Confirmed cases in Australia notified up to 5 April 2020: Notifications = 5,805; Deaths = 33. Notifications in Australia remain predominantly among people with recent overseas travel, with some locally-acquired cases being detected. Most locally-acquired cases are able to be linked back to a confirmed case, with a small portion unable to be epidemiologically link. The distribution of overseas-acquired cases to locally acquired cases varies by jurisdiction. Early indications are that reduction in international travel, domestic movement, social distancing measures and public health action are slowing the spread of the disease. Internationally, cases continue to increase, with high rates of increase observed in the European region and the United States of America. The epidemiology differs from country to country depending not only on the disease, but also on differences in case detection, testing and implemented public health measures.

Confirmed cases in Australia notified up to 12 April 2020: notifications = 6,394; deaths = 46.

The rates of increase have started to slow in several regions, although it is too soon to tell whether this trend will be sustained.

Confirmed cases in Australia notified up to 03 May 2020: notifications = 6,784; deaths = 89. The reduction in international travel and domestic movement, social distancing measures and public health action have likely slowed the spread of COVID-19 in Australia. Currently new notifications in Australia are mostly considered to be locally-acquired with some cases still reported among people with recent overseas travel. Most locally-acquired cases can be linked back to a confirmed case or known cluster, with a small portion unable to be epidemiologically linked to another case. The ratio of overseas-acquired cases to locally-acquired cases varies by jurisdiction. The crude case fatality rate (CFR) in Australia remains low (1.3%) compared to the World Health Organization’s globally-reported rate (7.1%) and to other comparable high-income countries such as the United States of America (5.7%) and the United Kingdom (15.4%). The lower CFR in Australia is likely reflective of high case ascertainment including detection of mild cases. Internationally, cases continue to increase. The rates of increase have started to slow in several regions, although it is too soon to tell whether this trend will be sustained.

Confirmed cases in Australia notified up to 19 April 2020: notifications = 6,606; deaths = 69. The reduction in international travel and domestic movement, social distancing measures and public health action have likely slowed the spread of the disease. Notifications in Australia remain predominantly among people with recent overseas travel, with some locally-acquired cases being detected. Most locally-acquired cases can be linked back to a confirmed case, with a small portion unable to be epidemiologically linked. The distribution of overseas-acquired cases to locally-acquired cases varies by jurisdiction. The crude case fatality rate (CFR) in Australia remains low (1.0%) compared to the World Health Organization’s globally-reported rate (6.8%) and to other comparable high-income countries such as the United States of America (4.7%) and the United Kingdom (13.5%). The low CFR is likely reflective of high case ascertainment including detection of mild cases. High case ascertainment enables public health response and reduction of disease transmission. Internationally, cases continue to increase. The rates of increase have started to slow in several regions, although it is too soon to tell whether this trend will be sustained. Interpretation of international epidemiology should be conducted with caution as it differs from country to country depending not only on the disease dynamics, but also on differences in case detection, testing and implemented public health measures.

Confirmed cases in Australia notified up to 26 April 2020: notifications = 6,711; deaths = 77. The reduction in international travel and domestic movement, social distancing measures and public health action have likely slowed the spread of COVID-19 in Australia. Notifications in Australia remain predominantly among people with recent overseas travel, with some locally-acquired cases being detected. Most locally-acquired cases can be linked back to a confirmed case, with a small portion unable to be epidemiologically linked to another case.

The lower CFR in Australia is likely reflective of high case ascertainment including detection of mild cases. High case ascertainment and prompt identification of contacts enables an effective public health response and a reduction of disease transmission. Internationally, cases continue to increase.

SummaryThe emergence and spread of SARS-CoV-2 lineage B.1.1.7, first detected in the United Kingdom, has become a national public health concern in the United States because of its increased transmissibility. Over 500 COVID-19 cases associated with this variant have been detected since December 2020, but its local establishment and pathways of spread are relatively unknown. Using travel, genomic, and diagnostic testing data, we highlight the primary ports of entry for B.1.1.7 in the US and locations of possible underreporting of B.1.1.7 cases. New York, which receives the most international travel from the UK, is likely one of the key hubs for introductions and domestic spread. Finally, we provide evidence for increased community transmission in several states. Thus, genomic surveillance for B.1.1.7 and other variants urgently needs to be enhanced to better inform the public health response.
