Health officials have revealed that the Auckland managed isolation facility worker who tested positive for Covid-19 used public transport several times prior to contracting the virus, Newshub reports. Case B, a security guard at Grand Millenium, rode Auckland Transport (AT) buses three times while potentially infectious on March 29, April 3 and April 4. Since Case B sat away from other passengers and wore a mask, his fellow passengers were classified as casual contacts per the Auckland Regional Public Health Service (ARPHS). Fellow passengers have been advised to watch out for Covid-19 symptoms and to undergo a test if they feel unwell.
