Health conditions have been a determining factor in cases not only of cholera but of various types of verminoses, high levels of which have been recorded among the indigenous peoples. Other diseases such as influenza and bacterial complications, including diarrhoea and conjunctivitis, continue to be rampant among the indigenous populations. Ninety cases of influenza were recorded among the MyKy in 1994. Since the total population is 63, we conclude that there were at least two outbreaks affecting almost all the inhabitants of the village. In the same year there were 1,611 cases of influenza among the Yanomami.
Pneumonia is one of the complications which appears after an influenza outbreak.
The level among the Rickbaktsa was 6.4 per cent. Among the Yanomami in the Demini, Toototobi and Balawau regions, with a population of 624, there were 159 cases of pneumonia, representing 24.4 per cent. In 1994 it was found that 60 per cent of the Tupinikin were suffering from acute respiratory insufficiency. This represents 410 cases. There were reports of a number of cases of bronchitis and whooping cough among Indians, but the data available to us are insufficient for analysis.
