The Netherlands are basically locked down until 6th of April as a result of the virus.
Labour hours are spread as much as possible and working from home is encouraged as much as possible. All schools are closed, education services are to be provided through the internet. Sporting clubs and events, gyms, musea and concert halls are closed and/or cancelled. Restaurants, cafes and coffeeshops are closed, although take out and delivery services are still available. Any gathering of 100 people or more forbidden. Personnel in critical infrastructure jobs (power, telecom, water, gas, public transport, law enforcement, health care, fire department and the like) are still expected to perform their duties, arrangements have been made to ensure their children are looked after in their schools.
If you are ill, stay at home. If you have flu or cold like symptoms, stay at home.
Luckily, Dutch labour law is pretty clear about when you may be fired from a job as a result of an illness. It's basically a big fat no unless it has rendered you unable to work that job for several years.
