There is no indication that this photo circulating on social media has any merit.
There is currently no coverage of any such incident happening to presidential candidate Feedinand “Bongbong” Marcos Jr., which points toward the story being false.
The Marcos camp has put out a statement. His spokesperson, Atty. Vic Rodriguez had this to say, “Hindi umiiwas sa handshake si BBM, kundi iniiwas lamang nya ang kanyang kamay na nagkasugat sa braso malapit sa may pulso na tila nagka-impeksyon.” (BBM is not avoiding handshakes, but he is protecting his hand which sustained a wound near the wrist, which now appears to be infected.)

It worth noting that in a viral Tiktok video, Marcos Jr. pulls back his right hand. His alleged injury is on his left.
Given that the Marcos camp has previously claimed a need for safety after assassination plots supposedly discovered on social media platform TikTok, it is highly unlikely that if such an attack on Marcos actually occurred, there would be no press coverage or press release of the incident.
