccination, allowing protection to extend beyond 10 years. The exact duration should be determined based on individual antibody levels. It is recommended to regularly test for antibodies and decide whether a booster dose is needed according to the results. In daily life, it is important to avoid contact with blood, bodily fluids, and other potential sources of infection from individuals with hepatitis B.

Can hepatitis B virus cause fetal malformations?

The hepatitis B virus itself usually does not directly cause fetal malformations; its primary risk is transmitting the virus to the fetus. To reduce the risk of mother-to-child transmission, pregnant women who are hepatitis B surface antigen positive should receive antiviral interventions under medical guidance, including appropriate use of antiviral medications during pregnancy and timely administration of hepatitis B immunoglobulin and the first dose of hepatitis B vaccine to the newborn after birth.

Are hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) positive results infectious?

HBsAg negative, anti-HBs positive, HBeAg negative, anti-HBe negative, and anti-HBc positive (i.e., positive for the second and fifth markers) usually indicates no infectivity. This result suggests a past hepatitis B virus infection that has resolved, with development of immunity against hepatitis B. Individuals with positivity only for the second and fifth markers do not need to worry about transmitting the virus and require no special treatment. It is recommended to periodically check the titer of hepatitis B surface antibody; if the titer drops below the protective level, appropriate measures such as booster vaccination may be considered.

Can chronic hepatitis B progress to liver cirrhosis or liver cancer?

In general, whether chronic hepatitis B will progress to cirrhosis or liver cancer depends on a comprehensive assessment of factors such as disease control, treatment adherence, and lifestyle. It is important to initiate standardized treatment promptly after diagnosis, without arbitrarily adjusting medication doses or discontinuing treatment. Regular follow-up examinations should be maintained to monitor liver function, viral load, and changes in liver imaging.
