There has been a notable uptick in cold and flu cases recently, alongside the continued presence of Covid-19 throughout the summer months, with expectations of a surge as winter approaches, according to experts.
General Practice New Zealand chairman and Porirua GP, Bryan Betty, observed the rise in respiratory illnesses, typically associated with colder weather. He noted an increase in cases not only among children but also across different age groups. Schools are facing challenges with staffing shortages due to sickness, necessitating class splits and student dismissals.
As winter progresses, Betty anticipates a further rise in cases, particularly in June and July. General practitioners are experiencing heightened pressure, making access to primary care more challenging. To alleviate this strain, the national telehealth service, operational 24/7, offers an alternative for those struggling to reach their GP. Pharmacies are also recommended as an initial point of contact, especially as Healthline call volumes surge during the winter season.
University of Otago epidemiologist, Professor Michael Baker, emphasized that New Zealand is now entering the flu season, typically spanning from May to October. This period sees heightened activity of influenza, RSV, and other seasonal respiratory infections. Currently, there is a noticeable increase in RSV infections and rhinovirus, alongside moderate numbers of influenza cases.
Regarding Covid-19, although cases have been present throughout the summer, Betty highlighted the likelihood of a surge during the winter months. Baker echoed this sentiment, mentioning a recent uptick in cases indicated by wastewater testing and hospitalizations, with a need to monitor if this trend persists. Unlike seasonal infections, Covid-19 cases occur year-round, with significant peaks observed even in summer.
Both Betty and Baker stressed the importance of vaccination against both flu and Covid-19, particularly for at-risk groups. Baker emphasized the need for individuals experiencing respiratory symptoms to self-isolate and wear masks in indoor settings. Health NZ also urged individuals to have a plan in place and to contact their GP for those with pre-existing health conditions, ensuring an adequate supply of medication for the colder months.
