New Zealand is currently experiencing its fifth wave of Covid-19 infections, which is causing a significant surge in cases compared to previous waves. According to an epidemiologist, this wave offers a glimpse into the country’s long-term future with the coronavirus. Health officials have reported 7,881 new cases of Covid-19 over the past week, with an increase in probable cases as well.
Hospitalization numbers have also risen, along with the detection of the virus in wastewater surveillance. Data from ESR (Environmental Science and Research) shows a national average of 5.06 million copies of the virus detected per person, per day in wastewater. This is double the number detected just a month ago. These indicators, wastewater detection, and hospitalizations, are at their highest levels since January.
Epidemiologist Professor Michael Baker from Otago University suggests that the peak in hospitalizations during this wave is larger than what was observed in the fourth wave. This may provide insight into what can be expected in the long term, with peaks and troughs of Covid-19 cases.
Although this wave is not expected to reach the height of the wave experienced in 2022, which saw case numbers in the mid-8000s and significant hospitalizations, it is still concerning. There is currently no evidence to suggest the presence of a game-changing new subvariant contributing to the size of this wave. The latest ESR sampling reveals a mix of Omicron subvariants, with the EG.5 or “Eris” type and its relatives being the dominant ones.
As the country approaches Christmas, it remains to be seen whether infection rates will continue to rise. While some regions may be reaching peak levels, others are still experiencing an increase. It is clear that New Zealand is in the midst of a large wave of infections and must respond accordingly.
Moving forward, a national approach to managing peak periods is necessary, according to Professor Baker. This includes promoting booster vaccinations, providing support for self-isolation, and establishing consistent policies for ventilation standards and mask use in healthcare settings. The information gathered from extensive surveillance systems should be acted upon to effectively mitigate the impact of the pandemic.
FAQ
What is the current situation with Covid-19 in New Zealand?
New Zealand is experiencing its fifth wave of Covid-19 infections, which is causing a larger spike in cases compared to previous waves. Health officials have reported 7,881 new cases of Covid-19 over the past week, with an increase in probable cases as well.
Are hospitalization numbers also increasing?
Yes, hospitalization numbers have risen compared to the previous week. The increase in cases is also reflected in the detection of the virus in wastewater surveillance.
What is the outlook for the future in terms of Covid-19 in New Zealand?
This wave provides a glimpse into the long-term future with the coronavirus. While it is not expected to reach the height of the wave experienced in 2022, it indicates that New Zealand can expect peaks and troughs of Covid-19 cases moving forward.
Is there any evidence of a new subvariant contributing to this wave?
Currently, there is no evidence to suggest the presence of a game-changing new subvariant driving the size of this wave. The dominant subvariant detected is the EG.5 or “Eris” type.
What measures should be taken to manage the current wave?
A national approach is necessary to effectively manage peak periods. This includes promoting booster vaccinations, supporting self-isolation, and establishing consistent policies for ventilation standards and mask use in healthcare settings. Acting upon the information gathered from surveillance systems is crucial in mitigating the impact of the pandemic.
