Hello, regarding your question, here is an excerpt from the Centers for Disease Control website for your reference.
In the event of an animal bite, please follow these steps: 1.
Record: Stay calm and remember the characteristics of the animal.
2.
Wash: Rinse the wound with plenty of soap and water for 15 minutes, and then disinfect the wound with povidone-iodine.
3.
Seek medical attention: Go to a healthcare facility as soon as possible to assess whether vaccination is needed.
4.
Observe: If possible, restrain the biting animal for observation for 10 days.
If the animal shows aggressive behavior, do not attempt to capture it.

Where to seek medical attention after an animal bite: 1.
Please visit a designated vaccination hospital; there are vaccination points available in every county and city.
Since January 1, 2014, rabies vaccines and immunoglobulin for humans have been included in the National Health Insurance coverage.
2.
High-risk individuals exposed to rabies must receive 5 doses of the vaccine, and vaccination should occur before the onset of symptoms, with an effectiveness close to 100%.

Treatment methods and medical information: 1.
If bitten or scratched by a mammal, immediately wash the wound with soap and water for 15 minutes, disinfect with povidone-iodine or 70% alcohol, and seek medical attention for further cleaning and treatment.
Based on the physician's diagnosis and assessment, preventive measures for tetanus and other necessary infection controls, rabies immunoglobulin, and post-exposure vaccination will be administered.
2.
When seeking medical attention, proactively inform the physician about your animal exposure history and travel history to receive appropriate treatment as early as possible.
3.
Rabies is a serious concern in mainland China; if bitten by an animal there, it is recommended to seek treatment at a provincial or city-level disease control center or a public hospital at the provincial or city level for better quality of care.

Thank you for your inquiry.

More Info

When it comes to the rabies virus, understanding its transmission and survival outside the host is crucial for effective prevention and control. The rabies virus is primarily transmitted through the saliva of infected animals, typically via bites. Once the virus enters the body, it travels along the nervous system, leading to severe neurological symptoms and, ultimately, death if not treated promptly.

Regarding your question about laundry detergent and its effectiveness against the rabies virus, it's important to note that the rabies virus is relatively fragile when exposed to environmental conditions. It does not survive long outside a host, especially in dry conditions. However, it can remain viable in fresh saliva or other bodily fluids for a limited time.

Most household detergents, including laundry detergents, are designed to break down organic materials and can effectively clean surfaces and fabrics. While there is no specific study that directly tests the efficacy of laundry detergent against the rabies virus, it is generally accepted that detergents can help in deactivating many viruses and bacteria due to their surfactant properties. Surfactants work by disrupting the lipid membranes of viruses, which can lead to their inactivation.

To ensure safety when dealing with potential rabies exposure, it is essential to follow specific cleaning protocols. If there is a concern about contamination from an animal bite or exposure to saliva from a rabid animal, it is advisable to:
1. Clean the Area Thoroughly: Use soap and water to wash the wound immediately after exposure. This is the most critical step in preventing rabies transmission.

2. Use Disinfectants: After washing, applying a disinfectant that is known to be effective against viruses can provide an additional layer of safety. Common disinfectants include bleach solutions (diluted appropriately) or alcohol-based solutions.

3. Launder Contaminated Fabrics: If clothing or fabrics have been contaminated with saliva or blood from a potentially rabid animal, washing them in hot water with a good quality laundry detergent is advisable. Adding bleach (if the fabric allows) can further enhance the disinfecting process.

4. Seek Medical Attention: If there is any suspicion of rabies exposure, it is crucial to seek medical attention immediately. Post-exposure prophylaxis (PEP) with rabies vaccine and immunoglobulin can be life-saving if administered promptly.

In summary, while laundry detergent can aid in cleaning and may help in deactivating the rabies virus on fabrics, it is not a substitute for proper wound care and medical intervention. Always prioritize immediate cleaning of wounds and seek professional medical advice in cases of potential rabies exposure.
