Taiwan reported 3 new measles cases last week [week of 30 Mar 2025],
including 2 imported from Viet Nam and one domestic infection
involving a man living in Taoyuan, with the source of his infection
still under investigation, the Centers for Disease Control (CDC) said
Tuesday [8 Apr 2025].

The domestic case involves a Taiwanese man in his 20s, who developed a
fever and sore throat last Tuesday [1 Apr 2025] and was initially
diagnosed with a common cold at a clinic, CDC physician Lin Yung-ching
said at a regular news conference in Taipei.

“Two days later, a rash appeared on his face, so he went to the
emergency room for treatment,” Lin said, adding that he was diagnosed
with measles on Monday [7 Apr 2025].

CDC spokesman Lo Yi-chun said the Taoyuan man was not a direct contact
of any previously confirmed case, but his housemate had been listed as
a contact of an imported case from Viet Nam, as the housemate and the
infected individual visited the same medical facility.

The Taoyuan man was also present but did not enter the facility, Lo
said, noting that his housemate has not shown any symptoms and had not
been diagnosed with measles as of Tuesday [8 Apr 2025].

Whether there was any overlap in movement between the Taoyuan man and
the imported case, as well as the precise source of infection, remains
under investigation, Lo added.

Three household contacts of the Taoyuan man have been identified and
are under health monitoring until 22 Apr 2025, while 128 individuals
have been listed as contacts of the 2 imported cases, with their
monitoring also set to continue until the same date [22 Apr 2025], he
said.

In the 2 imported cases — a Taiwanese man in his 30s and a Vietnamese
woman in her 20s — they arrived in Taiwan from Viet Nam on 24 and 25
Mar 2025, respectively, according to CDC press materials.

The woman developed a rash on 25 Mar 2025, while the man showed the
same symptom last Thursday [3 Apr 2025]. They were confirmed to have
measles last Tuesday [1 Apr 2025] and this Monday [7 Apr 2025],
respectively, the CDC said.

As of Monday [7 Apr 2025], Taiwan had recorded 22 confirmed measles
cases since the start of 2025, including 8 domestic infections and 14
imported cases — all from Viet Nam — according to a CDC news
release.

Domestic and imported case numbers represent the highest in the same
period for the past 6 years, the CDC added.
