Introduction
Generally, viruses such as smallpox virus, rabies virus, and hepatitis B virus have relatively high transmission probabilities. After the onset of hepatitis B, it is mainly important to assess whether the virus has caused damage to antibodies, and treatment methods should be rationally selected based on the specific condition. In addition, HIV-related diseases are also widely transmitted; thus, early detection and early intervention are strongly recommended.
Generally, viruses such as smallpox virus, rabies virus, and hepatitis B virus have relatively high transmission probabilities.
1. Smallpox virus
The smallpox virus usually spreads through the respiratory mucosa, via droplets, or through direct contact. After transmission, symptoms such as fever, headache, and muscle aches may occur. After onset of illness, supportive treatments under medical guidance—such as intravenous fluids or symptomatic medications—can be used.
2. Rabies virus
Rabies virus is primarily transmitted when an animal's saliva containing the virus comes into contact with a human, potentially causing infection that leads to fever and other symptoms. As there are no specific antiviral drugs available after being bitten, prompt administration of the rabies vaccine is essential.
3. Hepatitis B virus
After onset of hepatitis B, transmission commonly occurs through blood or from mother to child. Accidental exposure in daily life may easily trigger infection. Following diagnosis, treatment depends on whether the virus has caused damage to antibodies, and appropriate therapeutic approaches should be selected based on the individual clinical condition.
In addition, HIV-related diseases are also widely transmitted; early detection and early intervention are strongly recommended.
