Even in sparsely populated, remote spots, drug-resistant fungal strains are capable of propagating and spreading very quickly, researcher Jianping Xu says.
The pathogen, known as Lodderomyces elongisporus, typically infects immunocompromised adult patients or intravenous drug users, but has now begun to strike premature infants.
Warming temperatures, heavy rainfalls and rising sea levels caused by a changing climate could teach fungi to thrive in new environments.
