Measles in Cambodia

Major outbreaks of measles were reported in Cambodia during the 1980’s.  As vaccination uptake steadily increased to levels in excess of 90%, disease incidence in the country is currently similar to the low rates reported by neighboring countries [1,2]  See graphs [3]:

Hand, Foot and Mouth Disease in Singapore

Highest rates of Hand, foot and mouth disease (HFM) in Asia are reported by Singapore and Macao.  In fact, the incidence of HFM in Singapore is even higher than that of the more familiar dengue fever. [1,2]

Lyme Disease in the United Kingdom

The following background data on Lyme disease in the United Kingdom were abstracted from Gideon and the Gideon e-book series.  [1,2] Primary references are available on request.

Time and Place:

Lyme disease is reported from East Anglia, Scotland, Wales, Yorkshire and Northern Ireland.  Highest incidence is associated with popular holiday destinations such as Exmoor, the New Forest, the South Downs, parts of Wiltshire and Berkshire, Thetford Forest, the Lake District, the Yorkshire moors and the Highlands and Islands of Scotland.  “Hot spots” for the disease include the New Forest and the Southwest region.  45% of reports originate in three contiguous counties in southern England:  Hampshire, Wiltshire and Dorset.  This area includes foci in and near the New Forest and Salisbury Plain. Other counties with a relatively high incidence include Devon and Somerset in southwestern England; and Norfolk in East Anglia.


Reporting rates in the United Kingdom are approximately 39% of true incidence (2011).  Case reports peak in the third quarter of each year, which accounts for 48% of all cases.

In the following graphs, I’ve contrasted case numbers and rates per 100,000 in the United Kingdom, with those reported in Ireland and the United States.  Note that highest disease incidence in the United Kingdom is reported from England and Wales;  and highest rates per 100,000 from Scotland.  Reported rates in the United States are approximately 2.5-fold those of Scotland.


Infections due to Borrelia burgdorferi, B. afzelii and B. garinii are identified.

Borrelia valaisiana and B. afzelii have been identified in ticks in Scotland.


Prevalence surveys:

23% of patients referred to an infectious disease unit for suspected Lyme disease (2006 to 2010)
2.3% of dog ticks in the United Kingdom (2009)
4.2% of ticks (Ixodes ricinus) in England (2014 publication)
0.5% of pet-dog ticks (2012 publication)
0% of tick larvae, 2.14% of nymphs and 0% of adults in South London parks (2015 publication)
8.6% of ticks in the Scottish Highlands (both B. afzelii and B. burgdorferi, 1997)
37% of ticks in wooded areas of southern Wales
8.6% of Highland ticks in Scotland (Borrelia burgdorferi, 1997)
5.6% of questing tick nymphs in Scotland (Borrelia burgdorferi, 2012 publication)
11.9% of grey squirrels in Scotland (Sciurus carolinensis, 2015 publication)

Seroprevalence surveys:

2.5% to 4.0% of blood donors in South England
0% to 0.5% of blood donors in the inner-city
25% of forestry workers in endemic areas (1989 publication)
14.3% of farmers in Northern Ireland (1990 publication)
6.5% of individuals in the Scottish Highlands (2004 to 2006)
23% of wild deer in England and Wales (2012 publication)


Grey squirrels (Sciurus carolinensis Gmelin) and pheasants (Phasianus colchicus Linneaus) 18 are important hosts for Ixodes ricinus, and may serve as amplifying hosts for Borrelia burgdorferi in this country.

Seropositive horses are found in most parts of the U.K.

Tick-Borne Encephalitis in the Czech Republic

Rates of Tick-borne encephalitis (TBE) in the Czech Republic are similar to those reported by Austria during the 1970’s. [1,2]   Following the institution of mass vaccination by Austria in 1981, TBE rates decreased to levels experienced in neighboring countries. [3] Enhanced administration of TBE vaccine might also prove effective for the Czech Republic.

Diphtheria in Latvia

Following a regional epidemic during the 1990’s, Latvia has continued to experience a high incidence of diphtheria. [1]  This phenomenon is difficult to explain on the basis of poor vaccine uptake. The following graph compares W.H.O. estimates of vaccination (DPT3) coverage with diphtheria rates reported in Estonia, Latvia and Lithuania. [2]

Malaria in Brunei

Recently ProMED reported that two tourists from Singapore acquired Plasmodium knowlesi malaria in Brunei.

Malaria rates reported by both Brunei and Singapore have been strikingly similar since the 1990’s (see graph below) and Singapore has reported both autochthonous and imported cases of P. knowlesi infection since 2007.  During the 1950’s, Brunei reported low levels of malaria from the interior regions and coast adjacent to mountainous areas.  The predominant infecting species and vector were P. falciparum and Anopheles leucosphyrus, respectively. [1]


Brunei was officially declared “malaria-free” by WHO in 1987.  A single publication reported a case of P. knowlesi malaria in this country in 2013.

Although official sources do not routinely recommend malaria prophylaxis for travelers, the recent report in ProMED suggests careful review of the current status of the disease in Brunei.

Update: Appeared in ProMED

Arthropod-borne Viruses of Senegal

A recent outbreak of suspected viral infection in Kedougou Region ( highlights the complexity of establishing a specific etiological agent in West Africa.  At least twenty arthropod-borne viruses are associated with known or suspected human infection in Senegal.  The following alphabetical list is abstracted from Gideon and the Gideon e-book series [1]   (Primary references are available from Dr. Berger on request)

Bagaza – Bagaza virus has been recovered from mosquitoes in Senegal (Aedes fowleri, Culex neavei, Cx. Poicilipes and Mansonia, Mimomyia hispida, M. lacustris, M. splendens and Aedeomyia africana.

Bangui – Bangui virus was identified in mosquitoes in the Senegal River basin in 1988.

Bunyamwera – Bunyamwera virus has been identified in mosquitoes in the Barkedji region.

Chandipura – Chandipura virus has been identified in mosquitoes in the Barkedji region, and in phlebotomines in the Kedougou district.

Chikungunya – Outbreaks of Chikungunya were reported in Senegal in 1966, 1977, 1982, 1988, 1992, 1996 and 1997.  In 2006, a cluster of six cases in France was reported among travelers returning from Senegal. The virus has been found in a variety of local mosquito species, notably Aedes furcifer-taylori, Ae. luteocephalus, Ae. dalzieli and Stegomyia (Aedes) aegypti. Additional vectors may include Ae. vittatus, Anopheles rufipes and An. coustani.

Dengue – An outbreak of dengue was reported in Senegal during 1927 to 1928; and circulation of the virus was subsequently confirmed in 1974 and during 1999 to 2000. An epizootic among monkeys was reported in 1981; and the first human case was reported in 1983 (from Casamance). Several human and monkey infections were reported in 1990. In 2009, a dengue outbreak (196 cases, 1 fatal) was reported – the first reports of human dengue in Senegal for two decades. Italy reported a case of dengue hemorrhagic fever, imported from Senegal, and cases of dengue fever have been confirmed among French military personnel serving in this country.

Gabek Forest – Gabek Forest virus, a Phlebovirus, has been identified in sandflies (Phlebotomus species) in Senegal (1990 to 1995).

Koutango – Koutango virus (similar to Spondweni virus) has been identified in mosquitoes (Culex neavei) in the Barkedji region.

LeDantec – LeDantec virus is a rhabdovirus which is distinct from the vesicular stomatitis group 1. A single case of infection was reported in Senegal in 1965.

Ngari – Ngari virus has been identified in mosquitoes in the Barkedji region.  Two cases of Ngari virus infection were reported from Dakar,

O’nyong nyong – Although specific data are lacking for Senegal, circulation of O’nyong nyong virus is reported in this region of West Africa.

Rift Valley fever (RVF) – RVF virus was first isolated in West Africa in 1974, from Aedes (Aedimorphus) dalzieli in Senegal. Highest seroprevalence rates are found in the northwest and northcentral regions. Serological studies suggest that the disease was active in Diawara and Bakel (Eastern region) in 1998. Outbreaks were reported among goats, sheep and / or cattle in 2002, 2003, 2013 and 2014.  Carriage by mosquitoes and seroprevalence among sheep in the northern region increased during the 1990’s. Rift Valley virus was identified in mosquitoes in Barkedji in 1993, and re-emerged in 2002. A single isolated case of human Rift Valley fever was confirmed in a school teacher in Kedougou in 2012.

Rift Valley fever virus – seroprevalence surveys:

22.3% of Peul people of the North-central region

15.3% of the population in the Senegal River basin (1995 to 1996)

5% of children born after 1987, vs. 25.3% of the older population in Podor District (1999 publication)

5.2% of individuals in Diawara (1999)

2.9% of small ruminants tested in the Ferlo region (2003)

24.4% of sheep and goats in the Senegal River basin in 1988, 19.3% in 1989

17.2% of ungulates in the Senegal River Basin (1990)

3.8% of wild rodents, notably Rattus rattus, Mastomys huberti, A. niloticus and M. erythroleucus (2000 publication)

Semliki Forest – Semliki Forest virus has been recovered from mosquitoes (Aedes vittatus) and ticks (Rhipicephalus guilhoni) in Senegal.

Tataguine – Antibody toward Tataguine virus is found in 57% of the population.

Usutu – Zoonotic infection by Usutu virus has been identified in Senegal.

Wesselsbron – Seropositive humans were documented in Senegal during 1972 to 1975; and the virus itself has been identified in mosquitoes (Aedes vexans) in the Barkedji region.

West Nile – Seroprevalence rates for West Nile virus of 78.3% to 92% have been reported among horses. Infection of wild birds and dogs has also been identified. Vector mosquito species in this country are thought to include Culex neavei, Cx. tritaeniorhynchus, Cx. modestus, Cx. perfuscus group, Cx. poicilipes, Aedes vexans, Mimomyia hispida, Mi. lacustris, Mi. splendens, Aedeomyia africana and Mansonia uniformis

Yellow fever – Epidemics of yellow fever were reported in Senegal in 1768, 1769, 1778 to 1779 (50 deaths among Caucasians), 1814, 1816, 1828, 1830, 1837, 1840 to 1841, 1844, 1852, 1858, 1863, 1866, 1872, 1900 to 1901 (225 fatal cases) and 1923 to 1927. Aedes furcifer, A. metallicus and A. luteocephalus are involved in the wild vertebrate transmission cycle in this country. Yellow-fever activity among mosquitoes in Senegal has been used to monitor potential human disease in West Africa. Infected mosquitoes were identified during 1976 to 1979, 1983, 1987, 1989, 1990, 1992, 1993 and 2010.  Chronology of recent Yellow fever outbreaks in Senegal:

1965 – 243 cases were reported in Diourbel.

1965 to 1966 – 2,000 to 20,000 cases and 200 to 2,000 deaths were estimated.

1979 – Two French tourists contracted fatal yellow fever in Senegal.

1995 – Cases reported in Ribo-Escale and Guente-Pate Districts (vicinity of Koungheul).

Tularemia Deaths in the United States

Although tularemia is more common than plague in the United States, the case-fatality rate is higher for the latter.  Deaths reported for both diseases have changed little in five decades, with the number of tularemia deaths similar to the number of plague deaths in most years.  See graphs
