SARS-CoV-2, the virus that causes COVID-19, has been the most common cause of influenza-like illnesses (ILI) in the country since the pandemic in 2020, according to data from the Department of Health (DOH).

Among those tested with RT-PCR test, an overwhelming majority of ILI cases nationwide were traced to the virus SARS-CoV-2 in 2020 (with 1,194 cases), 2021 (with 8,247 cases) and 2022 (3,541 cases).

ILI infections in 2020 and 2021 with SARS-CoV-2 as the causative agent were found in about 98 percent of the total cases in both years. In 2022, ILI cases found to have been caused by SARS-CoV-2 accounted for around 89 percent of the total.

From Jan. 1 to Sept. 16 this year, SARS-CoV-2 remained the leading causative agent of ILI at a total of 536 cases, comprising 44.69 percent of the total samples tested.

It was followed by influenza A (15.54 percent), rhinovirus (11.05 percent), parainfluenza (8.8 percent).

The rest were influenza B (3.18 percent), adenovirus (2.68 percent), enterovirus (1.87 percent) and respiratory syncytial virus (1.69 percent).
