Abstract
In their study, Jefferies et al. document the impact of an early and intense suppression strategy towards elimination of COVID-19 in New Zealand [1].In the Faroe Islands, an isolated archipelago with 52,500 inhabitants, large scale testing, contact tracing and isolation combined with social distancing lead to an initial successful elimination by late April, despite a relatively high starting point [2].Subsequently, lockdown measures including restrictions on population movement were eased stepwise over several weeks, but on 3 August, after 104 days without local transmission, a second wave hit the Faroes (Fig. 1), similar to the experience in New Zealand [3].De-escalating border restrictions from 15 June (14-day quarantine replaced by a single negative test upon entry) and large private and public gatherings resulted in a COVID-19 outbreak in early August.In response, a massive testing regime was implemented along with rigorous contact tracing and quarantine, but without reinforcing lockdown measures: 42,410 tests were performed from 3 to 24 August (81,558 tests/100,000/pers), 186 positive cases were detected (358/100,000) [4], corresponding to a prevalence of 023%.At this time, a two-step screening protocol for incoming travellers was adopted, recommending a second test on day six after entry similar to the policy implemented in Iceland.Small spikes have been seen mid-September, but the epidemic is under control, despite increasing infection rates in surrounding countries and maintaining borders open.These findings underline the imperative of widespread testing and contact tracing, isolating cases and quarantining their contacts to manage the pandemic, as stated by Jefferies et al. [1].As a result of the timely implemented strategy and quick response to community transmission, the authorities in the Faroe Islands have lifted most movement restrictions enabling the population to engage in social, educational, and cultural activities again, albeit continuously adapting recommended size of gatherings, night life closing hours, and campaigns regarding hygiene and distancing in public areas.The recommended use of facemasks is limited to public transport in the capital area.The experiences of the Faroes and New Zealand show that elimination is possible and realistic, at least in settings where borders can be controlled, but in the absence of a global strategy to eradicate COVID-19, elimination can only be temporary [5].Thus, reactive control measures enhancing response capacity with regard to testing and contact tracing in response to local transmission, and timely escalation and deescalation decisions including social distancing and restricted gatherings, are necessary, even in countries that have eliminated COVID-19.
