Fever, cough, sore throat and tiredness can be caused by several different viruses. In the Baltic states they spread most from late autumn to early spring, often at the same time. Symptoms alone rarely tell you which virus you have, but a rapid test from one nasal swab can.
Why it matters which virus it is
Knowing the cause helps you decide how long to avoid contact with others, whether to protect higher-risk people at home and whether to contact a doctor. For flu, a doctor may prescribe antiviral medicine, which works best when started within the first two days of illness.
Who is at higher risk
- Babies and young children (especially with RSV)
- People over 65
- Pregnant women
- People with chronic heart, lung or kidney disease, diabetes or weakened immunity
When to test
Test in the first 1–5 days of symptoms, when the amount of virus is highest. If you test too early or too late, the result can be negative even if you are ill. If symptoms continue, repeat the test after 1–2 days.
Which test to choose
| Test | Detects | Result | Price |
|---|---|---|---|
| 5-in-1 | COVID-19, influenza A and B, adenovirus, RSV | 15 min | €5.95 |
| 3-in-1 | COVID-19, influenza A and B | 10 min | €5.25 |
If there are babies or older people at home, choose the 5-in-1 test: RSV and adenovirus are common in children.
5-in-1 test – €5.95 → 3-in-1 test – €5.25 →
When to see a doctor straight away
- Difficulty breathing or shortness of breath
- Chest pain
- High fever lasting more than 3 days
- Confusion or unusual drowsiness
- A baby who refuses to feed or shows signs of dehydration (few wet nappies, crying without tears)
In an emergency, call 112.
Rapid tests are intended for preliminary screening and do not replace a doctor’s consultation.
