The field of biosecurity -- aimed at keeping nations safe from natural or human-made pathogens -- has long been eclipsed by cybersecurity and counterterrorism

Covid-19, which is often compared to the flu pandemic of 1918, has been called a once-in-a-generation event. But the outbreak of MERS and SARS in recent years shows just how frequent emerging diseases can occur.

A significant increase in biological containment facilities over the last 30 years also poses a grave risk. There are now more than 50 facilities around the world that are categorized as "Level 4" labs, which contain the deadliest pathogens and require the highest level of safety, and thousands more are designated "Level 3" facilities that contain infectious agents or toxins that may cause potentially lethal infection. While it is highly unlikely that Covid-19 emerged from a laboratory in Wuhan, the pandemic has raised the specter of a possible leak or act of bioterrorism. Containment facilities are an Achilles heel in biosecurity, and these labs, along with those who work there, should be subject to greater international scrutiny.

Millions of people in the UK will need food aid in the coming days, food charities are warning, as the coronavirus outbreak threatens to quickly spiral into a crisis of hunger unless the government acts immediately to reinvent the way we feed ourselves.

Supermarket distribution systems, based on “just in time” supply chains, are struggling to cope with a sudden surge in demand since Covid-19 took hold. The most pressing concern is finding a way to feed the country’s most vulnerable and isolated people.

Anna Taylor, the Food Foundation’s director, said that between 4 million and 7 million people in lower risk categories are also affected by severe food insecurity or loneliness, so having to self-isolate could tip them into crisis.

recent lab studies carried out by the agency at the U.S. Army’s biosecurity laboratory at Fort Detrick, Md.

the novel coronavirus, like many other viruses, does not survive as long when exposed to high amounts of ultraviolet light and warm and humid conditions.

The laboratory results show that increases in temperature, humidity and sunlight all can speed up how fast the virus is destroyed, based on measurements of its half-life when exposed to these elements.

In April 1998, President Bill Clinton read a Richard Preston novel, "The Cobra Event," about a biological attack on the U.S. using a lethal virus that spreads like the common cold.

the result was the first federal government effort to marshal resources in preparation for a pandemic, including the creation of the National Emergency Medical Stockpile, which stowed vaccines and medical gear in secret locations around the country. Bernard was appointed as the first official on the National Security Council whose sole job was to focus on health threats.

Instead, it kicked off a boom-and-bust cycle of pandemic preparedness that persisted into the Trump administration. By many accounts, Trump fell on the bust side of the equation when he fired his top biosecurity adviser, allowed the disbanding of his global health unit, and initially downplayed the coronavirus as it spread across the world.

As a trained epidemiologist with postgraduate qualifications in anthropology, I never thought I’d be a “participant observer” of a pandemic on two continents. But there I was, boomeranging in just five weeks from Australia to New York and back again. From a commitment to science, communitas and mateship here, to defiant disregard for public health, contempt for science and mystical faith in a super-spreader leader in the United States.

On arrival in New York no one stopped me to take my temperature, or to register me, and there was no information about coronavirus exposure, let alone quarantine. The usual madness at ground transport prevailed as passengers arriving from all across the globe hailed taxis or Ubers, or shouted to waiting family – perfect conditions for spreading coronavirus.

in Melbourne, millions of people were struggling under 11 weeks of lockdown, the price that society as a whole paid to suppress the virus, and suppress it they did: as I write no new locally transmitted cases have been recorded in more than a month
