MEMPHIS - Tennessee health officials have raised the number of cases of new coronavirus in the state to nine.

Dozens of people remained quarantined or were under self-monitoring Wednesday as the Tennessee Department of Health added two cases to its list of patients with the virus that has sickened more than 1,000 people and killed 33 in the U.S.

Five cases have been confirmed in Williamson County, two in Davidson County, and one each in Shelby and Sullivan counties, the department said on its website.

For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.

The vast majority of people recover from the new virus. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three to six weeks to recover.
