"Only prolongs existence"
Preventing malaria stops people from suffering from the sickness, prevents grief from the death of that person (often a child), and boosts economies by decreasing sick days and reducing the burden on health systems
Remember that most malaria cases are not fatal.
It kills ~350,000 people a year. The fatality rate isn't as important as the total deaths.
because it only prolongs existence
You could also minimize existence.
I don't have particular charity recommendations, but for preventing human suffering:
What charitable foundations would you recommend, with the goal of minimizing suffering? fighting malaria does not make sens, because it only prolongs existence https://forum.effectivealtruism.org/posts/LAuQXwnykrMC73CvW/morality-for-the-radical-pessimist I'm basically repeating this topic because I didn't get an answer
Animal charities. Most suffering in the world happens in farms. See recommendations for where to donate by Animal Charity Evaluators.
To address extreme suffering in humans then consider:
Some caveats:
Bednets do also prevent suffering and are very well evidenced so are still an option. See HLI's research on this here.
There are reasons to not be a 100% negative utilitarian. See Toby Ord's essay on this here.

Fully endorsed. And I would add that if you don’t mind more speculative, harder to evaluate interventions there are organizations working on risks of future astronomical suffering like the Center for Long-Term Risk, and organizations working on wild animal suffering like Wild Animal Initiative. For more measurable impacts I don’t have much to add to weeatquince’s excellent suggestions.
+1 on OPIS.
You state this like it's a fact but it's heavily dependent on how you compare animal and human suffering. I don't think this is a given. Formal attempts to compare animal and human suffering like Rethink Priorities' Animal Welfare Estimates have enormous error bars.
Worthy being cautious in a world where ~10% of the world live on <$2 a day.
