The first Delta infection in the city may have occurred as early as June.
Executive Asst. V Felipe Puzon, Jr. of the city’s lead contact tracing team said back tracing and repeat interviews done on the first confirmed Delta variant patient and contacts revealed details pointing to the probability the Delta variant infection may have started in the city around June.
Mayor Benjamin Magalong on Aug. 16 said initial back tracing showed the variant may have been in the city since July.
But further investigation by the lead contact tracing team showed that one co-worker of the patient started experiencing symptoms on June 19. 
Puzon said the person had also been traveling prior to the onset of the symptoms.
He said the team is now establishing if the person is the index Delta case even as back tracing and link analysis continue to track down all contacts for administering of control measures like repeat tests and monitoring.
The first local Delta case, a 23-year-old male English as Secondary Language teacher, is part of the cluster of over 20 individuals who tested positive for the Covid-19 last July and have since recovered.
Although he was the first to be detected with the variant, it does not mean that he was the source of the infection, especially since he was not the index case in the cluster, according to the mayor.
All of them are now being looked into as probable Delta variant cases but the mayor said the number could go as high as 86.
Link analysis yielded 130 persons linked to the Delta case.
The more than 20 positive cases had already recovered and had mild symptoms except one who suffered from severe symptoms before recuperating. – Aileen P. Refuerzo
