'Mission of Mercy' by Larry Spiegel

Realising that the dog-fight with the flying monster has used up most of their plane's fuel, the astronauts and humans set about locating a new supply. But after Bill and Jeff set off in an abandoned gorilla truck, Nova falls seriously ill, and Brent diagnoses her symptoms as Acute Infectious Streptococholus, a highly contagious lung disease – which will kill her within seventy-two hours. In a race against time, Judy leaves in the plane and heads for Ape City, hoping that Zira and Cornelius will be able to help make a serum that will cure Nova…
