Tick- and Mosquito-borne Diseases: Trends in the United States

The following data are abstracted from Gideon and the Gideon e-book series. [1]  Charts were created using an interactive tool driven by over 30,000 base graphs in the program. [2]

Chart 1 contrasts trends for reported incidence of Lyme disease and Rocky Mountain spotted fever (RMSF).  Note that while rates of Lyme disease in 2016 are 15-fold those reported in 1987, those of RMSF increased by a factor of seven.  The number of fatal cases for both diseases have remained similar in recent years (i.e., the relative case-fatality rate of Lyme disease has decreased)

Chart 2 summarizes incidence data for a variety of tick-borne and mosquito-borne infections.  Note that rates of Ehrlichiosis, Anaplasmosis, Babesiosis, Jamestown Canyon virus infection and Powassan encephalitis have increased since the year 2000.  The incidence of LaCrosse encephalitis has decreased, while that of California encephalitis is largely unchanged.

Charts 3 and 4 demonstrate that incidence and reported deaths for Western equine encephalitis, Eastern equine encephalitis, St. Louis encephalitis and West Nile fever have changed little in recent years.

HTLV Infection in Australia

The following background information on HTLV infection in Australia is abstracted from Gideon and the Gideon e-book series. [1,2]

The first report of adult T-cell leukemia / lymphoma related to HTLV-1 infection in an Australian Aborigine was published in 1991.  Three such cases had been reported in non-Aboriginal Australians as of 1993. The first report of tropical spastic paraparesis related to HTLV-I infection in an Australian Aborigine was published in 1993; and the first report of HTLV-II infection in Australia was published in 1994.

The risk of a transfused patient developing HTLV-I infection from un-screened blood was estimated at 1 in 370,000, and the risk of developing HTLV-I disease at 1 in 9-to-15 million (1993 to 1995).  The following screenshot summarizes published sero-prevalence surveys of HTLV infection in Australia. (primary references available from the authors).

Malaria in Trinidad and Tobago

The following background data on malaria in Trinidad and Tobago are abstracted from Gideon and the Gideon e-book series. [1.2]

Trinidad and Tobago was certified “malaria-free” by WHO in December 1965.

84 cases of malaria were reported during 1968 to 1986 (29.8%  due to Plasmodium falciparum)

213 cases were reported during 1968 to 1997 (40% P. falciparum)  These figures included 164 cases imported during 1968 to 1977 – 48.8% from Africa.

118 cases were reported during 1989 to 1998 (33.8% P. falciparum)

Incidence data for malaria are depicted in the following graph.  Peaks reported during 1966 and 1994 to 1995 reflected local outbreaks (see below).

 

The local potential vectors are Anopheles aquasalis (coastal swamps), An. bellator (bromeliad malaria),  An. homunculus,  An. albitarsis (rice fields) and An. oswaldoe (small running streams).

Outbreaks of autochthonous malaria:;

1966 – An outbreak (38 cases) of Plasmodium malariae infection was reported on Tobago

1990 to 1991 – An outbreak (10 cases) of Plasmodium vivax infection (vector Anopheles aquisalis) was reported in Icacos village on the southwestern peninsula.  The index patient had arrived from Venezuela

1994 to 1995 – An outbreak (42 cases) of Plasmodium malariae infection (vectors Anopheles bellator and An. homunculus) was reported in a forested area of Navet-Biche, on the northeast coast.  13% of patient contacts were found to be seropositive for malaria.
