COVID-19 Summary

  • The current wave of COVID-19 transmission in NSW continues to decline. The seven-day hospitalization average is the lowest it has been at any time in 2022. This period of lower activity is likely to continue over the next few weeks.
  • BA.4 and BA.5 Omicron subvariants are currently the dominant (93%) strains.
  • We are closely monitoring S-gene target failure and sequencing data in relation to BA.2 sub-lineages. There are some early suggestions that BA.2.75 infections are increasing. We are also monitoring other emerging variants.
  • PCR testing for COVID-19 has decreased by 11.7% compared to the previous week. The proportion of PCR tests that were positive for COVID-19 is stable at 6%.
  • The number of people in hospital with COVID-19 has decreased by 10.4%. At the end of this week 1,044 people were hospitalised compared to 1,165 at the end of last week. There were 238 people with COVID-19 admitted to hospital and 27 people admitted to ICU this week. Hospital admissions include people with COVID-19 who are admitted for other reasons.
  • There were 75 COVID-19 deaths reported this week. Of these, 10 (13%) had not received three doses of vaccine. One death was of a person aged under 65 years. Deaths may not have occurred in the week in which they were reported.
