Transmission routes of COVID-19?

Hello, Doctor.
Today, I had the rare opportunity to go out with my mom for lunch and to pray.
During lunch, there was a guy at the next table who was coughing towards us.
I thought we were about to eat and took off my mask, but my mom told me it was fine to take it off while eating.
After we finished praying, I was feeling thirsty, so I pulled down my mask to drink water.
My mom then said that I should have used hand sanitizer with alcohol before touching my mask, as it could be dangerous.
Although I understand that my mom is worried about me, I didn't eat anything; I just pulled down my mask to drink water.
Is there still a possibility of infection from this? After hearing her, I became a bit concerned! Thank you for your response!

Hello: The concerns you have are shared by many people in today's society.
Your mother's requests are cautious and correct, especially when it comes to public places.
Your first concern is about the boy at the next table coughing and possibly infecting you.
This issue involves three aspects: first, if he is wearing a mask, the risk of infection is lower; second, if you are more than 1.5 meters away, the likelihood of infection is reduced; third, since there are currently no local COVID-19 cases, the chances of infection are minimal.
However, your mother's reminders and requests are valid.

Your second concern is about not washing your hands after throwing away a cup.
In fact, your mother's request is correct.
It is essential to wash your hands or use hand sanitizer with alcohol before consuming food; this is a good habit that everyone should develop, regardless of whether it is during a COVID-19 outbreak.

Wishing you safety and health.
Family Physician, Wu Zong-Ying.

When it comes to understanding the risks of COVID-19 transmission in everyday situations, it's essential to consider various factors, including the environment, personal behaviors, and the presence of others. Your concerns about removing your mask while eating and drinking, especially in the presence of someone who was coughing, are valid and reflect a common apprehension during the ongoing pandemic.

Firstly, COVID-19 primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. If someone nearby is coughing, there is a potential risk of exposure, particularly if they are not wearing a mask. In such situations, it is advisable to maintain physical distance whenever possible. While eating, it is common to remove your mask, but you should be cautious about the proximity of others who may be unwell.

Regarding your specific actions—removing your mask to drink water after using a shared cup—there are a few points to consider. If the cup was used by someone else, there is a risk of surface transmission, although this is generally considered to be a less significant route of transmission compared to respiratory droplets. If you did not sanitize your hands before touching your face or removing your mask, this could increase your risk of infection. Hand hygiene is crucial; using alcohol-based hand sanitizer before and after touching your face or mask can help mitigate this risk.

Your mother's concerns about using hand sanitizer are well-founded. Regular hand washing or using hand sanitizer, especially after touching shared surfaces or objects, is a key preventive measure against COVID-19. It is also important to avoid touching your face, particularly your mouth, nose, and eyes, with unwashed hands.

In terms of risk assessment, while your actions do carry some risk, the overall likelihood of transmission depends on several factors, including the vaccination status of those around you, the ventilation of the space, and the prevalence of COVID-19 in your community. If you are in a well-ventilated area and the person who was coughing is not confirmed to have COVID-19, the risk may be lower. However, it is always better to err on the side of caution.

To further reduce your risk in similar situations, consider the following recommendations:
1. Wear a Mask: Continue wearing a mask in crowded or enclosed spaces, especially when you cannot maintain physical distance from others.

2. Maintain Distance: Try to keep a safe distance from others, particularly if someone appears to be unwell.

3. Practice Good Hand Hygiene: Use hand sanitizer frequently, especially after touching shared items or surfaces.

4. Limit Shared Items: If possible, avoid sharing cups or utensils, as this can reduce the risk of surface transmission.

5. Stay Informed: Keep up to date with local health guidelines and recommendations regarding COVID-19, as these can change based on the current situation in your area.

In conclusion, while your actions do carry some risk, being mindful of your surroundings and practicing good hygiene can significantly reduce the likelihood of transmission. If you have any symptoms or concerns about potential exposure, consider getting tested and consulting with a healthcare professional for further guidance.
