US from 1 July to 29 July.

The study found that adults with positive SARS-CoV-2 were twice as likely to report eating at a restaurant than negative SARS-CoV-2 results. Results highlight differences in community and close contact risk between adults who test positive for COVID-19 and those who test negative, and implications for risk factors that can be considered as countries around the world Is resuming activities.

The investigation noted that “exposures and activities where mask use and social disturbances are difficult to maintain may have significant risk factors for SARS-COV-2 infection.”

What does analysis tell us?

In the investigation, participants with and without COVID-19 reported largely similar community exposure, with the exception of those who engaged in eating on site. Essentially, the investigation suggests that adults with COVID-19 were twice as likely as control-participants (symptomatic adults with negative SARS-CoV-2 results) to have a restaurant 14 days before becoming ill. Was reported to eat in

In addition, approximately half of the participants reported people shopping or going inside their homes (in groups of 10 or less) for at least one day during the 14 days before the onset of symptoms.

Among adults with COVID-19, more than 49 percent reported having close contact with a COVID-19 positive person. Most of the close contact risks were with family members. On the other hand, among those who tested negative for COVID-19, approximately 14 percent reported close contact with a person who is COVID-19 positive.

So does eating out increase the chances of spreading the infection?

The investigation notes that reports of exposure in restaurants are linked to air circulation, as the direction, ventilation and intensity of airflow may affect virus transmission despite adhering to measures of social dissemination and use of masks. In addition, it is not always possible to wear masks in restaurants, which can increase exposure compared to activities such as shopping or going to one’s home, while indoor people do not need to take off their masks.

One of the earliest studies to prove it was a Chinese research that surfaced in April and talked about it The incident occurred in a restaurant in Guangzhou, ChinaIn which a coronavirus positive dinner was given to food, but not others, to nine more people passing through due to infection. In this study, researchers concluded that droplet transmission by air-conditioned ventilation.

What are the limitations of testing?

The study did not distinguish outdoor and indoor food and included only 314 pathogenesis individuals who sought testing at 11 centers in the US. Therefore, the results may not be representative of the general population. Participants were also aware of their test results, which may have influenced their reactions to community exposure and close contacts.
