Trisher, thank you for looking at the link. As far as the WHO is concerned, they have consistently adopted an anti Israel stand. Here are a few links to show the actual situation:http://www.timesofisrael.com/with-gaza-ailing-pa-accused-of-slashing-medical-aid-by-nearly-90/ and
mfa.gov.il/MFA/ForeignPolicy/Peace/Humanitarian/Pages/Israeli-aid-to-the-Palestinians-COGAT-update-February-2016.aspx
As you'll see, the amount of medications sent in by Israel has been cut this year because Abbas, Chairman of the PLO, which had been paying for medical supplies to Gaza, has drastically cut the amount, same for electricity (which the PLO owes Israel huge amount for anyway -the PLO has the money btw). Abbas now says it's up to Hamas to pay for these items and they must, after some 10 years in power (they won't get out), take responsibility for running Gaza and pay themselves. Hamas won't, their leaders prefer to keep vast amounts of what the world gives them. Their leaders have incredible mansions and even more incredible Swiss bank accounts, just as Arafat did.
Re your point about the numbers of Gazans treated in Israeli hospitals being inflated by counting in those accompanying patients, even if true, it's incredible that Israel takes any at all, they aren't obliged to now Gaza is independent of Israel. As Chairman Abbas would say, it's time Hamas took responsibility for his people. As said before, they have been given more than enough money to fund the needs of their society, (including building hospitals).
