Covid-19 in NZ - Friday’s numbers charted
How is Covid-19 spreading within the country? Newsroom is collating information as it's available to paint a picture of what's happening.
The following charts are based on numbers shared at the daily press conference. These may vary from the full day's numbers released in the Ministry of Health's spreadsheet of case details. This spreadsheet is based on information gathered from Episerv. The date reported for each case in the spreadsheet is not always the same date a positive test result is recorded.
Active cases are people who currently have the virus. The number is lower than the total cases as people who have died, or recovered are not counted as active cases. The number of active cases is important as it's an indication of the load on the health system.
Confirmed cases are cases where there has been a positive laboratory result. Probable cases are those where the symptoms are highly likely to be due to Covid-19 but a test result was negative, or was not performed due to the high likelihood of Covid-19.
The time between a test being performed and a result can differ and can take from 24 hours to 48 hours. The percentage of positive results relates to tests performed on prior days.
The Ministry of Health publishes details of clusters with 10 or more cases. New cases not part of a cluster could be part of smaller clusters, or show the virus has spread beyond known clusters.
A full regional breakdown of Covid-19 cases in easy-to-read charts can be found here.
THE HEALTH SYSTEM
The number of staffed ICU beds in the country is 153. There are additional beds which could be used for ICU patients if needed in wards and other areas. The number of potential beds in an emergency situation across DHBs and private hospitals is estimated at 585.
The following charts are based on current detailed data available for cases. As these details aren't made available until after the daily announcement some numbers may differ from official totals. Newsroom will update charts as detailed case information is made available.
Community transmission is where someone has the virus, but hasn't travelled and hasn't been in contact with a known case. The following graph is taken from published percentages on the Ministry of Health website. Detailed case data shared by the Ministry of Health each day doesn't specify community transmission as an infection cause. For this reason it's not possible to show where community transmission is occurring in the country, or whether a certain age group is most affected.
After New Zealand's borders shut the cause of cases shifted from cases brought in from international travel to cases spread domestically.
