1973年马来西亚首次发生带有严重临床表现的登革出血热大流行,报告病例共969人,死亡54人。对吉隆坡总医院收治的经临床诊断和实验室确诊的138例病人作了详细研究,68.8%病人有出血表现,18.1%病人有休克。病例主要发生在5～9月,大部分发生在这个国家各州的城镇和城郊。吉隆坡远郊的一个人口密集区 Jinjang 是一个主要的流行点,在那里可以看到高的发病率、重病率和病死率。重症主要见于15岁以下的儿童,而大多数成年患者为轻型表现。华人由于其生活在拥挤区、收入低微、居住环境有大量埃及伊蚊,故华人是主要的罹病者。虽然登革3型是主要的流行型,但在流行期间,所有4个登革型别病毒均被检出。昆虫学资料显示全国埃及伊蚊的高密度,这次流行是由埃及伊蚊传播已无疑问。曾经使用过气雾和喷洒等手段来试图控制媒介的密度。
The first clinical trial of dengue haemorrhagic fever with severe clinical manifestations in Malaysia in 1973 showed that there were 969 reported cases and 54 deaths. A total of 138 clinically diagnosed and diagnosed patients admitted to the General Hospital of Kuala Lumpur were studied in detail. 68.8% had bleeding and 18.1% had shock. The majority of cases occurred between May and September, most of which took place in the towns and suburbs of the states of the country. Jinjang, a densely populated area on the outskirts of Kuala Lumpur, is a major pop spot where high rates of morbidity, morbidity and mortality are seen. Critically ill children are mostly found in children under 15 years of age, whereas most adult patients are light-weight. As the Chinese live in congested areas with low incomes and a large population of Egyptian Aedes mosquitoes in their living environment, the Chinese are the major victims. Although dengue type 3 is the predominant epidemic, all 4 dengue viruses were detected during the epidemic. Entomological data show the high density of Aedes aegypti in the whole country. The epidemic is spread by Aedes aegypti mosquitoes no doubt. Attempts have been made to control the density of the media, such as aerosols and sprays.
