The case comes amid a surge in dengue fever in the nation.

1 Zika virus case in e-week 34

The sole Zika case was revealed by the Ministry of Health (MOH) in their weekly infectious disease bulletin.

It records the case in e-week 34 of 2022 — which corresponds to 21 to 27 Aug.

Likewise, the National Environment Agency (NEA) also reported one case during this period, while indicating zero cases in other weeks.

1st Zika virus case since March 2020

Indeed, the Zika case is the first one since March 2020, reported Channel NewsAsia (CNA).

NEA’s website confirmed that this is the only case so far this year.

However, our last large-scale outbreak of Zika was in 2016, when 455 cases across 15 clusters were identified, according to the National Library of Medicine.

Currently, there is no active Zika cluster in Singapore, NEA said.

Zika virus spread via mosquitoes

Thus, Zika can be prevented by taking the usual anti-dengue measures like eliminating mosquito breeding habitats.

When infected, Zika sufferers may show symptoms like fever, rash, joint pain, muscle pain, headache and red eyes.

Rare serious conditions like neurological complications and foetal abnormalities have also been reported.

However, only about one in five infections are symptomatic.

Surge in dengue cases

Unfortunately, Zika has returned as Singapore is experiencing an ongoing surge in dengue cases.

During the period that the Zika case emerged (e-week 34), 666 dengue cases were also reported.

That brings the total number of cases so far in 2022 to 25,591.

404 cases have also been confirmed in the five days from 28 Aug to 1 Sep.

Though weekly case numbers have gone down since earlier this year, we’re less than 10,000 cases short of beating 2020’s record of 35,315 cases for the whole year.

In 2021, only 5,258 dengue cases were reported.
