If we open up the international borders before enough of the population is vaccinated, hospitals could become overwhelmed and deaths would be unacceptably high.
The k number tells us whether the spread of a disease is steady or comes in big bursts, with a small proportion of people infecting many others. The latter is know as superspreading.

The good news is Victoria is more likely to reach zero case of community transmission sooner if vaccination rates pick up, even modestly.
COVID-19 cases in Indonesia are rising and are expected to keep doing so for another two weeks until the effects of restrictions and mask mandates are seen.
It may take until the end of the year to get case numbers close to zero, unless more stringent measures are introduced.

Researchers had suspected that chemical hair relaxers might be behind racial disparities in breast cancer diagnoses. A new study narrows in on lye as a possible cause for that link.
Environmentally dangerous dumps, landfills and pulp and paper mills are more likely to be sited in African Nova Scotian and Mi'kmaw communities. These communities suffer from high rates of cancer and respiratory illness.
Black residents of Shelburne, N.S., spent decades living near a dump, worrying about its possible connection to elevated cancer rates. A new study will investigate the dump’s long-term consequences.
