The New York Times is releasing a series of data files with cumulative counts of coronavirus cases in the United States, at the state and county level, over time. We are compiling this time series data from state and local governments and health departments in an attempt to provide a complete record of the ongoing outbreak.

Since late January, The Times has tracked cases of coronavirus in real time as they were identified after testing. Because of the widespread shortage of testing, however, the data is necessarily limited in the picture it presents of the outbreak.

We have used this data to power our maps and reporting tracking the outbreak, and it is now being made available to the public in response to requests from researchers, scientists and government officials who would like access to the data to better understand the outbreak.

The data begins with the first reported coronavirus case in Washington State on Jan. 21, 2020. We will publish regular updates to the data in this repository.

In Los Angeles County, methamphetamine accounted for the highest share of overdose deaths among people experiencing homelessness (PEH) in the 12 months before and after the COVID-19 pandemic onset, contributing to approximately three-quarters of all overdose deaths in both years. Fentanyl ranked as the second leading cause of overdose death in both periods, but showed the largest increase in its contribution over the analyzed timeframe. This statistic depicts the percentage of deaths among people experiencing homelessness by overdose pre- and post-COVID-19 pandemic in Los Angeles County, by drug type.

The COVID-19 pandemic has undoubtedly impacted everyone around the globe. In 2020, many countries entered into a lockdown, transforming daily lifestyles into isolation. The SARS-CoV-2 virus that causes the disease COVID-19 slowly spread to different regions of the world, and the first cases of COVID-19 infection in Los Angeles County, California, were documented in mid-January 2020. In March 2020, Governor Gavin Newsom of California declared a state of emergency and implemented a stay-at-home order (1). Therefore,

people were quarantined at home, and many “non- essential” businesses were closed, including schools.

With no cure available and hospitals reaching maximum capacity, scientists raced to develop vaccines to immunize individuals against the virus. Meanwhile, wastewater technicians began collecting wastewater samples to monitor the presence of the SARS-CoV-2 virus shed from infected residents. We hypothesized that the presence of SARS-CoV-2 RNA in LA County wastewater would decrease as localized vaccination rates increased. Here, we describe a meta-analysis comparing two data sets; the vaccination progression data in Los Angeles County, and the wastewater surveillance PCR

In Los Angeles County, the number of deaths among people experiencing homelessness (PEH) had an overall increase when comparing the 12 months pre- and post-COVID-19. Among the leading death causes, drug overdose reported the biggest increase of 78 percent. Additionally, COVID-19 was the third leading cause of death from April 1, 2020 to March 31, 2021, resulting in 179 deaths during that time. This statistic depicts the number of deaths among people experiencing homelessness, 12 months pre- and post-COVID-19 pandemic, in Los Angeles County, by cause of death.

Wildlife strongly alter behavior in response to human disturbance; however, fundamental questions remain regarding the influence of human infrastructure and activity on animal movement. The Covid-19 pandemic created a natural experiment providing an opportunity to evaluate wildlife movement during a period of greatly reduced human activity. Speculation in scientific reviews and the media suggested that wildlife might be increasing movement and colonizing urban landscapes during pandemic slowdowns. However, theory predicts that animals should move and use space as efficiently as possible, suggesting that movement might actually be reduced relative to decreased human activity.

We quantified space use, movement, and resource-selection of 12 GPS-collared mountain lions (8 females, 4 males) occupying parklands in greater Los Angeles during the Spring 2020 California stay-at-home order when human activity was far below normal. We also tested the hypothesis that reduced traffic on Los Angeles area roadways increased permeability of these barriers to animal movement.

Contrary to expectations that wildlife roamed more widely during pandemic shutdowns, resident mountain lions used smaller areas and moved shorter distances relative to their historical behavior in greater Los Angeles. They also relaxed avoidance of anthropogenic landscape features such as trails and development, which likely facilitated increased traveling efficiency. However, there was no detectable change in road-crossing, despite reduced traffic volume.

Our results support the theoretical prediction that animals maximize movement efficiency and suggest that carnivores incur energetic costs while avoiding humans. While mountain lions may restrict movement at the landscape-level relative to barriers, they appear to increase distances moved at finer scales when avoiding human activity - highlighting the scale-dependent nature of animal responses to human disturbance.

Avoiding humans can reduce direct mortality of large carnivores and is often suggested to be an important mechanism promoting coexistence in shared landscapes. However, energetic costs incurred by increased movement and space-use while avoiding human activity may have important consequences for population viability, predator-prey interactions, community structure, and human-wildlife conflict. Management providing sufficient wild prey and education regarding best practices for protection of domestic animals are important for conserving large carnivores in human-dominated landscapes.

Death rate has been age-adjusted by the 2000 U.S. standard populaton. All-cause mortality is an important measure of community health. All-cause mortality is heavily driven by the social determinants of health, with significant inequities observed by race and ethnicity and socioeconomic status. Black residents have consistently experienced the highest all-cause mortality rate compared to other racial and ethnic groups. During the COVID-19 pandemic, Latino residents also experienced a sharp increase in their all-cause mortality rate compared to White residents, demonstrating a reversal in the previously observed mortality advantage, in which Latino individuals historically had higher life expectancy and lower mortality than White individuals despite having lower socioeconomic status on average. The disproportionately high all-cause mortality rates observed among Black and Latino residents, especially since the onset of the COVID-19 pandemic, are due to differences in social and economic conditions and opportunities that unfairly place these groups at higher risk of developing and dying from a wide range of health conditions, including COVID-19.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

During the 2023 fiscal year, the number of passengers transported by the Los Angeles County Metropolitan Transportation Authority (LACMTA) network amounted to some 270 million, a year-over-year increase of around 6.6 percent, after figures plummeted by 36 percent amid the COVID-19 pandemic in 2021.

During the 2023 fiscal year, the operating revenue of the Los Angeles County Metropolitan Transportation Authority (LACMTA) amounted to approximately 222.5 million U.S. dollars, a significant year-over-year increase of a hundred percent post the COVID-19 pandemic.
