Sydney engineer builds online map that marks out where Covid-positive cases have been

An engineer has created an interactive online map that shows every coronavirus exposure alert in Sydney.

Geospatial engineer Ken Tsang launched the Covid-19 Near Me website on Monday to help concerned Sydneysiders keep track of the latest infection locations.

The map marks every venue that has an active public health warning with a colour code to help distinguish between alert levels.

Mr Tsang’s map means residents will not have to find the official announcements by state authorities to know if they need to isolate or get tested.

Anyone who visited a venue marked with a red dot must isolate for 14 days.

People who have been to a location marked with an orange dot must isolate until they receive a negative test. 

Blue dots indicate that visitors should monitor their symptoms to ensure they are not infected, and green locations mean the venue no longer has a public health alert.

Mr Tsang announced the website on Twitter and said the information was constantly updated using figures from Data NSW and NSW Health.

‘Introducing Covid-19 Near Me (NSW) – a new tool to help you keep track of new case locations,’ he wrote.

Users can dismiss warning and notices they have already read, and the site will say what information has changed since the last time they visited the map.

Sydney residents were impressed with the website and said the resource was the clearest source of information they had seen.

‘Thank you. The clearest information I’ve seen to date,’ one user wrote.

‘It’s much better than the Govt site,’ another shared.

‘Thank you, this is great. Are we able to search by suburb, or am I not seeing that?,’ someone else asked.

‘Not yet! (but it is on my growing list of to-dos),’ Mr Tsang replied.

Another three cases all linked to the Northern Beaches outbreak were announced on Tuesday, taking the cluster to 129 patients.

NSW Health also announced a further three cases – to be included in Wednesday’s figures – with no known source.

Premier Gladys Berejiklian urged Greater Sydney residents to get tested after 16,000 people got swabbed on Tuesday, down from 70,000 on Thursday.

She said ‘Greater Sydney must be on high alert’ until the source of the three new mystery cases is found.

‘I say that in order to encourage as many people as possible across the state, even if you live in the regions, if you have the mildest of symptoms please come forward to get tested,’ Ms Berejiklian said.

The three new mystery cases mean there have now been 13 recorded in the past four weeks, including seven in northern Sydney.

They include a 20-year-old Belrose Hotel worker, a Belrose Hotel bottle shop customer, a Crows Nest firefighter who visited the hotel, and a man who worked in the CBD near Chifley Square.

There was also Paragon Hotel sports bar customer, a Bondi resident, a Western Sydney driver who transported flight crew to and from the airport and their hotels, and a hotel quarantine cleaner.

Chief Health Officer Dr Kerry Chant said there were 122 active cases in NSW with none in intensive care and 97 per cent being treated outside hospital.
