The Central American country, which has had close to 1,000 confirmed cases, has announced strict quarantine measures separating people by gender in an effort to stop the spread of the coronavirus.
From Wednesday, men and women will be able to leave their homes for only two hours at a time, and on different days.
No-one will be allowed to go out on Sundays.
"This absolute quarantine is for nothing more than to save your life," security minister Juan Pino said at a press conference.
In some Colombian towns, people are allowed outside based on the last number of their national ID number.
For example, people in Barrancabermeja with an ID number ending in 0, 7 or 4 are allowed to leave the house on Monday, while those with an ID number ending 1, 8 or 5 can go outside on Tuesday.
Nearby Bolivia is proposing a similar approach.
At one point, Serbia's government introduced a "dog-walking hour" from 20:00 to 21:00 for those in lockdown. But that has now been scrapped, to howls of protest from dog-owners.
One vet said that skipping the evening walk could worsen the condition for the dogs with urinary problems and "aggravate basic hygienic conditions in people's homes".
Unlike its neighbours, Sweden has taken a relaxed attitude when it comes to lockdown measures, despite close to 4,500 confirmed cases there. The government hopes people will behave sensibly, and trusts them to do the right thing.
Gatherings of more than 50 people were banned on Sunday but schools for children under the age of 16 remain open.
Pubs and restaurants can still offer table service and many people are still socialising as normal.
The strategy is dividing opinion both at home and abroad, but only time will tell whether the Swedes' laid-back approach will backfire.
