The pandemic was the work of a 'super-virus' The 1918 flu spread rapidly, killing 25 million people in just the first six months. ... It's now thought that many of the deaths were due to the development of bacterial pneumonias in lungs weakened by influenza.
The WHO recommends strategies on how to prevent malaria transmission by controlling the mosquito population and on how to diagnose and treat malaria infections. There are two main prevention methods: Protective bed nets treated with long-lasting insecticides prevent bites from malaria-infected mosquitoes and kill them.
Edward Jenner. In 1775 Jenner began to study the relationship between cowpox (a comparatively harmless disease) and the more dangerous and disfiguring smallpox. ...

Answer:
To create policies to <em>control or forbid</em> the use of DDT
To create educational programs for the people.
Explanation:
As the individual can not be controlled once it is released, the actions to take abut this problem must be focused on other perspectives. Two main actions would be usefull to improve the condors´ situation:
One of them is to create policies to control or forbid the use of DDT, to reduce contamination in different food and water sources. There are too many animals that get contaminated for feeding on vegetables or other animals grown on perturbed soil, and for drinking polluted water. When these animals die, condor feeds on them and also dies. It is important to avoid using these products that affect the whole biodiversity, including human beings.
The other action is to educate people. It is very important to create educational programs that are accessible to everybody and by which it is possible to teach people about the condors´ biology, feeding behavior, and reproductive rate, among others. People should know that these animals are not dangerous, that they only feed on dead animals, and that their reproduction rate is very low. If people do not have any knowledge about this species and its situation, they will not be able to protect it.
