New cases per capita

The timing of outbreaks in counties in the New York metro area has varied. Some counties such as Rockland, Westchester, and Nassau had severe first waves in spring 2020. By contrast, other counties such as New Haven, Fairfield, Litchfield, had relatively mild first waves in the spring and more severe second waves in fall 2020. The chart below shows the number of cases per 100,000 residents from March 2020 through the present in each county.

Cases in school

Most recent data: Jan 21, 2021

Since many schools in Westchester reopened for in-person learning in September, students and teachers have tested positive for coronavirus, which has led to some schools moving to remote-only learning temporarily. But in general, schools do not appear to be a major site of transmission. Since Sept 8, there have been 3,009 cases identified in students, teachers, and staff. This is 6% of all cases reported in Westchester during that time period.

The school district with the most reported cases is Ossining School District. There have been 207 positive tests reported of on-site students, teachers, and staff. The district with the second most reported cases is Mamaroneck School District with 192 cases.

In the last 14 days, the school with the most new on-site cases (students, teachers, staff combined) is Hackley School in Tarrytown with 31 cases. Somers Senior High School in Lincolndale has reported 23 new cases in the last 14 days.

New York State micro-clusters

Most recent data: Jan 20, 2021

Governor Cuomo announced a “micro-cluster strategy” in October 2020, in which small geographic areas are targeted with enhanced restrictions on gatherings, indoor dining, and other activities. Yellow, orange, and red zones have different restriction and the clusters are determined using a combination of test positivity rate, hospital admissions, and hospital capacity.

Currently, there are no red zones, one orange zone, and six yellow zones in Westchester County.

Racial disparities

Most recent data: Jan 12, 2021

The Covid-19 pandemic has disproportionately affected communities of color. Nationally, the COIVD Tracking Project estimates that Black people are dying from Covid-19 at 1.7 times the rate of White people. Latino and Native people are also dying more frequently from Covid-19 than white and Asian people. These national racial disparities are also evident in Westchester County. Black people make up 14% of the total population of the county, but have accounted for 19% of Covid-19 deaths.

The disparities are even more stark when taking age into account. Age-adjustment helps to compare groups by adjusting mortality rates for the different age distribution of each population. In Westchester, the median age of the white population is 48, while the median Latino person is 32 years old. The Black population is also younger than the white population, with a median age of 40. Because the white population is significantly older than the Black and Latino population, we would expect the Covid-19 mortality rate of white people to be higher than Black and Latino people.

In fact, we see the opposite. When accounting for the age of the white population in Westchester, 80 out of 100,000 people have died due to Covid-19. By contrast, out of 100,000 Latinos have died and 162 out of 100,000 Black people have died.

The chart below shows both the age-adjusted and crude (un-adjusted) death rates per 100,000 Westchester residents by race and ethnicity.

Deaths in nursing homes

Most recent data: Jan 21, 2021
