Assessing the Risk of COVID-19 Transmission in Public Dining Settings

Transmission potential of Wuhan pneumonia (COVID-19)

Hello, doctor.
Although I know that the pandemic situation in the country has eased, I tend to be quite anxious and often catch colds.
Today, I was reluctantly taken by my family to a buffet at Han Lai Harbor Restaurant.
There happened to be four Japanese people sitting at the table in front of us.
Now, whenever I see foreigners, I feel a bit scared for no reason.
The restaurant clearly stated that masks should be worn while serving food and that conversations should be avoided, but there was no English sign, let alone Japanese.
During the meal, I was very nervous, worried that they might be carriers of the virus, even though they didn’t seem to be coughing.
We had our temperatures checked when entering Dunhua SOGO, and I assume they did the same at the entrance of the restaurant.
After eating, I suddenly felt a slight itch and mild pain in my throat.
I’m not sure if it’s because my cold hasn’t fully resolved; it was more painful a few days ago, but it’s less painful now after taking medication.
The doctor said I only had a mild cold.
I would like to ask you, doctor, how high is the risk of me contracting COVID-19 from this situation? It feels quite frightening to see foreigners now.
My family says that my throat pain and itchiness are just due to my cold not being fully resolved and that I might be exaggerating my feelings due to anxiety.
They mentioned that it’s possible to develop symptoms two hours after eating.
I’m unsure of your opinion on whether I should go to the emergency room for testing or if I should just finish my remaining medication.
The ENT doctor said I wouldn’t need to come back if I took the medication again.
I’m really worried, so I came to ask.
Thank you.

Hello, although it's mealtime, based on your description, it seems that the other person was at a different table.
Currently, there are no local cases in Taiwan, and all foreign entrants are required to undergo a 14-day quarantine, so it is unlikely that you have COVID-19.
However, there are many other respiratory viruses circulating recently, such as rhinoviruses and adenoviruses, which could be responsible for your symptoms.
I recommend getting plenty of rest, staying hydrated, and exercising regularly.
Wishing you a speedy recovery.
Thank you for your question.

When it comes to assessing the risk of COVID-19 transmission in public dining settings, especially in the context of your recent experience at a buffet restaurant, there are several factors to consider. The current COVID-19 situation in your area, the precautions taken by the restaurant, and your personal health concerns all play a significant role in determining your risk.

Firstly, it's important to note that the risk of transmission in a dining setting can be influenced by several key factors:
1. Vaccination Status: If you are fully vaccinated and have received your booster shots, your risk of severe illness from COVID-19 is significantly reduced. Vaccination helps to lower the chances of contracting the virus and spreading it to others.

2. Masking and Social Distancing: You mentioned that the restaurant had rules in place for wearing masks while serving food. This is a crucial measure to reduce transmission. If diners are wearing masks when not eating and maintaining a distance from others, the risk of airborne transmission decreases. However, once masks are removed for eating, the risk can increase, especially if people are in close proximity.

3. Ventilation: The ventilation of the dining area is another critical factor. Well-ventilated spaces allow for better air circulation, which can help dilute any viral particles in the air. If the restaurant has good ventilation, this can further reduce your risk.

4. Duration of Exposure: The longer you are in close proximity to someone who may be infected, the higher your risk of transmission. In your case, if you were seated at a distance from the individuals at the next table and they were not coughing or showing symptoms, the risk of transmission would be lower.

5. Personal Health: You mentioned experiencing a sore throat and discomfort. While this could be a sign of a mild cold or other viral infection, it is also important to monitor your symptoms. If you are feeling unwell, it is advisable to take precautions, such as self-isolating and getting tested for COVID-19, especially if you have had potential exposure.

Regarding your concerns about the possibility of contracting COVID-19 from the individuals at the restaurant, it is essential to remember that the likelihood of transmission is generally lower when proper precautions are in place. Since you noted that the restaurant was following guidelines, and if you maintained a reasonable distance from others, your risk of contracting the virus is likely low.

However, if you continue to feel unwell or if your symptoms worsen, it would be prudent to seek medical advice. Testing for COVID-19 can provide peace of mind and help ensure that you are not unknowingly spreading the virus to others. Additionally, if you are feeling anxious about your health, discussing your concerns with a healthcare provider can help address your fears and provide guidance on the next steps.

In summary, while the risk of COVID-19 transmission in public dining settings exists, following safety protocols, being aware of your surroundings, and monitoring your health can significantly mitigate that risk. If you have any lingering concerns or symptoms, do not hesitate to consult with a healthcare professional for further evaluation and guidance.
