A pandemic of the novel coronavirus has now killed more than 1 million people worldwide.
Over 35.3 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The criteria for diagnosis -- through clinical means or a lab test -- has varied from country-to-country. Still, the actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.
Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica.
The United States is the worst-affected country, with more than 7.4 million diagnosed cases and at least 210,013 deaths.
California has the most cases of any U.S. state, with more than 833,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 791,000 cases and over 717,000 cases, respectively.
More than 190 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least seven of which are in crucial phase three trials.

NYC public schools in hot spot ZIP codes will be closed
All New York City public schools located in the nine ZIP codes that have been deemed hot spots for rising COVID-19 cases will be closed, New York Gov. Andrew Cuomo announced on Monday.
The nine zip codes, located in Brooklyn and Queens, have seen a recent rise in positive tests -- about 100 public schools will be affected.
Mayor Bill de Blasio sent a proposal on Sunday to the state government requesting the closure of all schools and nonessential businesses in those ZIP codes. Cuomo approved the proposal on Monday.
The schools will be closed beginning Tuesday.

UK reports more than 12,000 new cases
There were 12,594 new cases of COVID-19 and 19 fatalities confirmed in the United Kingdom over the past 24 hours.
The latest daily tally is just short of the records set over the weekend when Public Health England said 15,841 cases between Sept. 25 and Oct. 2 were not included in the United Kingdom's reported daily case counts due to a technical issue. The unreported cases were added retroactively to reach Saturday's count of 12,872 new case and Sunday's 22,961.

Analysis shows cases increasing in 33 US states
An ABC News analysis of COVID-19 trends across all 50 U.S. states as well as Washington, D.C. and Puerto Rico found there were increases in newly confirmed cases over the past two weeks in 33 states plus Puerto Rico.
The seven-day average of new cases in the United States is now the highest it has been since Aug. 22, a concerning national trend as health experts warn that colder temperatures could only exacerbate the spread of the virus.
The analysis also found increases in the daily positivity rate of COVID-19 tests in 25 states, increases in COVID-19 hospitalizations in 35 states plus Washington, D.C., and increases in daily COVID-19 death tolls in 18 states.

Four states -- Nebraska, Montana, South Dakota and Wisconsin -- hit a record number of current COVID-19 hospitalizations in a day. Nine states -- all in the Midwest and West -- have reported a record rise in COVID-19 cases during the last seven days.
Since Sept. 13, the seven-day national average of new cases has increased by nearly 25%.
The trends were all analyzed from data collected and published by the COVID Tracking Project over the past two weeks, using the linear regression trend line of the seven-day moving average.

10% of world population may have been infected, WHO says
The head of emergencies at the World Health Organization said Monday that "best estimates" indicate roughly 1 in 10 people worldwide may have been infected by the novel coronavirus.
"The vast majority of the world remains at risk," Dr. Michael Ryan told a meeting of the WHO's 34-member executive board, noting that the figures vary from rural to urban areas and between different groups.
Based on the current world population, that estimate would amount to more than 760 million infected individuals -- well over the 35 million diagnosed cases of COVID-19 tallied worldwide by both the WHO and Johns Hopkins University.
"We are now heading into a difficult period," Ryan warned.
