How long does hepatitis E need to be isolated?

summary

Hepatitis E is also a viral hepatitis, so it is also contagious. Its epidemic characteristics are similar to those of hepatitis A, which incidence rate is high in some developing countries and the intensity of transmission is very strong. Once China has detected hepatitis E, isolation treatment is necessary. So, how long does hepatitis E patients need to be isolated? Here is my introduction to this problem.

How long does hepatitis E need to be isolated?

First, the main route of transmission of hepatitis E is through the digestive tract, the disease is more serious than hepatitis A, and the mortality is higher than that of hepatitis A. In view of the problem of how long the Lich of hepatitis E is isolated, experts have done an examination. The examination results show that among the detected patients with hepatitis E, the main attack time of the patients' detoxification and viremia is in the four weeks, so the infectivity of patients with hepatitis E is mainly in the four weeks, so the isolation of patients with hepatitis E should be around four weeks.

Second: vertical transmission: after hepatitis E virus infects the mother, the mother can transmit it to the fetus, which is also the cause of intrauterine stillbirth and abortion in pregnant women with hepatitis E. The fetal death, non explosive abortion and intrauterine stillbirth caused by fulminant liver failure are all caused by intrauterine infection of hepatitis E virus.

Third: fecal oral transmission: it is generally caused by fecal pollution of water source, which is usually in the form of outbreak or epidemic. Therefore, the peak of incidence is mostly after rainy season or flood, and the epidemic scale should be determined according to the degree of water source pollution. There are many ways of transmission, such as contact in daily life, through contact with contaminated tools, hands or direct contact port. It can also be transmitted through water sources. Generally, water sources are polluted by feces. Food pollution can also lead to the spread of the virus. Eat food contaminated by feces with hepatitis E virus, especially shellfish or vegetables that are not cooked.

matters needing attention

After reading the above introduction, we also know that the transmission route of hepatitis E is very wide. We also know that the isolation time of hepatitis E is four weeks, and the harm of hepatitis E to human health is relatively large, which can lead to the death of patients. Therefore, we should remind everyone to pay attention to the treatment and prevention of hepatitis E, understand the transmission route of hepatitis E, and pay attention to domestic water and drinking water in daily life Food hygiene, prevention.
