Objective: To describe the epidemiology of COVID-19 in one region of New Zealand in the context of the national lockdown and provide a reference for comparing infection dynamics and control measures between SARS-Cov-2 strains. Methods: Epidemiological linking and analysis of COVID-19 cases and their close contacts residing in the geographical area served by the Southern District Health Board (SDHB). Results: From 13 March to 5 April 5 2020, 186 cases were laboratory-confirmed with wild-type Sars-Cov-2 in SDHB. Overall, 35·1% of cases were attributable to household transmission, 27·0% to non-household, 25·4% to overseas travel and 12·4% had no known epidemiological links. The highest secondary attack rate was observed in households during lockdown (15·3%, 95%CI 10·4-21·5). The mean serial interval in 50 exclusive infector-infectee pairs was 4·0 days (95%CI 3·2-4·7days), and the mean incubation period was 3.4 days (95%CI 2·7-4·2).
Conclusions: The SARS-CoV-2 incubation period may be shorter than early estimates that were limited by uncertainties in exposure history or small sample sizes.
Implications For Public Health: The continuation of household transmission during lockdown highlights the need for effective home-based quarantine guidance. Our findings of a short incubation period highlight the need to contact trace and isolate as rapidly as possible.

Introduction: Lung cancer, one of the leading causes of death due to neoplasms, requires prompt diagnosis and immediate treatment. The COVID-19 pandemic affected healthcare systems worldwide, having adverse effects on all aspects, particularly on the fate of patients with suspected neoplastic diseases. Limited access to healthcare, disruptions in regular operations (reassigning roles to some wards), postponed hospital admissions, prolonged diagnostic processes, and other factors have collectively led to the phenomenon known as COVID-19 debt.
