What kind of evidence does it require to get a widely used chemical banned? A professor of medicine and former state regulator explains how the case for chlorpyrifos as a threat to public health developed.
Not vaccinating children means living with the knowledge we haven’t done everything possible to ensure they don’t transmit COVID to more vulnerable people.

We owe it to Aboriginal people living near uranium mines to learn more about what’s making them sick.
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.
Research suggests Black women may want to be cautious about heavy use of lye-based chemical hair relaxers.

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.
Even when we immunise all Australians who want to be protected against COVID-19, we’re unlikely to achieve herd immunity through vaccination alone. We need three other measures to open our borders.
The emergence of variants of concern in late 2020 marked a shift in the COVID-19 pandemic.
The Delta variant: What it is, where it came from, why it’s different and whether COVID-19 vaccines can prevent it.
The government says hotel quarantine is ‘serving Australia very well’. But if you look at the leaks as a proportion of COVID-positive returnees, it’s a different story.
Sustained surveillance for disease outbreaks at global hot spots may be the key to preventing the next pandemic.
A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that’s already circulating in our midst.

Only about 1% of the population was vaccinated against COVID when this outbreak started.
You only have to prevent one case, which could have otherwise led to community spread and lockdown, for such a scheme to pay for itself many times over.
The response to the crisis in India speaks to the complexity of public health decision-making.
The amount of risk from overseas arrivals depends not just on Australia’s vaccination rates, but also on the particular circumstances of the country from which people are travelling.
