LATEST CONFIRMED CASES OF COVID-19 IN SOUTH AFRICA (22 April 2022)

The National Institute for Communicable Diseases (NICD), a division of the National Health Laboratory Service, continues to monitor various data sources related to the evolving nature of South Africa’s COVID-19 pandemic.

Today, the institute reports 4,631 new COVID-19 cases in South Africa, bringing the overall number of laboratory-confirmed cases to 3,755,459. This reflects a 17.8% positivity rate. “The public should exercise caution in interpreting these data as there may be changes in test patterns. An early warning indicator, wastewater detection surveillance, shows an increase in Gauteng”, comments NICD Executive Director, Prof Adrian Puren. He adds that there is currently no evidence that the Omicron variant of concern is being displaced as the dominant circulating variant.

There may be a backlog of COVID-19 mortality cases reported due to the current audit effort by the National Department of Health (NDoH). Today, the NDoH reports 10 fatalities, with 1 occurring during the last 24 – 48 hours. This puts the overall number of fatalities to 100,286.

24,288,173 tests have been conducted in both public and private sectors as per the table below.

VACCINE UPDATE

The NICD recommends that persons who have not been vaccinated against COVID-19 be vaccinated and get booster shots as needed. Persons over the age of 65, those at risk of serious disease, and those eligible for boosters should take advantage of the shorter time to immunization.

“Respiratory syncytial virus (RSV) season is ongoing and we have noticed sporadic cases of influenza. Influenza vaccination is therefore strongly encouraged for all high-risk groups (healthcare workers in the workplace, people age 65 and older, women who are pregnant and individuals with co-morbidities such as heart disease, high blood pressure, chronic respiratory diseases, cancer  and diabetes)”, stresses Dr Sibongile Walaza, Medical Epidemiologist at the Centre for Respiratory Diseases and Meningitis.
