You understand that more people die every year from the FLU and have for the past forever? these exact same arguments can be made next year to lockdown due to FLU and if we allow that this to go on long-term now it will never end. We will have more old and infirm people dying next year from the Flu and we will have the same shortage of ICU beds because medical advice has changed to now intubate people before they need help breathing as a preventative care measure, unless we then make the argument that their lives don't matter this will start again when last year nobody cared about the flu.
As a premise, it's still too early to discuss SARS-CoV-2 numbers, because we simply don't have the bigger picture yet. So take this with a grain of salt.
Many people die yearly from the flu worldwide, that's correct. The estimate is about 290000 to 650000 people dying from the flu yearly (Influenza A virus in 80% of the cases)
(Iuliano et al. Estimates of global seasonal influenza-associated respiratory mortality: a modelling study. Lancet. 2018;391:1285-300. 10.1016/S0140-6736(17)33293-2).
It's ok to find this scary, but what does it really mean? It means that 0.008% of world population in 2017 died from the flu (mostly in sub-saharian africa, but i digress), and that's what we call a mortality burden: it gives us no data on how this people died, how many required hospitalization or intensive care, or even how many were infected in the first place.
In order to compare SARS-CoV-2 to Seasonal Influenza (which is what you are referring to as the FLU, but it's just a tiny part of the Orthomyxoviridae family) we need at least 3 sets of data: how easily they spread (R0), how easily they get you seriously sick (need of intensive care) and how easily they kill you (mortality/lethality rate).
How easily they spread.
The estimated R0 for the seasonal flu is about
1.3 (Biggerstaff et al. 2014. Estimates Of The Reproduction Number For Seasonal, Pandemic, And Zoonotic Influenza: A Systematic Review Of The Literature.), while estimated R0 for SARS-CoV-2 ranges from
2.4 to 6.5 (Di Wung et al. 2020. The SARS-CoV-2 outbreak: what we know DOI:https://doi.org/10.1016/j.ijid.2020.03.004). This means that SARS-CoV-2 is definitely more contagious (or extremely more contagious; like I already stated, we will need to look back at the numbers when we have the bigger picture). As a reference, R0 is the number of new infections a single infected patient can create.
How often they get serious.
In 2018-2019 italian’s biggest authority in public health (ISS) registered for the whole year 812 serious cases of seasonal flu, which required intensive care (205 of these died). The total number of influenza-like cases where 8072000
(https://www.epicentro.iss.it/ben/2019/luglio-agosto/sorveglianza-integrata-influenza-2018-19). This means only the
0.01% of those 8072000 required intensive care. As for SARS-CoV-2, the number of people currently infected in Italy is (estimated to be) 62013, of these 3612 are in intensive care right now, meaning roughly
6%. If you’re not familiar with what an intensive care unit is, 3612 people is an impressive amount. No, it’s not a regular hospital room/bed, look it up.
How easily they kill you.
It’s way too early to *** SARS-CoV-2 mortalty/lethality rate correctly. We’ll have to discuss about the case-fatality rate, which is good enough for our purpose. The case-fataliy rate is reported to be about 7.2% in Italy and 2.3% in China
(Onder G, Rezza G, Brusaferro S. Case-Fatality Rate and Characteristics of Patients Dying in Relation to COVID-19 in Italy. JAMA. Published online March 23, 2020. doi:10.1001/jama.2020.4683). This is the single data that is more susceptible to bias, since it vastly depends on how many people you identify as SARS-CoV-2 positive (swab or ct scan, the latter having a better sensitivity): in Italy, at the moment, only people who show symptoms compatible with the disease are tested. Actually, not even every symptomatic person is tested (let alone a chest ct scan) unless they get hospitalized. I’m sure you could argue that, based on this, the whole data is meaningless, that we don’t know if it’s really worse than the flu. Well, no seasonal flu epidemic has challenged our hospitals like this in such a short amount of time. I’ve never seen so many bilateral pneumonias and, most importantly, I’ve never heard of undertakers having a month long queue for cremation.
For reference, the mortality rate for seasonal flu in 2017-2018 in the US was about
0.1%(https://www.cdc.gov/flu/about/burden/index.html).
This is real, our people are dying, and for most of them, we don’t know how to help them. They die alone in an hospital bed, surrounded by people fully dressed in what looks like a space suit, who can’t even give them a smile because their face is fully covered. It is heartbreaking.
I hope you found this helpful.
