re-open, but schools, bars, restaurants, and barbers were still closed. As at 4 May 2020, when new cases were running around 0.5%, ( persons) per day and consistently falling, it was expected that museums and retailers might reopen from 18 May, while hairdressers, bars and restaurants were expected to reopen fully on 1 June. Regional lockdowns were subsequently imposed as further waves of the virus spread through the country. Rest of Europe As cases of the virus spread to and took hold in more European countries, many followed the earlier examples of China and Italy and began instituting policies of lockdown. Notable among these were Ireland (where schools were closed in mid March for the rest of the month, and limits were set on sizes of meetings), Spain (where a lockdown was announced on 14 March), Czech Republic, Norway, Denmark, Iceland, Poland, Turkey, and France, while the United Kingdom noticeably lagged behind in adopting such measures. As of 18 March 2020, more than 250 million people were in lockdown across Europe. Rest of the world In the immediate context of the start of the pandemic in Wuhan, countries neighbouring or close to China adopted a cautious approach. For example, Sri Lanka, Macau, Hong Kong, Vietnam, Japan, and South Korea had all imposed some degree of lockdown by 19 February. As countries across the world reported escalating case numbers and deaths, more and more countries began to announce travel restrictions and lockdowns. Africa and Latin America were relatively delayed in the spread of the virus, but even on these continents, countries began to impose travel bans and lockdowns. Brazil and Mexico began lockdowns in late February and much of the rest of Latin America followed suit in early March. Much of Africa was on lockdown by the start of April. Kenya, for example, blocked certain international flights and subsequently placed a ban on 'global' meetings. , more than 280 million people, or about 86% of the population, were under some form of lockdown in the United States, 59 million people were in lockdown in South Africa, and 1.3 billion people were in lockdown in India. Self-quarantine Self-quarantine (or self-isolation) is a popular term that emerged during the COVID-19 pandemic, which spread to most countries in 2020. Citizens able to do so were encouraged to stay home to limit the spread of the disease. Health specialists advise that self-quarantine lasts 14 days.
