Nghe An quarantines and takes samples for testing of female student returning from Da Nang with fever and dry cough

(Baonghean.vn) - Health authorities are urgently spraying disinfectants, taking samples for testing, and conducting an epidemiological investigation of a case returning from Da Nang with symptoms of Covid-19.

Antibody tests, also known as serology tests, usually take only about an hour. Serology tests may not detect a recent infection, as it can take 1 to 3 weeks after symptoms appear for antibodies to be detected.

Therefore, Nghe An CDC is still conducting the second test. The results are expected to be available on the morning of July 31.

Two days later, she began to have symptoms of fever and dry cough. This morning, she had a high fever. Upon receiving the information, the health authorities immediately took the patient to the Vinh City Medical Center for isolation and treatment. Currently, Nghe An CDC is taking samples for testing of this patient.

Nghe An currently has more than 7,000 people returning from Da Nang and Quang Ngai in the past half month. These people are advised to quarantine at home for 14 days and proactively declare their health status.
