There have been two recent developments regarding U.S. diplomats sickened in Cuba.
New Confirmed Case in Cuba 
The first was on June 21, when the U.S. State Department announced that a 25th U.S. diplomat working at the U.S. Embassy in Havana, Cuba has been sickened by a mysterious illness. This case suggests that “whatever caused the illnesses in late 2016 and the first part of 2017 had started again or was continuing. Yet the U.S. at least privately still states that it has no idea of whom or what may be behind the attacks.
This is one of the two potential cases that the U.S. announced on June 8, as discussed in a previous post. The other individual is still under evaluation.
The official announcement of this development came at the June 21 Department Press Briefing, when spokesperson Heather Nauert stated the following:
- “On June 21st, following a comprehensive medical evaluation, one U.S. diplomat working at the U.S. Embassy Havana was medically confirmed to have experienced health effects similar to those that were reported by members of the U.S. Havana diplomatic community. This is the first medically confirmed case in Havana since August of 2017. The number of Americans now affected is 25. Previously, that number was 24; it is now 25. The health and well-being of our personnel remains our top priority here at the State Department. The investigation into the origin of these symptoms continues, and it is an interagency effort.”
- “The interagency community continues to work diligently to determine the cause of the symptoms, as well as develop mitigation measures. We informed the Cuban Government of this occurrence on May the 29th of this year. The Cuban Government assured us that they will continue to take this seriously and are continuing their investigation. We strongly remind the Cuban Government of its responsibility under the Vienna Convention to protect our diplomats.”
- “Our other employee is still being evaluated at this time, so we don’t have any updates on his or her condition yet.”
- The U.S. has “had conversations with the [Cuban] government, reminding them, of course, of their responsibility under the Vienna Convention. They have pledged to be of assistance in the investigation. . . .”
Other Patients Have Retained Attorney
The other recent development has been at least eight of the 25 U.S. diplomats, intelligence officers and relatives with medical problems from their service in Cuba have hired an attorney, Mark Zaid, to take action to ensure reimbursement for medical expenses.
Zaid, a Washington, D.C. attorney who often represents former/current federal employees who have grievances against the U.S. government, said, “Are they being treated or are they being studied? It’s not entirely clear what is happening.” He added that some of the victims had problems accessing their medical records at the UPenn treatment center because the records are government property. “They are doctors working for the U.S. government.”
Moreover, the attorney added that the uncertainties tied to the cases have placed the government in a predicament because of the mystery not just on the so-called attacks but the injuries experienced. For example, federal employees who have been injured by incidents such as explosions, “the wounds have been specific and concrete, not strange brain and neurological damages. It’s much more complicated.”
