COVID numbers are going up, but #flu and #RSV cases continue to drop in #NYC. We still don't have accurate hospitalization numbers for #influenza and #RSVirus here, but it looks like the overall risk of hospitalization and death from acute airborne infectious diseases is dropping.

I'm going to plan for indoor dining and singing, and maybe travel, but as long as this many people are dying and being hospitalized I'll #WearAMask in elevators, trains, doctor's offices, pharmacies and supermarkets!

Cases of #flu and #RSV in #NYC continue to fall, a week or two later than they did last year. Unfortunately, cases and hospitalizatios of #COVID are going up.

I'm going to be pissed if we have a full-blown Spring #COVID19 wave and I have to start moving karaoke online, after months of not singing in person to avoid spreading #influenza and #RSVirus!

While there are meaningful numbers of people being hospitalized for airborne diseases, I #WearAMask in elevators, trains and doctors' offices!

Also frustrated that the #NYC Department of Health and Mental Hygiene still isn't releasing accurate hospitalization counts for #flu and #RSV, but it looks like the case counts are finally down to relatively low levels - below 8,000 for #influenza and below 700 for #rsvirus!

I think I finally feel comfortable hosting karaoke in person next week, for the first time this year!

But as long as there are lots of people suffering and dying, I still #WearAMask in trains, buses and doctors' offices!

It looks like as of the week ending March 1, #RSV cases in #NYC have now been below 1,000 for two weeks. The #flu is below 10,000 cases per week, and hospital visits for #InfluenzaLikeIllness are below 8%!

To be safe, I'm going to skip the live band karaoke I was hoping to attend last week, but I will be hosting karaoke over Zoom on Monday!

My mother and I are still recovering from #rsvirus that was diagnosed in early February. Please #WearAMask in hospitals, doctors' offices and trains!

Due to incomplete data, it turns out the #RSV case count in #NYC was NOT below 1,000 in the week ending February 15. But it's again reported below 1,000 for the week ending February 22.

Cases of #RSVirus and the #flu are clearly trending down. Let's hope they keep dropping, and don't get revised up too far!

In combination with the drop in COVID cases, this suggests that overall March will be safer from respiratory infections. It's stil a good idea to #WearAMask in crowded spaces !

#influenza cases are dropping in #NYC, and #rsv is now down below 1,000 cases a week. Small comfort if, like me, you've been caring for a loved one who's been in and out of hospitals with the #rsvirus for three weeks!

Still, in combination with the plateau in COVID cases, it should be safer to relax precautions - eating indoors more, singing karaoke, maybe taking a plane trip.

But I still #WearAMask in elevators, trains, buses, doctors' offices, hospitals, pharmacies and supermarkets!

We hear these statistics - there are currently 31 people a day hospitalized for #COVID in NYC. What does it mean to be hospitalized for an infectious disease?

Unfortunately, I've recently had a front seat. My mom was hospitalized for #RSV last Friday night. Every case is different, but this can give you an idea...

Commentary by A. Grieve-Smith · What infectious disease hospitalization looks likeTwo weeks ago as I was relaxing before bed, I got a call I dreaded. The EMTs were in my mother's apartment; she had fallen and hit her head. I got dressed, rushed over and joined them in the ambulance, and we set off for the trauma center at Elmhurst Hospital.

#flu was still on the rise in #NYC the week before last, nowhere near the peaks from the past two years, but it looks like the winter #RSV wave peaked in the week ending December 21!

#rsvirus appears to have peaked at the same level as last year, and slightly lower than 2022-2023.

Here's hoping we have relatively mild, quick winter waves for COVID and #influenza and no big outbreaks of pneumonia or bird flu!

For now, I'm avoiding in-person karaoke and I #WearAMask in trains and supermarkets!

Er zijn landen met wel slagvaardig beleid en goed gekozen prioriteiten.

“Landen als Frankrijk en Luxemburg geven de prik al en volgens het RIVM is het aantal ziekenhuisopnames van kinderen met RS in deze landen daadwerkelijk met 80 procent gedaald.”

In #NYC #flu and #RSV case counts continue to climb. There were 2,380 positive #influenza cases in the week ending December 7, well below rates reported in 2022 and 2023 at this time of year.

4,495 positive #rsvirus cases were reported for the week, nearing the 2022 and 2023 peaks.

I still #WearAMask in crowded places like trains, buses and elevators, and wherever there are vulnerable people, like doctors' offices, pharmacies and grocery stores!

This year's #flu and #RSV seasons in #NYC are either late or mild. By this time last year we were seeing over five times as many #influenza cases, and #rsvirus case counts were peaking.

NYC hospitals are reporting 3,436 cases of RSV, more than 2/3 of previous peaks.

These diseases can still be deadly, so let's try to keep the waves small! #WearAMask in confined spaces like elevators and trains, and where there are vulnerable people like doctors' offices, pharmacies and supermarkets!

The November 9 NYC #flu and #rsv report is out, and there's no sign of this year's #influenza wave, but there's definitely an #rsvirus wave, starting about a month later than last year. Hopefully it won't climb as high as last year, or overlap with the winter COVID wave very much!

I have recovered from my ILI, and went for a bike ride today.

Please #MaskUp in confined spaces like elevators and trains, and where there are vulnerable people like doctors' offices, pharmacies and supermarkets!

As I wrote, while there doesn't seem to be much sign of #flu in #NYC #rsv and other #InfluenzaLikeIllness is clearly on the rise in this report, which is almost two weeks old.

There's no sign of a fall/winter COVID wave yet, and #rsvirus counts by themselves aren't very high, but it's something to keep an eye on.

I'm currently home with a mild ILI: no fever, three negative COVID rapid tests.

Please #MaskUp in confined spaces (elevators, trains) and where there are vulnerable people (markets)!

As of October 26 three appears to be a slight increase in #flu and #rsv lab rates in #NYC but the #influenza rate is still below 2022-23 and 2023-24, and the #rsvirus is well below the past three years.

We need to keep monitoring these levels, in order to increase precautions once we have full-blown waves, especially if they coincide with a #COVID wave. Fortunately, we are still well below outbreak thresholds!
