Another case report published by the CDC — this time from Singapore — also suggests contact with contaminated surfaces can transmit the virus. In that case, a person who was infected with SARS-CoV-2, but not yet symptomatic, attended a church service. Later in the day, another person sat in the same seat, and also came down with COVID-19. Whether the virus was contracted via a contaminated surface, or potentially a lingering aerosol, however, couldn't be ascertained.
