Nicaragua and Covid-19

Unlike most countries, Nicaragua has not closed its borders or put any sort of social quarantine in place. For example, all the festivities of Semana Santa took place. And, unlike most countries, Nicaragua has little in the way of coronavirus infections.

One possible explanation is the low infection rate is a lie. The government has been known to "deregulate the truth" but with open borders someone should have figured this out.

https://www.counterpunch.org/2020/04/28/covid19-and-central-america-a-learning-moment/ looks at coronavirus issues in Central America. There is quite a bit about Nicaragua and all indications are that it is not a big issue. Yes, it exists, but at a much lower level than its neighbors.

In an NPR interview with Gioconda Belli, clearly no friend of the Ortega government (https://www.npr.org/2020/04/27/845322525/poet-gioconda-belli-on-nicaragua-in-the-time-of-covid-19) she talks about what she doesn't like but doesn't talk about dead bodies in the streets or any such indication of a pandemic there.

So, what is happening? Why does Nicaragua seem to be relatively immune?
