The host city this time is Pyeongchang, South Korea. Opening and closing ceremonies will be housed at PyeongChang Olympic Stadium, a temporary structure with capacity for 35,000 spectators.
The city is about 80 miles (125 kilometers) east of Seoul and about 60 miles south of the Demilitarized Zone that separated North and South Korea. A train between Seoul and Pyeongchang takes about 90 minutes. This will be the second Olympic Games held in South Korea. (Seoul hosted the Summer Olympics in 1988.)
Will North Korea be competing?
The International Olympic Committee announced on January 20, 2018, that North Korea will participate in the Winter Olympics.
North Korea will send 22 athletes who will compete in three sports, according to IOC President Thomas Bach. Athletes from the North and South will also march together under one flag at the opening ceremony for the Games.
For the first time in Olympic history, the two nations will enter a joint women's ice hockey team under the name Korea and represented by the unification flag.
Of the 22 North Korean athletes, 15 will be women and seven will be men, the IOC said. They will be accompanied by 24 coaches and 21 media representatives.
Will Russia be competing?
The short answer, yes. But there is a catch.
Russia was banned in December from taking part in the Games
after the IOC found the country had engaged in "systemic manipulation" of anti-doping rules, though Russian athletes who can prove they are clean will be "invited" to compete under the name "Olympic Athlete from Russia."
Over 1,000 security guards were replaced with military personnel after a norovirus outbreak at Olympic facilities in Pyeongchang. Organizers said 41 security guards suffered a sudden onset of vomiting and diarrhea on Sunday and were taken to a hospital.
Health officials on the Korean Peninsula are also battling two strains of influenza. North Korea is facing a potentially deadly strain of seasonal flu and South Korea has reported a highly contagious strain of bird flu (H5N6) in chicken farms near Seoul.
Health officials have not issued travel restrictions or health warnings.
When will the first medals be awarded?

Which nation is likely to win the most medals?
With some Russian athletes banned by the IOC in December, the top nation from the 2014 Winter Olympics will be absent from the podium. Using the results from key competitions over the past four years, data company Gracenote is predicting
Germany will take home the most medals, followed by Norway and the United States.
What will Team USA be wearing during the opening ceremony?
Ralph Lauren designed Team USA's opening and closing ceremony uniforms
for the sixth time. And unique to this
year's design is the way wearable technology has been seamlessly integrated.

The jackets went through rigorous testing to make sure they were safe before being worn by Olympians.

Are there any new events this year?
There are four events added by the International Olympic Committee for 2018.
On the slopes, athletes will now be able to compete in big air snowboarding and an alpine skiing team event.
On the ice, get ready for mass start speed skating and mixed doubles curling.
Overall, the athletes in Pyeongchang will compete in seven sports -- biathlon, bobsleigh, curling, ice hockey, luge, skating and skiing -- with 15 varied disciplines across all sports.
The competitors each will be hoping to take home at least one of the 102 medals up for grabs.
What do the medals look like?
Created by designer Lee Suk-woo, the medals for these Games feature dynamic diagonal lines and three-dimensional consonants from the Korean alphabet that stretch across the face, according to the official website.
They've been crafted with a texture to resemble tree trunks, symbolizing "the work that has gone into developing Korean culture and the Games themselves," the website said.
Between the bronze, silver and gold medals, the gold weighs the most -- at 586 grams. Overall, 259 sets of medals have been cast for these Games.
South Korea has already managed to overcome a few major hurdles, including construction delays, logistical conflicts and lack of enthusiasm from sponsors.
But early ticket sales have been slow.
Organizers are $267 million short of the $2.4 billion budget needed to operate the Games.
Still, previous host cities that faced similar financial issues saw a large increase in ticket sales during the final months leading up to the Games.
What is the mascot?
The 2018 mascot is a white tiger named Soohorang. The tiger is "closely associated with Korean mythology and culture" and is a "familiar figure in Korean folk tales as a symbol of trust, strength and protection," according to the Games website.
Along with former Olympic figure skater Yuna Kim, honorary ambassadors for these Games include South Korean President Moon Jae-in, former NFL wide receiver Hines Ward and Los Angeles Dodgers baseball pitcher Hyun-jin Ryu.
Another honorary ambassador, South Korean K-pop star Taeyang, is a member of Big Bang, South Korea's biggest boy band. He's also the first K-pop act to be featured on Forbes' prestigious Celebrity 100 list.
