Taipei, April 4 (CNA) Two hundred and four residents of a luxury residential complex have been placed under close watch after a female security guard working there tested positive for COVID-19, the Central Epidemic Command Center (CECC) said Saturday.

After the security guard at the complex in northern Taiwan was confirmed to have COVID-19 Thursday, a total of 388 people, including the 204 residents, were either placed in home quarantine or asked to undergo self-health management by the CECC.

Chuang Jen-hsiang, deputy director general of the Centers for Disease Control and CECC spokesman, told reporters that a test has been conducted on one resident who developed a fever.

The results are expected in one day, according to the CECC.

In addition to the 204 residents in the residential compound, the 388 placed under close supervision also include five family members of the security guard and a female friend who was confirmed as having contracted the virus Friday.

The confirmed case on Friday came after the patient, in her 40s, who lives in a nearby neighborhood was seen, through surveillance footage, talking with the female security guard for more than 20 minutes with neither wearing a face mask.

The CECC said the security guard, in her 50s, most likely contracted the virus at work rather than home because she lives in a remote mountainous area and rides a motorcycle to work.

The CECC added that the female guard and her friend came into direct contact with 142 people, with six of them being tested.

The female security guard is one of the domestic infection cases the infection source of which is unknown. A man, in his 40s, was also confirmed to have contracted COVID-19 Saturday without any indication of an infection source, the CECC said.

The CECC cited the man, who worked at a shop in northern Taiwan, as saying he wore a face mask while working and did not go to work the day he developed a fever.

The CECC said a total of nine individuals have been put under watch related to the man, seven in the workplace and two friends.

According to the CECC, the man is the first COVID-19 patient in Taiwan who lost his senses of smell and taste.

On Saturday, seven new COVID-19 confirmed cases were reported in Taiwan, increasing the total in the country to 355 with five deaths since the pandemic began in China at the end of December.

Worldwide, COVID-19 has infected 1,074,272 patients in 181 countries and regions, including 270,473 in the U.S., 119,827 in Italy, 117,710 in Spain, 81,639 in China and 79,696 in Germany, with a total of 58,053 fatalities to date, the CECC said.
