Prior to the discovery of the transmitting organism, vector, there were few means for controlling the spread of the disease although the discovery of quinine in treatment had alleviated the problem of treatment. According to one survey, nearly half the world population was at significant risk from malaria in the 19th century with a 10% mortality among those infected.<ref>{{Cite journal|last1=Carter|first1=Richard|last2=Mendis|first2=Kamini N.|date=2002|title=Evolutionary and Historical Aspects of the Burden of Malaria|journal=Clinical Microbiology Reviews|language=en|volume=15|issue=4|pages=564–594|doi=10.1128/CMR.15.4.564-594.2002|issn=0893-8512|pmc=126857|pmid=12364370}}</ref> Ross had already conducted experiments with ''Culex'' (possibly ''C. fatigans'') fed on birds infected with bird malaria ''Protesoma relictum'' (now ''Plasmodium relictum'') in 1894 and noted that they developed in mosquito gut and had surmised that the same may happen in malaria.<ref>{{Cite journal|last=Cox|first=Francis EG|date=2010|title=History of the discovery of the malaria parasites and their vectors|journal=Parasites & Vectors|language=en|volume=3|issue=1|pages=5|doi=10.1186/1756-3305-3-5|issn=1756-3305|pmc=2825508|pmid=20205846|doi-access=free}}</ref> The discovery was made in a small laboratory in Begumpet area of Secunderabad, Hyderabad.

I went to hospital at 7 a.m., examined my patients, and attended to official correspondence; but was much annoyed because my men had failed to bring any more larvae of the dappled-winged mosquitoes, and still more because one of my three remaining ''Anopheles'' had died during the night and had swelled up with decay. After a hurried breakfast at the Mess, I returned to dissect the cadaver (Mosquito 36), but found nothing new in it. I then examined a small ''Stegomyia'', which happened to have been fed on Husein Khan on the same day (the 16th)—Mosquito 87—which was also negative, of course. At about I p.m. I determined to sacrifice the seventh ''Anopheles (A. stephensi)'' of the batch fed on the 16th, Mosquito 38, although my eyesight was already fatigued. Only one more of the batch remained.<ref>{{cite book|page=223|title= Memoirs : with a full account of the great malaria problem and its solution|author=Ross, Ronald|year=1923|publisher=John Murray|place= London|url=https://wellcomecollection.org/works/ckfaqbds/items?canvas=251}}</ref>}}
The London School of Hygiene & Tropical Medicine holds Mosquito Day celebrations every year, including events such as parties and exhibitions. The event was inspired by a tea party honouring Ross held on 20 August 1931 by the Ross Institute and Hospital for Tropical Diseases, which merged with the School in 1934.<ref>{{cite web|title=Health and Science – Abuzz over Malaria on World Mosquito Day|publisher=AlertNet|url=http://www.trust.org/alertnet/blogs/health-and-science/abuzz-over-malaria-on-world-mosquito-day/|date=17 August 2012|archive-url=https://web.archive.org/web/20130421043640/https://www.trust.org/alertnet/blogs/health-and-science/abuzz-over-malaria-on-world-mosquito-day/|archive-date=21 April 2013}}</ref>
