Quick Answer:
Singapore is seeing a fresh wave of COVID-19 infections. If you have been hearing more about COVID-19 lately, you are not alone — and you are right to pay attention.
Here is everything you need to know, based on the latest official data from Singapore’s Communicable Diseases Agency (CDA).
What Is Happening With COVID-19 in Singapore Right Now?
According to the CDA’s official statement on 21 May 2026, an estimated 12,700 COVID-19 cases were recorded in the week of 10 to 16 May 2026 — up from 8,000 cases the week before. That represents a nearly 60% jump in a single week.
Average daily hospitalisations also rose from 56 to 73 patients over the same period. ICU admissions remain low, at approximately one case per day, and public hospitals continue to manage the situation without capacity concerns.
Key figures at a glance:
| Metric | Week of 3–9 May 2026 | Week of 10–16 May 2026 |
|---|---|---|
| Estimated weekly cases | ~8,000 | ~12,700 |
| Avg. daily hospitalisations | 56 | 73 |
| Avg. daily ICU cases | ~1 | ~1 |

Which COVID-19 Variant Is Circulating?
The dominant variant currently circulating in Singapore is NB.1.8.1, a descendant of the JN.1 variant. As of the CDA’s latest update, NB.1.8.1 accounts for more than half of all locally sequenced COVID-19 cases.
The CDA has confirmed that there is no indication that NB.1.8.1 is more transmissible or causes more severe illness compared to previously circulating variants. This is consistent with Singapore’s ongoing experience of COVID-19 as an endemic respiratory disease.
Why Are Cases Going Up?
The CDA has attributed the increase to several contributing factors, with waning population immunity being a key reason. As time passes since the last vaccination or infection, the level of protection in the community naturally decreases — making periodic waves of infection expected, as with other endemic respiratory diseases like influenza.
Who Is Most at Risk?
While most healthy adults typically experience mild to moderate symptoms, certain groups face a higher risk of severe illness. According to the CDA, high-risk individuals include:
- Adults aged 60 years and above, including those in aged care facilities
- Medically vulnerable individuals of any age (those with chronic conditions such as diabetes, heart disease, or weakened immune systems)
- Healthcare workers
- Persons living or working with medically vulnerable individuals
If you or a family member falls into any of these categories, it is important to stay vigilant and take proactive steps.
What Symptoms Should You Watch For?
Common symptoms of COVID-19 (including the NB.1.8.1 variant) include:
- Fever or chills
- Runny nose or nasal congestion
- Sore throat
- Cough
- Headache
- Fatigue
- Shortness of breath
Symptoms can range from mild to moderate in most people. If you develop difficulty breathing, persistent chest pain, confusion, or are unable to stay awake, seek medical attention promptly.
What Does the CDA Recommend?
The CDA has issued clear public health guidance. Here is a summary of what everyone should be doing right now:
Stay protected:
- Ensure your COVID-19 vaccination is up to date. Individuals aged 60 and above, and medically vulnerable individuals aged 6 months and above, are recommended to receive an additional dose if approximately one year has passed since their last dose.
- Other individuals aged 6 months and above who wish to vaccinate may do so voluntarily.
Practice good hygiene:
- Wash hands frequently with soap and water.
- Cover your nose and mouth when coughing or sneezing.
- Wear a mask if you are experiencing symptoms such as a runny nose, sore throat, headache, or fever.
Limit exposure:
- Minimise social interactions and unnecessary travel when you are unwell.
- Avoid visiting vulnerable persons, elderly family members, or healthcare facilities if you have symptoms.
Is the COVID-19 Vaccine Still Effective Against NB.1.8.1?
Yes. The CDA has confirmed that the current COVID-19 vaccine continues to be effective for protection against the NB.1.8.1 variant. COVID-19 vaccinations are available at participating General Practitioner (GP) clinics and Polyclinics island-wide.
Should I Be Worried?
There is no cause for alarm, but there is cause for awareness. Singapore’s health authorities are monitoring the situation closely and hospitals are managing current demand. The rise in cases is consistent with the expected rhythm of endemic respiratory disease.
The most practical approach is to stay informed, act on the guidance above, and seek medical advice early if you are unwell — especially if you are in a high-risk group.
A Note on High-Risk Conditions
If you are managing a chronic health condition — such as diabetes, hypertension, heart disease, or a respiratory condition — COVID-19 can pose a greater risk. Regular monitoring of your chronic conditions, staying vaccinated, and having a clear plan for when you feel unwell are all important parts of managing your health during this period.

Frequently Asked Questions (FAQ)
Can I still get COVID-19 if I am vaccinated?
Yes. Vaccination significantly reduces your risk of severe illness and hospitalisation, but it does not fully prevent infection. Keeping your vaccination up to date remains the most important step you can take.
How is COVID-19 different from the flu right now?
Both are endemic respiratory diseases that cause periodic waves of infection. The key difference is that COVID-19 continues to carry a higher risk of severe illness for elderly and medically vulnerable individuals. Protective measures and vaccination are important for both.
When should I see a doctor for COVID-19 symptoms?
If your symptoms are mild, rest at home, stay hydrated, and isolate to protect others. See a doctor if your symptoms worsen, if you have a high fever lasting more than three days, if you experience breathlessness, or if you are in a high-risk group.
Where can I get vaccinated in Singapore?
COVID-19 vaccinations are available at participating GP clinics and Polyclinics. Ask your GP about your vaccination status and whether you are due for a booster.
Is NB.1.8.1 a new variant of concern?
No. The CDA has confirmed that NB.1.8.1, a descendant of JN.1, shows no indication of being more transmissible or causing more severe disease than previous variants.
