The death rate from influenza rose markedly in the 1990’s, federal scientists reported. The explanation, they said, is that a greater proportion of the population is elderly and thus particularly susceptible to flu. There was an average of 36,000 flu deaths a year in the 1990’s as compared to 20,000 a year in previous decades, the investigators, from the Centers for Disease Control and Prevention, reported in the Journal of the American Medical Association. Ninety percent of influenza deaths were in people 65 and older, said Dr. Keiji Fukuda, the principal researcher for the study. But Dr. Fukuda and his colleagues reported that the virus was especially deadly in people over 85, who might be up to 32 times more likely than those 65 to 69 to die from a flu infection.
The researchers also concluded that there were large numbers of deaths among the elderly from another virus, respiratory syncytial virus, known as R. S. V. As many as 78 percent of the 11,000 peopl

1. The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years. It is considerably higher in urban and industrial areas than in rural districts. There are many possible causes, but it is still controversial which are most blameworthy. Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air (smoke particles, smog, exhaust fumes), and the smoking of cigarettes and cigars.
2. Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits. Among heavy smokers — 21 to 30 cigarettes per day — the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers. It is expected the death rate among women will increase as the present high rate of smoking among women has its effect.
