Saudi Arabia is the country worst-hit by Middle East Respiratory Syndrome coronavirus (MERS-CoV).
The latest deaths occurred between February 27 and March 5, adding to a surge of cases that killed 30 people in February alone.
Six of those deaths were in Riyadh, health ministry data show.
A total of 936 people have been infected with MERS since it was first identified in the kingdom in 2012, and 402 of them have died.
It uses television, radio, print, social media and text messages with the theme "We can stop it."
Earlier efforts relied on media interviews and statements by health officials, and airports displayed posters about how to prevent the virus.
The intensified campaign comes after a mission by the United Nations World Health Organization and other agencies said "efforts to educate professionals and the public are urgently needed."
The WHO has cited the preliminary results of studies indicating that people working with camels are at increased risk of infection from MERS-CoV, and young camels are particularly susceptible.
More than 20 countries have been affected by the virus but most cases have been linked to the Middle East.
