Background: New Zealand's (NZ) complete absence of community transmission of influenza and respiratory syncytial virus (RSV) after May 2020, likely due to COVID-19 elimination measures, provided a rare opportunity to assess the impact of border restrictions on common respiratory viral infections over the ensuing 2 years.
Methods: We collected the data from multiple surveillance systems, including hospital-based severe acute respiratory infection surveillance, SHIVERS-II, -III and -IV community cohorts for acute respiratory infection (ARI) surveillance, HealthStat sentinel general practice (GP) based influenza-like illness surveillance and SHIVERS-V sentinel GP-based ARI surveillance, SHIVERS-V traveller ARI surveillance and laboratory-based surveillance. We described the data on influenza, RSV and other respiratory viral infections in NZ before, during and after various stages of the COVID related border restrictions.
Aim: To explore the prevalence of ongoing symptoms and laboratory abnormalities in confirmed cases of COVID-19 from the first wave within the Greater Wellington Region, after at least 12 months post infection.
Method: COVID-19 cases were obtained from EpiSurv. Eligible participants electronically completed questionnaires (Overall Health Survey, Patient Health Questionnaire-9 [PHQ-9], Generalised Anxiety Disorder-7 [GAD-7], Pittsburgh Sleep Quality Index, EuroQol 5 Dimension 5 Level [EQ-5D-5L], Fatigue Severity Scale [FSS], WHO Symptom Questionnaire, Modified Medical Research Council Dyspnoea Scale [mMRC Dyspnoea Scale]).
Aims: To review the demographic and clinical characteristics of confirmed COVID-19 cases within the Greater Wellington Region (GWR).
Methods: A retrospective, observational study of all 96 confirmed COVID-19 cases in the GWR. The primary outcome was time taken from onset to complete resolution of symptoms.
Stringent nonpharmaceutical interventions (NPIs) such as lockdowns and border closures are not currently recommended for pandemic influenza control. New Zealand used these NPIs to eliminate coronavirus disease 2019 during its first wave. Using multiple surveillance systems, we observed a parallel and unprecedented reduction of influenza and other respiratory viral infections in 2020.

View Article and Find Full Text PDFCiguatera fish poisoning (CFP) is the most common cause of seafood-toxin poisoning in the world and is most prevalent in tropical and subtropical areas. It causes gastroenteritis but also myriad neurological and cardiovascular symptoms. We present a cluster of CFP that occurred in Wellington Hospital, New Zealand.
View Article and Find Full Text PDFWe describe the first case of food-borne botulism seen in New Zealand for 30 years. Botulism is an important diagnosis to consider in a patient with rapidly progressive descending paralysis and normal sensorium. Early recognition, timely institution of intensive care support and administration of botulism antitoxin are the most important aspects of management.
View Article and Find Full Text PDFAims: We report a cluster of three cases of leptospirosis on a New Zealand dairy farm, with regard to clinical, laboratory, and environmental findings. The cluster is discussed against the annual incidence of leptospirosis in humans and cattle, and the vaccination of cattle as one means of preventing human cases on farms.
Methdos: The three cases were investigated by case interview and review of clinical and laboratory information.
