China outbreak 'may have started earlier'
A surge in road traffic outside Wuhan hospitals at the end of August suggests that Covid-19 may have hit China earlier than reported by the authorities, according to a Harvard Medical School study.
Using commercial satellite imagery, researchers found a "dramatic increase" in traffic outside five major hospitals in the Chinese city. The traffic spike also coincided with a rise in online searches for information on symptoms like "cough" and “diarrhea”.
Dr John Brownstein, who led the research, said the evidence was circumstantial, but told ABC News that it would provide important context in the search for the virus' origins.
“Something was happening in October,” said Dr Brownstein. “Clearly, there was some level of social disruption taking place well before what was previously identified as the start of the novel coronavirus pandemic.”
On 31 December 2019, China reported a cluster of pneumonia cases with an unknown cause to the World Health Organization. Nine days later, Chinese authorities revealed they had detected a novel coronavirus (later named Sars-CoV-2, the virus causing Covid-19) in several of the pneumonia cases.

I have always felt this has been here for about 6 weeks earlier than China had reported.
Does anyone else feel the same?
