 The Finnish Institute of Occupational Health advices the employees to follow the instructions of the employer in order to avoid infections at workplace. The best way to reduce the infections is to take a vaccination.

When is protection necessary?

Protection is important both for yourself and for your colleagues and family. The best way to protect yourself is to take a vaccination, wash your hands often and properly and use facemasks. Try to keep a distance  to clients and colleagues. When greeting other people do not shake hands. 

Follow  your employer’s guidelines regarding safety, hygiene, personal protective equipment (PPE), face masks and other orders and restrictions. 

Download the App Koronavilkku to your phone.. Through the app, people exposed to the virus can be reached and infection chains can be stopped faster.

See also the regional situation. It can be checked out here (Finnish institute for health and welfare, THL).  

How is coronavirus transmitted?

The novel coronavirus (SARS-CoV-2) spreads by droplets, aerosols in the air. Coronavirus can also be transmitted via contact. Coughing, sneezing and speaking on loud voice may increase the risk of the infection.

Use the Koronavilkku and answer your phone if a covid-19 tracer calls you

  • Download Koronavilkku app to your phone. The Koronavilkku will let you know if you have been exposed to COVID-19.
  • If you have been infected you can inform about the infection anonymously via Koronavilkku. The use of Koronavilkku makes it faster to reach people who  have been exposed to the virus. See the instructions: App Koronavilkku 
  • It is recommended that you also tell your employer if your have been infected. This helps the employer to take care of the safety at the workplace and also fulfill the statutory obligations the employers have.
  • The primary precaution is remote work. If it is not possible to work remotely, other precautions need to be agreed at workplace. The surgical masks can be used especially at the health and social care.


  • Vaccines are the best way to protect yourself from covid-19 and prevent you from infecting others. But even though you are vaccinated you might still get infected so you should follow the instructions for prevention carefully.

  • The rate of vaccinated employees can influence the  restrictions at your workplace.

  • It is good to speak openly about vaccinations at your workplace, because that is the only away the employer will know if the employees have been vaccinated.

What do I do if I suspect I have contracted coronavirus?

  • Make a symptom assessment in the Omaolo service or contact your health care provider. In the feedback from this assessment, you will receive instructions on how to request a test and how urgently you should seek treatment.
  • You can also contact you occupational health care unit or a health centre in order to get information on tests. 
  • Symptoms among coronavirus patients include fever, cough, sore throat, shortness of breath, muscle pain, fatigue, runny nose, nausea, diarhoea. Loss of the sense of smell and/or taste have also been reported as symptoms of a COVID-19 infection.
  • It is not obligatory for the employee to tell information of his/her health conditions for the employer. However it would be important for employer to get information on your covid-19 infection or a suspicion of covid-19 because otherwise it is difficult for the employer to protect other workers.
  • See THL website What are the symptoms of a coronavirus infection?

Follow your employer’s instructions regarding sick leaves

  • Contact your superior and tell them that you are sick. Tell also if you have COVID-19 infection or if you have been exposed to covid-19 n order to help you employer to protect other workers. If your employer wants a certificate from a physician, contact your occupational health services unit or health centre by phone or via the internet.
  • Keep some distance from your family members if possible. If you need to be close to them use face mask if possible. Wash your hands frequently and use your own towel. Clean the door handles, taps and other surfaces often. Wash the cleaning cloths and bedclothes in 90 Celsius degrees programme.
  • Use paper handkerchiefs and throw them away immediately after using them.
  • Do not welcome visitors while you are sick.
