SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)
Hello, doctor! I have an online shopping package that was shipped by the seller on June 18th, and I opened it on June 22nd.
I have already sprayed the outside of the box with alcohol.
My question is, will there still be any virus residue on the items inside the package? Thank you! (The package was sent from Longtan, Taoyuan!)

Hello! According to relevant studies, the COVID-19 virus can survive on cardboard for approximately 24 hours, but this finding comes from laboratory research and may not fully reflect real-world conditions.
Factors such as temperature and humidity also need to be considered.
This is for your reference.

When it comes to the risk of COVID-19 transmission from packages, it's important to understand how the virus behaves on surfaces. Research has shown that the SARS-CoV-2 virus, which causes COVID-19, can survive on various surfaces for different lengths of time, depending on factors such as the material, temperature, and humidity. However, the risk of contracting COVID-19 from surfaces, including packages, is considered to be low.
In your case, since you have already disinfected the outer packaging of your online order with alcohol, you have significantly reduced any potential risk of virus transmission. Alcohol-based disinfectants are effective at killing the virus on surfaces, provided they are used correctly and allowed to remain on the surface for an adequate amount of time.
Here are some key points to consider regarding your package and the risk of COVID-19:
1. Surface Stability: Studies indicate that the virus can remain viable on cardboard for up to 24 hours, but this does not mean it is infectious after that time. The viral load decreases significantly over time, and by the time you opened your package, it is likely that any virus present would have been reduced to negligible levels.
2. Disinfection: By using alcohol to disinfect the outer packaging, you have taken an important step in minimizing any potential risk. It is recommended to use a disinfectant with at least 70% alcohol concentration and to ensure that the surface remains wet for a sufficient period to effectively kill the virus.
3. Handling Precautions: After disinfecting the outer packaging, it is advisable to wash your hands thoroughly with soap and water or use hand sanitizer before touching your face or consuming any items from the package. This is a good practice to further reduce any risk of transmission.
4. Risk of Transmission: The primary mode of transmission for COVID-19 is through respiratory droplets when an infected person coughs, sneezes, or talks. The likelihood of contracting the virus from a surface is much lower compared to direct person-to-person contact. Therefore, the risk of getting infected from a package is minimal, especially after disinfection.
5. Ongoing Precautions: While the risk from packages is low, it is still wise to continue practicing good hygiene. This includes regular hand washing, wearing masks in crowded places, and maintaining social distancing when necessary.
In summary, after disinfecting the outer packaging of your online order, the risk of any remaining COVID-19 virus on the items inside is very low. You have taken appropriate measures to ensure safety. Continue to practice good hygiene, and you can feel more at ease about handling your package. If you have any further concerns or experience any symptoms, it is always best to consult with a healthcare professional.
