Good day, i visited friends on 5&6 july and one of them received positive covid results on thursday (9 july) . i don't have any symptoms and not feeling sick. should i consult for a test or is it not necessary?

That depends: What was exposure like? Were you close to infected person – less than 2 meters? Were you both wearing masks? Did the person appear ill? Sneeze or cough near you? Interaction less than 10 minutes? In a crowded or poorly ventilated room? – (vs being outdoors). Even if answer is “no” to many of these questions, a direct cough or sneeze can get infect you.
