How were the past few days in New Zealand and how could it go on?

Coronavirus infections

1,460Apr 241,390Apr 151,520May 4

Using log-linear regression on the data of the previous days, we could infer an increase of reported coronavirus infections in New Zealand of about 0.365% each day. That corresponds to a doubling of the numbers approx. every 190 days.

The graph above and the following table show the course of reported coronavirus infections in New Zealand assuming that the numbers are following an exponential trend without any slowdown.

Deaths by coronavirus

Using log-linear regression on the data of the previous days, we could infer an increase of reported deaths by coronavirus in New Zealand of about 12.4% each day. That corresponds to a doubling of the numbers approx. every 5.9 days.

What is the mortality rate in New Zealand?

Deaths by coronavirus versus statistical death rate

980020101131Apr 15Apr 24)}

In New Zealand, approx. 0.73% of the population die each year. With a population of roughly 4,890,000 people in New Zealand, that corresponds to about 98 deaths per day on the statistical average.

The graph above shows the reported daily deaths by coronavirus in contrast to the statistical number as baseline.

To estimate the mortality rate of coronavirus infections, we need to consider that a reported death already showed up in the reported cases a few days before. It is presumed that this lag is between 7 and 14 days. If we assumed that the lag was about 7 days, the mortality rate in New Zealand would be approx. 1.3%.

The graph aboves shows the mortality depending on different presumed lag.

How could the occupation of intensive care beds in New Zealand develop?

High standardMedium standard2Apr 25

The graph tries to predict the number of required intensive care units in New Zealand. We assume the following:

  • The exponential trend of the past few days has continued and reported cases are active for around 12 days. 2% of active cases are so critical that an intensive care bed is required.
  • High standard: There are 30 intensive care beds per 100,000 inhabitants (1,470 total).
  • Medium standard: There are 15 intensive care beds per 100,000 inhabitants (733 total).

How can I protect myself and others?

The German Federal Ministry of Health recommends:

  • Keep the greatest possible distance when coughing or sneezing - it is best to turn away.
  • Sneeze into the crook of the arm or a handkerchief, which you can then dispose of.
  • Avoid touching when greeting other people and wash your hands regularly and thoroughly with soap and water for at least 20 seconds.
