The data showed Hawke’s Bay had 294 new cases over the week to Monday, still well down on the peaks of about 800 new cases per day in the region early in 2022.
Figures also confirmed 127 people have died with Covid as an underlying or contributory cause of death in Hawke’s Bay as of April 11.
Wastewater testing carried out by the Institute of Environmental Science and Research (ESR) shows that Covid levels remain “low and steady” across the country.
Wastewater testing results in Hawke’s Bay have shown throughout the past year to have been roughly matched with the number of positive RAT tests.
The concentration of Covid in Hawke’s Bay wastewater has decreased by about 75 per cent in that time, from 14.81 million genome copies per person per day in April last year to 3.73 million genome copies per person per day as of April 3 this year.
A report from ESR said that while many sites had recommenced their regular sampling following weather-related impacts in late January and February 2023 from the Auckland flooding and Cyclone Gabrielle, sampling from Napier was still not possible.
The Napier autosampler normally covers 55,000 people in Hawke’s Bay.
Researchers at Covid-19 Modelling Aotearoa found that ending the mandatory seven-day isolation period may cause a bump in infections in the first two months, with a 13 to 25 per cent increase in the total number of Covid hospital admissions and deaths in the subsequent six months.
After four to six months, infections settled to a level that was only slightly higher than if mandatory isolation was maintained, but the additional infections were more likely to be in the vulnerable older population according to the modelling.
“Case isolation reduces community transmission, and removing the case isolation requirements is expected to cause an increase in community transmission,” Dr Emily Harvey, programme co-lead for Covid-19 Modelling Aotearoa, said.
“However, because the policy changes under consideration and the behaviour change in response to any policy changes are not known, the magnitude of this increase is highly uncertain.”
