Stay at home order in NJ for over a month and we are still seeing 3-4k new cases every day??
How is this happening?
Is CV being spread in ways we haven't figured out yet?
I don't know if you are trolling and making crap up. Or if you really just don't understand and are scared. Based on your long-term history as a troll, I'm guessing it is the first. But I will provide a serious answer, just in case it is the second.
Over the past 5 days, NJ has reported about 2100 to 2800 new cases per day. Even with social distancing, you will still have virus spread. Some of it will be institutional (like at long-term care facilities) and some will be because even with a stay-at-home order you still have a lot of essential workers as well as people leaving home for essential services, who are at risk. And of course, you have people who don't follow the stay-at-home order.
It is really hard to track the number of new cases in NJ, because NJ has not performed nearly enough tests to track if infections are increasing or decreasing. Through April 24, the number of positive results was very tightly correlated with the number of tests performed. If more tests were performed, you got proportionally more positive results, Consistently the positive results hovered in the range of 55-60% through April 18, dropping to 45-55% between April 19 and April 24. It is only in the past week that the percent positive has really declined, down to about 30% today.
But the percent positive really needs to get below 10% in order to truly track new cases, which means NJ still needs to conduct about 3 times as many tests -- up to approximately 20,000 to 25,000 per day.
There are a couple of reasons that have been provided as to why there have not been enough testing done. There have been a lack of availability of tests, reagents, testing equipment (such as swabs), PPE, and laboratory capacity to process the tests.
The other big barrier is that CDC testing criteria initially limited tests to those with severe symptoms or known contact with Covid patients (along with healthcare workers, first responders, etc.) While private labs were not compelled to follow CDC requirements, most followed those requirement anyway. It was only on April 27 that the CDC loosened the testing criteria to include others, including those without symptoms, at the discretion of health departments or clinicians.
So without having sufficient testing to determine case growth or decline, you really have to look at other lagging indicators. Hospitalizations is the the indicator that seems to make the most sense, since it easy to count, and doesn't lag as much as ventilator use or death. NJ is not unique in needing to look at hospitalizations to track virus spread, versus looking at new cases reported from test results, which is why federal re-opening guidelines talk about declines in hospitalizations, not declines in new reported cases.
Statewide Hospitalizations in NJ have declined steadily since April 14. In the Northern counties in the state, the decline has been from a high of 5320 on April 14, to a low of 3280 yesterday. In the Central counties (Hunterdon, Somerset, Middlesex, Mercer, Monmouth, Ocean), the decline has been from a high of 2256 on April 13 to a low of 1783 yesterday. The Southern counties have not seen a decline in hospitalizations yet, but growth has potentially flattened, hovering between 899 and 917 over the past 4 days.
