Relapsing Fever in Africa

A CAJM article on relapsing fevers in Africa during the 1950's.The relapsing fevers, broadly classified into the louse-borne and tick-borne varieties, are characterised clinically by an initial pyrexia of 2-4 days’ duration, followed at intervals of a few days by successive relapses, and caused by spirochaetes (Horrelia) which are present in the circulating blood in the acute stages of the illness. Classification and nomenclature are not yet well-defined in the spirochaetes which are morphologically indistinguishable but biologically separable. The spirochaete is specifically referred to as Borrelia recurrentis (or B. obcr- meiri) in the louse-borne form. In the tick- borne form a variety of names has been given to the responsible spirochaetes, largely indicating the geographical region of occurrence or the worker who identified them, thus, Borrelia duttoni is the spirochaete of Central and Southern Africa, and B. venezuele.nsis, B. aegyptica, B. berbera, B. kochii, B. tiovyi. are names of the spirochaetes found elsewhere

The incidence of 'climate asthma' in South Africa: its relation to the distribution of mites

A survey has been made of rhe regions of South Africa, from rhe low coasral alrirude to the inland regions of high altitude, in regard to the presence and number of mires in the house dust in connection with 'climate asthma'. The data obtained confirm that the nl/mber of mires in rhe house dust depends upon the relative humidiry of the region involved. A number of anomalous findings are reported from inland and coastal regions where unexpectedly high or low mire counts are recorded. They are accounted for, however, by the high or low relative humidiry of the area concerned due to the local adjoining warm or cold ocean-currents. This confirms the relationship of rhe incidence of 'climate asthma' to the factor of relarive humidity. The mite most commonly found in the house dusts in South Africa is Dermatophagoides pteronyssinus. Other mites found include Euroglyphus maynei, Chortoglyphus domesticus and orher species. Dermatophagoides farinae mites were recovered in scanty numbers from the house dust of only 2 towns

Book Note: Why Love Leads To Justice: Love Across The Boundaries, by David A.J. Richards

MUCH FEMINIST SCHOLARSHIP HAS GRAPPLED with the concept of love in its many forms. Modern love has been understood as a manifestation of harmful patriarchal values, a “curse”2 that confines women to rigid gender norms of femininity and passivity.3 However, love has been reclaimed and reconceptualised by some feminists as a powerful force for resisting these patriarchal norms and encouraging self-realization among women, men, and others.4 David A.J. Richards’s Why Love Leads to Justice makes a valiant effort on the latter understanding.5 His thesis is simple: love leads to justice.6 In particular, love that is transgressive, which crosses the boundaries of the existing “Love Laws,” leads to justice.7 He uses Love Laws to refer broadly to law aimed at criminalizing and otherwise prohibiting sexual and loving relations between certain classes of people. The book narrows in on two kinds of transgressive love: adultery and gay and lesbian love. Using the intimate stories of prominent artists and social activists of the nineteenth and twentieth centuries, Richards draws on the linkages between their personal and public lives to demonstrate a reciprocal empowerment between the two domains. Life in love across legal boundaries is shown to be an act of resistance to patriarchal injustice. At the same time, the stories demonstrate how transgressive love has allowed for the healing of moral injury done to the protagonists by Love Laws designed to suppress and marginalize them. Groundwork is laid for these ideas in the first chapter by looking at the adulterous relationships between George Henry Lewes and Marian Evansknown widely by her penname, George Eliotas well as Harriet Taylor and John Stuart Mill
