"Starting from Friday morning, all governorates of the West Bank... will be closed for a period of five days," Palestinian government spokesman Ibrahim Melhem said, adding that pharmacies, bakeries and supermarkets were exempt.

The latest data from the Palestinian ministry of health said that as of Wednesday night, a total of 2,686 people had tested positive for COVID-10 since the illness was first recorded in the West Bank, compared with just 1,256 a week ago.

Last week, after the easing of a previous coronavirus lockdown in late May, Palestinian health minister Mai al-Kaila said the territory had entered a second wave of infections "more dangerous than the first".

Most infections were traceable to Palestinians working in Israel or Arab Israeli visitors to the West Bank, Kaila said.

There have been seven deaths from the virus in the territory.

Israel has also recorded a surge, with a cumulative total of 26,021 confirmed cases on Wednesday night, 980 of them in the past 24 hours -- the highest such count yet.

The Palestinian Authority imposed a full West Bank lockdown after the first coronavirus cases were identified on 5 March, lifting it at the end of May.

A public health state of emergency was reimposed for 30 days from early June.  

Bethlehem was closed from Monday morning after a major spike in COVID-19 infections.

The cities of Hebron and Nablus were also already under lockdown.

Tens of thousands of West Bank Palestinians travel to work in Israel as day laborers and Palestinian prime minister Mohammed Shtayyeh has urged them to self-isolate for 14 days.

Those who are temporarily staying in Israel have been asked not to return home for the time being.

Arab Israelis -- descendants of Palestinians who remained on their land after the creation of Israel in 1948 -- have also been asked to avoid visiting.
