PARIS - From the first cases in central China to hopes of a vaccine a year later, here are a dozen key developments in the spread and subsequent fight against COVID-19.

FIRST DEATH

On 31 December 2019, the World Health Organisation (WHO) is alerted to a cluster of pneumonia cases "of unknown cause" in the central Chinese city of Wuhan.

On 7 January 2020, a new coronavirus is identified. Four days later China announces its first death in Wuhan from an illness which will be named COVID-19.

WUHAN CUT OFF

On 23 January, Wuhan is placed under quarantine and cut off from the world. Countries start to repatriate their citizens from China.

On 15 February, France reports the first death confirmed outside Asia, a Chinese tourist.

'PANDEMIC'

By 6 March, more than 100,000 cases have been recorded around the world.

Northern Italy is locked down, quickly followed by the rest of the country.

On 11 March, the WHO says COVID-19 is a pandemic.

Global stock markets crash.

Governments and central banks roll out massive economic support measures.

EUROPE IN LOCKDOWN

Spain (14 March) and France (17 March) order their populations to stay at home. Germany and Britain say people should avoid all social contact. The 27-nation European Union closes its external borders.

OLYMPICS POSTPONED

On 24 March, the Tokyo summer Olympics scheduled for July 2020 are put off to the next year.

The next day the United Nations warns that the pandemic is "threatening the whole of humanity".

HALF OF WORLD CONFINED

Lockdown measures are enforced all around the world.

On 2 April, more than 3.9 billion people - half of the world's population - are forced or called on to confine themselves, according to an AFP count. The same day the threshold of one million cases is crossed.

British Prime Minister Boris Johnson is infected and ends up in intensive care.

ECONOMY ON ITS KNEES

On 29 April, the battered US aircraft manufacturer Boeing slashes 16,000 jobs.

Many other groups including airlines and car manufacturers follow.

HYDROXYCHLOROQUINE ROW

Backed by US President Donald Trump as a potential treatment for COVID-19, malaria drug hydroxychloroquine is judged to have no benefit in a study published in The Lancet on 22 May.

The study is retracted due to problems with the data but on 5 June, a British research group also concludes that the medicine did not help COVID-19 patients at all.

SURGE IN LATIN AMERICA

By 7 June, the death toll reaches more than 400,000.

The surge of cases and deaths in Latin America causes concern.

Brazil becomes the country with the second biggest death toll after the United States. Its president Jair Bolsonaro calls it a "little flu", before himself becoming infected. Fellow COVID-19 skeptic Donald Trump will also get it.

MASKS AND ANTI-MASKS

With cases on the increase, several European countries make mask-wearing compulsory on public transport, in schools and shops, and on the street, starting with the Czech Republic on 18 March.

Anti-mask demonstrations are organised in Berlin, London, Paris, and Rome.

SECOND WAVE

The grim milestone of a million deaths worldwide is passed on 28 September. In October, infections start to spiral in Europe, where many countries order new lockdowns and curfews.

The pandemic also picks up pace in the US, where its handling has become a key issue in the presidential campaign.

VACCINE HOPES

On 9 November, US biotech giant Pfizer and its German partner BioNTech unveil positive results of a vaccine, as the number of official cases passes 50 million.

A week later a similar announcement comes from US firm Moderna, with an AstraZeneca-Oxford University vaccine following fast behind. Authorities hope to begin vaccination campaigns at the end of the year in the US and parts of Europe.
