摘要: Transmission pathways of SARS-CoV-2 are aerosol, droplet and touching infected material. The diffusion the virus contagion among people is easier in indoor location, but direct detection air or on surfaces quite sparse, especially regarding public transport, while it would be important to know how if safe use them. To answer these questions we analysed most usually touched by passengers inside a city bus during normal operation, order understand possible spreading effectiveness protective measures. measurements were carried out across last week lockdown first when, gradually, all travel restrictions removed. surface samples with RT-PCR for virus. After two weeks more than 1100 passenger travelling was never detected both air, suggesting that precautions adopted transportation effective reducing COVID-19 spreading.
