As of November 11, 2022, almost 96.8 million confirmed cases of COVID-19 had been reported by the World Health Organization (WHO) for the United States. The pandemic has impacted all 50 states, with vast numbers of cases recorded in California, Texas, and Florida.

The coronavirus in the U.S. The coronavirus hit the United States in mid-March 2020, and cases started to soar at an alarming rate. The country has performed a high number of COVID-19 tests, which is a necessary step to manage the outbreak, but new coronavirus cases in the U.S. have spiked several times since the pandemic began, most notably at the end of 2022. However, restrictions in many states have been eased as new cases have declined.

The origin of the coronavirus In December 2019, officials in Wuhan, China, were the first to report cases of pneumonia with an unknown cause. A new human coronavirus – SARS-CoV-2 – has since been discovered, and COVID-19 is the infectious disease it causes. All available evidence to date suggests that COVID-19 is a zoonotic disease, which means it can spread from animals to humans. The WHO says transmission is likely to have happened through an animal that is handled by humans. Researchers do not support the theory that the virus was developed in a laboratory.

Around 282 thousand new cases of COVID-19 were reported in the United States during the week ending November 11, 2022. Between January 20, 2020 and November 11, 2022 there had been around 96.8 million confirmed cases of COVID-19 with over one million deaths in the U.S. as reported by the World Health Organization.

How did the coronavirus outbreak start? Pneumonia cases with an unknown cause were first reported in the Hubei province of China at the end of December 2019. Patients described symptoms including a fever and difficulty breathing, and early reports suggested no evidence of human-to-human transmission. We now know that a novel coronavirus named SARS-CoV-2 is causing the disease COVID-19. The virus has been characterized as a pandemic and continues to spread from person to person – there have been around 642 million cases worldwide as of November 17, 2022.

The importance of isolation and quarantine In an effort to contain the early spread of the virus, China tightened travel restrictions and enforced isolation measures in the hardest-hit areas. The World Health Organization endorsed this strategy, and countries around the world implemented similar quarantine measures. Staying at home can limit the spread of the virus, and this applies to individuals who are only showing mild symptoms or none at all. Asymptomatic carriers of the virus – those that are experiencing no symptoms – may transmit the virus to people who are at a higher risk of getting very sick.

As of April 26, 2023, among adults 18-29 years, the total number of cases of COVID-19 has reached almost 19.48million. This statistic illustrates the total number of cases of COVID-19 in the United States as of April 26, 2023, by age group.

As of March 10, 2023, the state with the highest number of COVID-19 cases was California. Almost 104 million cases have been reported across the United States, with the states of California, Texas, and Florida reporting the highest numbers.

From an epidemic to a pandemic The World Health Organization declared the COVID-19 outbreak a pandemic on March 11, 2020. The term pandemic refers to multiple outbreaks of an infectious illness threatening multiple parts of the world at the same time. When the transmission is this widespread, it can no longer be traced back to the country where it originated. The number of COVID-19 cases worldwide has now reached over 669 million.

The symptoms and those who are most at risk Most people who contract the virus will suffer only mild symptoms, such as a cough, a cold, or a high temperature. However, in more severe cases, the infection can cause breathing difficulties and even pneumonia. Those at higher risk include older persons and people with pre-existing medical conditions, including diabetes, heart disease, and lung disease. People aged 85 years and older have accounted for around 27 percent of all COVID-19 deaths in the United States, although this age group makes up just two percent of the U.S. population

As of June 13, 2023, there have been almost 768 million cases of coronavirus (COVID-19) worldwide. The disease has impacted almost every country and territory in the world, with the United States confirming around 16 percent of all global cases.

COVID-19: An unprecedented crisis Health systems around the world were initially overwhelmed by the number of coronavirus cases, and even the richest and most prepared countries struggled. In the most vulnerable countries, millions of people lacked access to critical life-saving supplies, such as test kits, face masks, and respirators. However, several vaccines have been approved for use, and more than 13 billion vaccine doses had already been administered worldwide as of March 2023.

The coronavirus in the United Kingdom Over 202 thousand people have died from COVID-19 in the UK, which is the highest number in Europe. The tireless work of the National Health Service (NHS) has been applauded, but the country’s response to the crisis has drawn criticism. The UK was slow to start widespread testing, and the launch of a COVID-19 contact tracing app was delayed by months. However, the UK’s rapid vaccine rollout has been a success story, and around 53.7 million people had received at least one vaccine dose as of July 13, 2022.

In 2022, the number of malaria cases reported in Venezuela amounted to approximately 151,000, down from around 194,000 infections registered a year earlier. After peaking at over 525,000 malaria cases in 2017, malaria infections have been declining in the South American country. That same year, Venezuela accounted for around 28 percent of malaria infections recorded in Latin America.

In the year 2000, there were around 8,770 cases of measles in the Americas. This number had decreased to 375 in 2023. This statistic shows the estimated number of measles cases worldwide in 2000 and 2023, by region.

In 2022, there were 2,265 hepatitis A infections in the United States, a significant decrease from 18,846 cases in 2019. This statistic depicts the number of hepatitis A infections in the U.S. from 2015 to 2022.

In 2022, there were an estimated 5.2 million cases of malaria throughout Southeast Asia. The estimated number of malaria cases in Southeast Asia has dramatically decreased from 2013, when there were thought to be around 13.2 million cases of malaria.

As of May 2, 2023, the outbreak of the coronavirus disease (COVID-19) had been confirmed in almost every country in the world. The virus had infected over 687 million people worldwide, and the number of deaths had reached almost 6.87 million. The most severely affected countries include the U.S., India, and Brazil.

COVID-19: background information COVID-19 is a novel coronavirus that had not previously been identified in humans. The first case was detected in the Hubei province of China at the end of December 2019. The virus is highly transmissible and coughing and sneezing are the most common forms of transmission, which is similar to the outbreak of the SARS coronavirus that began in 2002 and was thought to have spread via cough and sneeze droplets expelled into the air by infected persons.

Naming the coronavirus disease Coronaviruses are a group of viruses that can be transmitted between animals and people, causing illnesses that may range from the common cold to more severe respiratory syndromes. In February 2020, the International Committee on Taxonomy of Viruses and the World Health Organization announced official names for both the virus and the disease it causes: SARS-CoV-2 and COVID-19, respectively. The name of the disease is derived from the words corona, virus, and disease, while the number 19 represents the year that it emerged.

In 2021, there were an estimated 1.92 billion people worldwide who had anemia. This was an increase from 1.5 billion people in 1990. However, the prevalence of anemia deceased from 28.2 percent in 1990 to 24.3 percent in 2021. Anemia is a condition in which a person does not have enough healthy red cells to effectively carry oxygen throughout the body. Factors that increase the risk of anemia include a diet lacking certain vitamins and minerals, such as iron and vitamin B-12, menstruation, pregnancy, and certain chronic conditions like cancer, diabetes, and kidney failure. This statistic shows the number of people with anemia across all ages worldwide in 1990 and 2021.

The number of cholera cases worldwide has fluctuated over the past two decades, but increased significantly in 2017 to around 1.2 million cases. This statistic shows the number of cases of cholera worldwide from 2000 to 2022.

As of April 16, 2020, there were 632,548 total cases of the COVID-19 disease in the United States, with 611,006 of these cases still under investigation.

The first cases in the United States The COVID-19 disease has been reported in approximately 215 countries and territories worldwide. In the United States, the first cases were detected in travelers to the country; person-to-person spread was subsequently reported among close contacts of returned travelers. Cases of community transmission soon followed, meaning the virus was spreading, but it was not known how or where patients became exposed. Widespread testing programs can help to flatten an infection curve, and the United States is among the countries to have performed the most COVID-19 tests.

What happens to the body once infected? Coronaviruses are typically spread through droplets of saliva when an infected person coughs or sneezes. Patients may start showing signs of a fever or cough, but symptoms can quickly increase in severity: coronaviruses are respiratory diseases that attack the lungs and can cause pneumonia. There is no vaccine to protect against the disease; once under attack, patients may require ventilators to support their breathing and strengthen a weakened immune system.

It was estimated that in 2023, around 10.8 million people worldwide developed tuberculosis. That same year, there were around 384,785 cases of mumps. This statistic depicts the number of reported cases of selected infectious diseases worldwide in 2023.

In 2021, there were an estimated 1.78 million new cancer cases in the United States. This statistic shows the number of cases of cancer in the United States from the year 1999 to 2021.

The highest number of reported cases of syphilis in the United States within the period from 1950 and 2023 was reported in 1950 with a figure of 217,558, followed by 2023 with 209,253 cases. This statistic shows the timeline of the number of reported cases of syphilis in the United States for selected years between 1950 to 2023.

In 2023, the Western Pacific region had an estimated 1.75 million cases of malaria. This statistic shows the estimated number of malaria cases worldwide from 2000 to 2023, by WHO region.

Although malaria has become more preventable across the Asia-Pacific region throughout recent years, Papua New Guinea recorded over 750.25 thousand cases of malaria as of 2020. In comparison, Timor-Leste had approximately 14 recorded cases of malaria in 2020.

What is malaria? Malaria is a disease caused by the bite of a mosquito which is infected by the Plasmodium parasite. Malaria is typically rife in hot countries, as the parasite is able to live in these climates. After Africa and the Eastern Mediterranian, Southeast Asia was the region which had the third highest number of malaria cases worldwide in 2020. That year, Southeast Asia also suffered the third highest number of deaths due to malaria, which was significantly higher than the Western Pacific region.

Attempts to tackle the disease Many countries across the Asia Pacific region have increased attempts to tackle malaria, with members of the World Health Organization (WHO) adopting aims a resolution to have eradicated the disease by 2030. Although malaria started to decrease from 2010 in Southeast Asia, the number of cases rose once more in 2015 and 2016. Subsequently, the Southeast Asian region adopted initiatives to lower the rate of infection. As of November 2017, the region made the funding of new technologies to end malaria a priority. Interestingly, the number of malaria cases in Southeast Asia then decreased in 2017, and continued to decline steadily in the following years.

A total of 1,856 cases of malaria were reported in Guatemala in 2022. This represents an increase of around 46 percent compared to the previous year, when malaria infections amounted to 1,273. At the beginning of the decade, there were 7,300 cases of malaria in Guatemala. Since then, malaria cases have declined in the Central American country, with few exceptions in 2013, 2015, and 2021. During the last year depicted, the neighboring country of Mexico reported 244 cases of the disease.

In 2022, over 10.9 million cases of malaria were reported in Ghana. This was a decrease in comparison to the preceding year when nearly 12.1 million cases were registered. The mosquito-causing illness is prevalent in Ghana and is reported as mostly affecting children under the age of five.
