In a few short but seemingly endless months, an infinitesimal and invisible force has brought even the wealthiest and most resourced countries to their knees.
Going into action means being poised to mobilise surveillance systems to be able to detect and count cases; to put in place ways to effectively isolate cases and quarantine contacts; and to ensure that overarching epidemic prevention measures are implemented and scaled up. Again and again – in 1988, 2003, 2012 and 2016 – well-respected national scientific organisations called for investment in public health. But a report in 2017 noted that public health represented only 2.5% – just $274 per person – of all health spending in the US.
From putting in place systems for the collection of data on health outcomes, researching disease and injury prevention, and detecting, preventing and responding to infectious and non-communicable diseases, public health puts science and data to work at the community level.For example, for each 10% increase in local public health spending in the US, infant deaths decrease 6.
Alarmingly, the US Centers for Disease Control and Prevention has noted that more than 70% of the world remains underprepared to prevent, detect and respond to a public health emergency. At the same time, we must remain cognisant of the cost of these measures. Indeed, we must not ignore the disproportionate impact of Covid-19 on certain populations, whether they be racial/cultural minorities in the US, migrants and displaced people, or the poor around the world. For those with limited resources, population restrictions come at a high price.
