Nine key Covid symptoms in people who are fully-vaccinated as Ireland in middle of latest wave

The summer wave of Covid-19 is still spreading in Ireland as two highly transmissible subvariants of Omicron take hold.

The rapid spread of these subvariants, BA.4 and BA.5, has largely been the cause of Covid hospitalisation numbers jumping to 1,055 people on Monday, the highest since April.

People have been warned to isolate if they develop any signs or symptoms of Covid such as a fever, a dry cough or fatigue.

However, as the virus continues to change, new symptoms are being brought to light.

Researchers in Norway found that different symptoms are present in vaccinated and unvaccinated individuals and published their findings in medical journal Eurosurveillance.

In people who are vaccinated, a cough, a runny nose and fatigue were found to be the most common symptoms.

However, fever and sneezing were the least common symptoms in fully-vaccinated individuals.

They based their study on an Omicron outbreak that happened at a party in November 2021. Of the 111 guests they interviewed, 89% of those were vaccinated.

They found eight key symptoms in the group of vaccinated party guests who contracted the Omicron variant - these were:

• a persistent cough

• runny nose

• fatigue

• sore throat

• headache

• muscle pain

• fever

• sneezing

Public health experts have included nausea on this list, making it the ninth key symptom for Omicron.

Another sign that has presented itself in those who have Omicron is dizziness or fainting.

If you are displaying any of these signs of Covid, even mild ones, you should self-isolate until 48 hours after your symptoms are mostly or completely gone and wear a face mask if you have to be around other people.

This measure should be followed even if you have completed your first round of Covid vaccination, had a booster, or have had Covid in the past.
