Sweden will face Tunisia in the World Cup opener in Monterrey, Mexico, on June 15.
"Army security guards will be everywhere on the streets, it's like a war," Dominguez says.
The cartels have an iron grip on young, violent people in large parts of Mexico.
"They have calculated that the cartels recruit around 400 young people between the ages of 13 and 20 every week throughout the country," she says, and continues:
"It is also considered one of the largest employers, unfortunately."
She emphasizes that crimes in Mexico are rarely directly targeted at tourists.
"The cartels are usually more interested in their drug smuggling business."
Guadalajara, which is hosting four matches during the World Cup, was the site of the killing of a major cartel leader by Mexican soldiers in February. This sparked violence in the city but is not expected to affect the tournament, according to Dominguez.
"It's not likely, but you never know what they're planning," she says.
"Less control"
The rest of Sweden's group stage matches will be played in Texas, USA - a country marked by political unrest after the war with Iran, but also by controversy around the immigration agency ICE, which is central to the Trump administration's crackdown on undocumented migrants. ICE has been criticized for excessive force, which has led to major protests.
There is still a different type of concern, according to political scientist Fredrik Uggla.
"In the US, people often think of violence as being carried out by lone individuals, crazy people, who commit crimes. It doesn't really feel like what you think of violence in Mexico," says Uggla, and continues:
"People who suddenly start shooting other people happen in the United States every day. And that means there's a lot less control and a lot more crazy people who can do it."
However, acts committed by "crazy people" have also occurred in Mexico recently. In April, a Canadian woman was shot dead at the pyramids in the city of Teotihuacán.
Blue and yellow: "Be prepared"
The national team's security manager, Martin Fredman, believes that they will be well prepared for the World Cup.
"The team is very well taken care of. You are constantly moving in a protected bubble, both in hotels and when traveling. It happens in a well-established system and then the risks are naturally lower," he says.
Fredman develops the situation for Swedish supporters:
"There will be areas, including Monterrey, that you should avoid. But it is also very clearly communicated that as long as you are in the recommended places, it is very safe and secure," he says, continuing:
"You should be aware that when you travel, you should be in control and prepared as much as you can. But I think you need to be if you go to Rhodes or Crete too."
