Activity levels in #Ireland are fast approaching pre-pandemic levels, with Google Community Mobility levels of Parks, Residential, Grocery & pharmacy, and Workplace into above-average, non-lockdown levels of mobility.
TomTom is registering levels of congestion close to pre-pandemic 2019 traffic in #Dublin and #Cork, with congestion in #Cork now HIGHER than pre-pandemic 2019 traffic over the weekends.
(tomtom.com/en_gb/traffic-…)
Mobility and congestion returned towards pre-pandemic levels from the full school return on Monday 12 April, with high levels rising over the preceding weekend.

The Covid-19 reproduction number tracks the same form as mobility - the virus requires people to replicate and social contact & mobility to transmit.

The reproduction number in #Ireland is about 0.94, and rising again.
The reproduction number is estimated to be:-

Imperial College: 0.83 (mrc-ide.github.io/covid19-short-…)

LSHTM: 0.87 (epiforecasts.io/covid/posts/gl…)

Harvard: 0.97 (metrics.covid19-analysis.org)
The reproduction number diverges by age in #Ireland, rising most sharply in those aged 0-64 years. Age-group-specific incidence is rising at 1-4 years, 45-54 years and15-24 years.
Incidence is falling fastest in those most vaccinated, over-65 years.
The number of people actively infected remains high, around 3,200 people with confirmed positive tests (and more asymptomatic / untested). The fall in incidence and active cases is very slow.
Following the current trend in incidence in #Ireland, with the current relatively high reproduction number, we would reach the lockdown exit target of 100 cases per day in the 2nd week of August.
Realistically, this will be a summer of outbreaks and rolling restrictions.
A number of counties in #Ireland have moved into (and out of) the Green and Amber levels, and may not hold their relatively Covid-free status without additional restrictions to preserve their ability to open more activity.
If we recognise social contact and mobility as a limited budget, we are not necessarily spending it well. After essential expenditure on high-social-contact activities like medical care, public transport and education, we seem *very* active but *without* economic activity.

Caution meets wind.

Baseline NPHET modelling predicts a substantial rise in case in the next few months. Upper end predictions are for thousands of cases per day.

Vaccination rollout (18% of over 65s so far) will have little impact on illness and death in the short term.
"Our health system remains extremely fragile & health care workforce is exhausted following the most recent wave of infection. The number of COVID-19 patients in hospital & critical care remains high & in the case of critical care, at levels greater than peak of the 2nd wave."
"The high starting point of 600 cases per day means that case numbers rise rapidly to over 2,000 per day within 4 weeks."

Giving away money inflates property prices and harms communities. The "Rural Development Policy 2021-2025" has the potential to positively support town and rural development, or to do great harm.

Read it and take control.

"Allowing people to live and work in their own communities" is the OPPOSITE of (financially) encouraging "remote workers to come and work in rural Ireland". Both are stated as goals.
rte.ie/news/ireland/2…
Which will prevail?

"support the retention of skilled people in rural areas as well as attracting mobile talent to rural areas."

OR

"funding local authorities to market their areas to attract remote workers."

NPHET, 15 October:
"Were Re to be reduced to 0.5 for 3 weeks, daily cases would reduce to 250-300/day. HOWEVER, releasing measures at that point would likely re-escalation in disease trajectory, such that 1,000 cases/day would be expected by mid-December."
gov.ie/en/collection/…
NPHET, 15 October:
"Were Re to be reduced to 0.5 for SIX [instead of THREE week lockdown] weeks, case numbers would be reduced to 50-100/day, following which release of all measures (Re returning to 1.4) would result in cases not going over 300/day until early January 2021"
The reproduction number R is tied to neighbours - e.g. UK, Spain, France & Germany are largest travel links - but #Ireland imposed lockdown earlier, in October, reducing R moderatly and reducing transmission substantially. R compounds over time, small changes have large impact.

During the next few weeks we can expect, at a minimum, 85,000 cases of coronavirus infection in #Ireland, 6,000 requiring hospital treatment for Covid-19, 700 requiring ICU treatment, and 500-1,000 of whom will die.
Assuming growth is 5.9%/day, continuing 14 days from a new lockdown imposed on 29 December, cases would peak at around 2,200 cases per day, around 10 January. If restrictions from 29 December had the same impact as Level 5 in October then incidence would fall to 90/day in April.
IHME has a more pessimistic projection with cases peaking at 6,800/day on 10 February, with a total of 1,700 deaths - i.e. almost doubling the existing number of deaths from Covid-19 over the winter.

Anyone doubting the value of suppressing coronavirus, Belgium has recorded 18,545 deaths in a population of 11.6 million. One person in every 630 has died from Covid-19.

Estonia recorded just 174 deaths in 1.3 million - just 8% of the Belgian rate.
Countries that have taken STRONG and EARLY measures include Cambodia, Laos, Taiwan, Vietnam, Thailand, China and most of Africa (shown on the same scale here) - with mortality rates 0.5% of the rate recorded by Belgium.

Why are we obstinately rejecting effective suppression?
WHO Step 1: "Mobilize all sectors and communities to ensure that every sector of government and society takes ownership of and participates in the response and in preventing cases through hand hygiene, respiratory etiquette and individual-level physical distancing."

Current trend in daily cases is (at least) a 5.9% per day (49% per week) rise, reaching 1,000 cases per day BEFORE the end of December.
NOTE that NPHET suggested re-imposition of lockdown if cases rose above 400 per day, and we are well over that threshold.
7 Dec: "Ireland could return to lockdown for 3 weeks if cases spike to over 400 per day over Christmas. NPHET has warned government that a “major increase” in socialisation could see 450 infection cases daily being diagnosed before the end of December."
irishmirror.ie/news/irish-new…
Today the data also supports a new structural break at 2 December, a reversal from falling rates to rising rates - close to the end of Level 5 lockdown.
Structural break analysis is an objective means of identifying shifts in gradient or magnitude (Dergiades et al, 2020).
