LONDON: So much for the sanctity of national sovereignty. Viruses do not respect state frontiers; nor do they pay heed to the anti-immigrant banners waved aloft by a generation of populist leaders.
The worldwide spread of coronavirus has instead given eloquent expression to the stubborn fact of international interdependence.
Donald Trumps America First policy has offered scant protection against the outbreak. This is also the president who has been pressing for cuts in US funding for the World Health Organization, the UN body coordinating the international response.
All in all, Mr Trump has been flat-footed in his attempt to the dismiss the crisis as “a problem thats going to go away”.
Until this week Boris Johnson was striking the same insouciant pose. The prime minister is busy severing Britains ties with the EU. Brexit will not keep the virus at bay.
Mr Trumps wall along the US-Mexican border and Mr Johnsons promise to “take back control” from the EU are turning out to be expensive acts of powerlessness.
Mr Johnson has been lucky. He has been rescued so far by the intelligent planning and presentation of his health minister, Matt Hancock. Mr Trump may well be in deeper trouble.
A MEDICAL AND ECONOMIC EMERGENCY
The virus has reached more than 60 countries. It is now impossible to track the source of each infection. Britains National Health Service has classed the outbreak as the highest level of medical emergency.
The evidence so far suggests the mortality rate will turn out to be low — below 1 per cent — but health systems in many nations could become overwhelmed.
The economic consequences are obvious enough. A simultaneous shock to supply (all those closed Chinese factories) and to demand (safer to stay at home than to go shopping) will seriously damage growth.
The OECD says a long and severe outbreak could halve its forecast global growth rate for 2020 to 1.5 per cent. Interest rate cuts such as that by the US Federal Reserve will have only a limited countervailing impact. Governments must also be ready to loosen fiscal policies.
Whether slowdown turns to recession will depend on how fast and far the virus spreads during coming months. In countries where it takes hold, the focus of governments will turn quickly from the present containment effort to one of delay and mitigation, in the hope that summer weather in the northern hemisphere will slow it down.

Scientists are unsure of how effective this strategy will prove and doubtful of producing a vaccine before next winter.
A POLITICAL MINEFIELD
The result is a minefield for politicians. If the Covid-19 epidemic follows the presumed course, there will be some loud explosions. Such emergencies stir strong public emotions. Everyone knows that the first duty of the state is to safeguard the security of its citizens.
Governments cannot be blamed for the virus, but the way they respond to the crisis will never be more closely scrutinised. Perceptions will often count for as much as reality.
Getting it right in such circumstances is not easy. The politicians are flying blind. The worse case scenarios of the epidemiologists are just that; the risk is that they are seen as forecasts.
In 2009, the British government predicted that up to 65,000 UK citizens could be killed by that years swine flu pandemic. In the event the official figure was less than 500, though some later estimates suggested it might be a little higher.
The line between intelligent precaution and fuelling a panic is a fine one. The authorities in the Italian region of Lombardy, where coronavirus has taken serious hold, have been accused by the Rome government of excessive testing of potential victims.
In Japan, there is more than a suspicion that political leaders have imposed severe restrictions on tests so as to conceal the extent to which the virus has spread.
HONESTY: WHAT PEOPLE APPRECIATE
The politicians best weapon is honesty. Past experience says voters are perfectly prepared to live with the hardship and loss caused by what many might call an act of God.
But they also expect political leaders to show grip, competence and candour. It is easy to see why Mr Trump and Mr Johnson may find themselves in trouble.
Coronavirus is blind, however, between elected politicians and autocrats. Not so long ago, President Xi Jinping was being styled as Chinas emperor-for-life.
