Recovered virus samples spark biosafety questions after Unicamp theft
Brazilian police recovered missing virus samples from Unicamp’s high-security BSL-3 lab—including chikungunya and dengue—after a researcher, Soledad Palameta Miller, was arrested and later released on bail; the case has raised questions about access controls at secure facilities as Brazil plans its first BSL-4 lab nearby, while investigators probe motives and security gaps and regulators say the samples did not pose health risks.
