The Ministry of Health (Minsa) confirmed the presence of two cases of seasonal influenza A (H3N2) subclade K in Peru, an infection that has been detected in minors residing in Lima.

Deputy Health Minister Leonardo Rojas made this announcement at a press conference on Monday.

The government official was joined by National Health Institute Executive President Juan Velasco, Medical College of Peru (CMP) Dean Pedro Riega, and Private Clinics Association Chairman Jorge Ruiz on this occasion.

"Yesterday (Sunday), we issued an epidemiological alert on H3N2 influenza directed to all health facilities in order to strengthen epidemiological surveillance at the local level. As a result of the genomic surveillance we have carried out nationwide, two cases of influenza have been detected in two minors," Rojas stated.

He indicated that all surveillance, diagnostic, and monitoring protocols have been activated to contain the spread of the virus.

The measure aims to "protect vulnerable populations: children, older adults, and people who have any type of morbidity, weakened immune systems, cancer, or other illnesses that compromise their defenses."

"What does it mean that we have detected two cases of seasonal influenza A (H3N2)? It means that the surveillance systems are working," Peru's National Center for Epidemiology, Prevention, and Disease Control (CDC) Director, Cesar Munayco, stated.

The official explained that subclade K has been circulating worldwide since August.

Munayco added that the movement of people enables this infection to reach multiple countries swiftly. It originated between the United States and Australia, affecting 32 other countries.

"In the region, our country has been one of the first to register subclade K, along with Costa Rica," he noted.

Is there a risk of an epidemic or pandemic?

"The risk of an epidemic occurring is low because we are not currently in the winter season. We know that respiratory infections increase significantly during winter. We are finishing spring and entering summer," the CDC official said.

"That does not mean we will not have influenza cases—we do have cases—but their spread is low," he noted.

Munayco mentioned that an epidemiological alert has been issued, adding that all measures are being activated to prepare the country for a possible increase in cases, which could occur next winter.

"It is necessary for the population to remain calm. We are not facing any pandemic, unlike what has been circulating on some social media platforms," he clarified.
