Editing Pneumonic plague (section)

==Modern outbreaks==
Since 2002, the [[World Health Organization]] (WHO) has reported seven plague outbreaks, though some may go unreported because they often happen in remote areas. Between 1998 and 2009, nearly 24,000 cases have been reported, including about 2,000 deaths, in Africa, Asia, the Americas, and Eastern Europe. Ninety-eight percent of the world's cases occur in Africa.

===Democratic Republic of the Congo===
Two outbreaks occurred in the Democratic Republic of the Congo in 2005 and 2006.<ref name="bertherat11">{{cite journal |doi=10.3201/eid1705.100029|title=Lessons Learned about Pneumonic Plague Diagnosis from 2 Outbreaks, Democratic Republic of the Congo|year=2011|last1=Bertherat|first1=Eric|last2=Thullier|first2=Philippe|last3=Shako|first3=Jean Christophe|last4=England|first4=Kathleen|last5=Koné|first5=Mamadou-Lamine|last6=Arntzen|first6=Lorraine|last7=Tomaso|first7=Herbert|last8=Koyange|first8=Louis|last9=Formenty|first9=Pierre|last10=Ekwanzala|first10=Florent|last11=Crestani|first11=Rosa|last12=Ciglenecki|first12=Isa|last13=Rahalison|first13=Lila|journal=Emerging Infectious Diseases|volume=17|issue=5|pages=778–84|pmid=21529384|pmc=3321750}}</ref> The outbreak in 2005 was only detected by looking back at blood samples.<ref name="bertherat11"/>

===India===

In September 1994, India experienced an outbreak of plague that killed 50 and caused travel to [[New Delhi]] by air to be suspended until the outbreak was brought under control.<ref>Plague Fears Cancel Flights. The Daily Gleaner, 1 October 1994.</ref> The outbreak was feared to be much worse because the plague superficially resembles other common diseases such as influenza and bronchitis; over 200 people that had been quarantined were released when they did not test positive for the plague.<ref>Plague Fears Beginning to Recede.

===China===
A major outbreak of the pneumonic plague occurred in [[Manchuria]] from 1910 to 1911, in what became known as the [[Manchurian plague]], killing around 60,000 people.<ref name="welford09">{{cite journal |last1=Welford |first1=Mark R. |last2=Bossak |first2=Brian H. |last3=Carter |first3=Dee A. |title=Validation of Inverse Seasonal Peak Mortality in Medieval Plagues, Including the Black Death, in Comparison to Modern Yersinia pestis-Variant Diseases |journal=PLOS ONE |date=22 December 2009 |volume=4 |issue=12 |pages=e8401 |doi=10.1371/journal.pone.0008401|pmid=20027294 |pmc=2791870 |bibcode=2009PLoSO...4.8401W |doi-access=free }}</ref> The [[Qing dynasty|Qing court]] dispatched [[Wu Lien-teh]], a doctor educated at [[Cambridge University]], to oversee disease control and treatment efforts.

The [[People's Republic of China]] has eradicated pneumonic plague from most parts of the country, but still reports occasional cases in remote [[Western China|western]] areas, where the disease is carried by [[rat]]s and the [[marmot]]s that live across the [[Himalayan plateau]]. Outbreaks can be caused when a person eats an infected marmot or comes into contact with fleas carried by rats. A 2006 WHO report from an international meeting on plague cited a Chinese government disease expert as saying that most cases of the plague in [[Northwest China|China's northwest]] occur when hunters are contaminated while skinning infected animals.<ref name="China disinfects"/>

The expert said at the time that, due to the region's remoteness, the disease killed more than half the infected people. The report also said that since the 1990s, there was a rise in plague cases in humans—from fewer than 10 in the 1980s to nearly 100 cases in 1996 and 254 in 2000.<ref>Macartney, Jane (3 August 2009).

===Peru===
In August 2010, Peru's health minister Oscar Ugarte announced that an outbreak of plague had killed a 14-year-old boy and had infected at least 31 people in a northern coastal province. The boy died of bubonic plague on 26 July 2010. Ugarte stated that authorities were screening sugar and fish meal exports from [[Ascope Province]], located about 325 miles (520&nbsp;km) northwest of [[Lima]], not far from the popular [[Puerto Chicama|Chicama beach]]. Most of the infections in Peru were bubonic plague, with four cases of pneumonic plague.<ref>[https://www.telegraph.co.uk/news/worldnews/southamerica/peru/7925151/Peru-suffers-deadly-outbreak-of-bubonic-and-pneumonic-plague.html Peru suffers deadly outbreak of bubonic and pneumonic plague] {{webarchive|url=https://web.archive.org/web/20130204210500/http://www.telegraph.co.uk/news/worldnews/southamerica/peru/7925151/Peru-suffers-deadly-outbreak-of-bubonic-and-pneumonic-plague.html |date=4 February 2013 }}, ''The Telegraph'', 3 August 2010.
