The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in the Chinese city of Wuhan in December 2019; a lockdown in Wuhan and other cities in surrounding Hubei failed to contain the outbreak, and it quickly spread to other parts of mainland China and around the world. The World Health Organization (WHO) declared a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020. Multiple variants of the virus have emerged and become dominant in many countries since 2021, with the Alpha, Beta, Gamma, Delta and Omicron variants being the most virulent. As of 1 December 2021, more than 262 million cases and 5.21 million deaths have been confirmed, making the pandemic one of the deadliest in history. COVID-19 symptoms range from none to life-threatening. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. Transmission of COVID-19 occurs when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but the virus can transmit over longer distances, particularly indoors and in poorly ventilated areas. Transmission can also occur, rarely, via contaminated surfaces or fluids. People remain contagious for up to 20 days, and can spread the virus even if they do not develop symptoms. Several vaccines have been approved and distributed in various countries, which have initiated mass vaccination campaigns since December 2020. Other recommended preventive measures include social distancing, wearing face masks in public, ventilation and air-filtering, covering one's mouth when sneezing or coughing, hand washing, disinfecting surfaces, and quarantining people who have been exposed or are symptomatic. Treatments focus on addressing symptoms, but work is underway to develop medications that inhibit the virus. Authorities worldwide have responded by implementing travel restrictions, lockdowns, business closures, workplace hazard controls, testing protocols, and systems for tracing contacts of the infected. The pandemic has resulted in severe social and economic disruption around the world, including the largest global recession since the Great Depression in the 1930s. It has led to widespread supply shortages exacerbated by panic buying, agricultural disruption, and food shortages. The resultant near-global sustained quarantine saw an unprecedented decrease in the emission of pollutants. Numerous educational institutions and public areas have been partially or fully closed, and many events have been cancelled or postponed. Misinformation has circulated through social media and mass media, and political tensions have been exacerbated. The pandemic has raised issues of racial and geographic discrimination, health equity, and the balance between public health imperatives and individual rights.

The 2010 China floods began in early May 2010. Three hundred and ninety-two people died, and a further 232 people were reported missing as of June 30, 2010, including 57 people in a landslide in Guizhou. Fifty-three of the deaths occurred from the flooding and landslides between May 31 and June 3, and 266 deaths occurred between June 13 and June 29. Four hundred and twenty four people were killed by the end of June, including 42 from the Guizhou landslide; 277 more were killed and 147 left missing in the first two weeks of July, bringing the death toll as of August 5 to 1,072. A landslide in early August in Gansu killed at least 1,471 people and left 294 missing. In total, the flooding and landslides killed at least 3,185 people in China by August 31. More than 230 million people in 28 provinces, municipalities and regions, especially the southern and central provinces and regions of Zhejiang, Fujian, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Chongqing Municipality, Gansu, Sichuan and Guizhou, and the northeastern province of Jilin were affected, while at least 4.66 million people were evacuated because of the risk of flooding and landslides in the latter half of June. By early August, over 12 million people were evacuated, and that number rose to 15.2 million by August 31.Millions lacked drinking water. A total of 1.36 million houses were destroyed and more than 97,200 square kilometres (37,500 sq mi) of crops were inundated, while 8,000 km2 (3,100 sq mi) of farmland had been completely destroyed by the end of June. Dozens of rivers remained flooded, including the Pearl River in Guangdong province, which had been affected by severe drought during the spring as its outflow was severely reduced. The total damages from the floods were roughly 83.8 billion yuan as of June 27, 2010, and over 275 billion yuan (41 billion USD) by August 8. By late August,16.5 million hectares (41 million acres) of farmland were affected by the flooding, while 2.09 million hectares (5.2 million acres) were completely destroyed.In late May 2010, heavy rainfall caused a train derailment in Jiangxi, killing at least 19 people, and the closure of the Shanghai-Kunming railway line for 24 hours due to a landslide. Many major rivers in China, including the Yangtze, Yellow and Songhua Rivers were flooded to danger levels. The Chinese Government allocated over 2.1 billion yuan for rescue and relief work. The Jialing River, Han River and Huai River surged higher than warning levels.
