Diaspora vloggers-migrants who produce video blogs in the language of their home countries for a transnational diaspora community-have been a largely overlooked group in the studies of social media. This paper focuses on the unique role of Chinese diaspora vloggers during an unprecedented global event - the COVID-19 pandemic.

Australia's response to the coronavirus outbreak has widely been considered to be among the most successful in the world. A bipartisan 'national government' akin to that in wartime, a fairly unified COVID response by the federal and all the state governments, international border closures and quarantine, some of the best coronavirus testing in the world, and widespread public acceptance of physical distancing, all contributed to Australia being able to call itself the 'lucky country' in its successful navigation of the COVID crisis.

Objectives We report on the key clinical predictors of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and present a clinical decision rule that can risk stratify patients for COVID-19. Design, participants and setting A prospective cohort of patients assessed for COVID-19 at a screening clinic in Melbourne, Australia. The primary outcome was a positive COVID-19 test from nasopharyngeal swab. A backwards stepwise logistic regression was used to derive a model of clinical variables predictive of a positive COVID-19 test.

The COVID-19 pandemic has become a widespread public health concern. Restrictions to dental health care services have been implemented to reduce the risk of transmission. Managing dental pain can become difficult and challenging for those undergoing mandatory quarantine for 14 days and as a result are unable able to access dental care. They often need to resort to pharmacological intervention such as antibiotics and analgesics for pain relief. This case report presents a returned overseas traveller to Australia who developed dental pain and significant facial swelling while in quarantine.

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.

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

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 linked.
