SARS-CoV-2 RNA Detection on Disposable Wooden Chopsticks, Hong Kong

Category:

Topic:

  • SARS-CoV-2 RNA was detected on disposable wooden chopsticks used by 5 consecutive asymptomatic and post-symptomatic patients. This demonstrates a potential that chopsticks or other dining utensils could be a vehicle for transmission. This has potential implications for communal meals, especially in communities with a custom of sharing dishes or utensils.
