How long is flu b contagious without fever?

My colleague has flu B but no fever. He's still coming to office, saying he's not contagious. Is that true? How long can he spread it even without a fever?

Ah, flu B. Just when you think you're over the fever, the contagion might still be lurking like my pending office emails. Even without fever, you can still pass it on for a few days, typically up to 5-7 days from when symptoms first appeared. It's a real pain, this whole 'being sick' business. Just stay isolated, yaar, no need to be a hero and spread it.

Contagiousness can extend even without fever. Better to isolate for a few extra days to be safe.

Hey, it's natural to want to know when it's safe to be around others. With Flu B, even if your fever is gone, you can still be contagious. Most doctors suggest you're contagious for about 5-7 days from when your symptoms started. Just take it easy, keep your distance for a bit longer, and you'll be good.

It's good that you're asking about this. Even after the fever is gone, flu B can still be spread to others. It's usually safe to assume you might be contagious for about 5 to 7 days from when you first felt sick. Taking precautions is always a kind thing to do.

Even if the fever breaks, the infection is still there, beta. Flu B can be contagious for about 5 to 7 days from when the first symptoms appeared. We usually take ajwain ka pani and rest a lot. But if symptoms are severe or don't improve, always go to the doctor, don't just rely on home remedies.

The body takes its time to heal fully. Even when the fever leaves, the energy of the illness can linger. With Flu B, it is wise to be cautious for about 5-7 days from the start of symptoms. Send positive thoughts to your body for recovery and take care not to pass it on to others. This too shall pass.

My friend had flu B last year and even when his fever was gone, the doc told him he could still spread it for about a week from the day he first felt symptoms. So, it's not just about the fever, man. Better to be careful and not hang out too much for a few days extra.

Dude, it's pretty annoying, but even if the fever bails, you can still be contagious with flu B. My hostel warden said it's usually for about 5 to 7 days from when you first felt sick. So yeah, gotta keep your distance and mask up, even if you feel mostly fine.

Yaar, actually flu B is tricky. Even if fever is gone, you can still pass it on for like 5-7 days from when your symptoms started. So, don't think you're totally clear just because the fever is down. Stay home, chill. Don't be spreading germs, na.
