The coronavirus outbreak is impacting many families including Chris Brown.

The travel restrictions imposed to fight the COVID-19 pandemic have kept the singer away from his 4-month-old son, Aeko. According to HollywoodLife, Aeko’s mother, Ammika Harris, traveled to Germany with the couple’s son in January, but Chris is unable to visit because of President Donald Trump’s travel ban. Additionally, Europe has closed its borders banning travelers from outside in order to slow the spread of coronavirus.

“This is not easy on Chris because right now he doesn’t know exactly when he’s going to be able to see his son again,” says a source. “First there was the US travel ban and now the EU has fully closed their borders so he can’t go there and visit for at least a month. It’s rough.”

While Chris misses his son, he is trying to remain optimistic and has been keeping in touch with him thanks to technology. “Chris is doing his best to stay strong,” adds the source. “He FaceTimes with Ammika and he gets to see Aeko that way. And she sends him videos and pictures all day.”

Prior to the outbreak, Ammika had been in Germany for work, where she is modeling for Fashion Nova. Her mother also lives in the country. Ammika has been keeping Chris updated about their son’s life by posting photos on social media.

While U.S. residents are allowed to return from Europe, the process is complicated. American travelers have to fly to one of the 13 pre-approved U.S. airports, where they will be screened. If they test positive for the coronavirus, they won’t be allowed back into the country. If they are allowed back, they will be required to self-quarantine for 14 days.

Meanwhile, Chris has been self-isolated at his home in Tarzana, Calif. All Californians have been directed to stay at home amid the coronavirus outbreak. Earlier this week, he posted a photo of himself in his garage eating a bowl of cereal while in quarantine.
