This includes countries country facing the Zika virus, causing concerns – as the newly weds have previously hinted at their plans for children.
A royal source said of Meghan and Harry’s Royal Tour that the smitten couple will have “taken advice at the highest level before deciding that they were happy to go ahead and plan the trip”.
Another source told the Daily Mirror “every precaution will be taken” ahead of the Duke and Duchess of Sussex’s trip.
They added: “The Royal couple’s health is naturally of the utmost importance.”
Many are wondering if the couple will be looking to have children soon.
If they do there are a number of confusing royal rules that will apply to them.
This includes the fact that they will not be called prince or princess, even though their cousins are.
Prince William and Kate Middleton’s children are Prince George, four, Princess Charlotte, two, and Prince Louis, two months.
Why won’t Harry and William’s childen get the same honour?
Royal Expert Kelly Lynch told Express.co.uk: “Meghan and Harry’s children will be Lords and Ladies, according to the Letters Patent George V issued in 1917.
“What’s odd about this rule is that future children of the the Duke and Duchess of Sussex will be the grandchildren of the heir to the throne, who will then become king (Prince Charles).”
This means that Meghan and Harry’s children will be prince and princesses eventually but they will have to wait.
The 1917 Letter’s Patent decreed that great-grandchildren born during a monarch’s reign would not have the title prince or princess unless they are the first male grandchild of the male heir.
So therefore under these rules only Prince George would have that title.
The rest of Prince William’s children would be Lady Charlotte and Lord Louis.
However, the Queen amended the letters patent to include all of his children in Janaury 2013.
However, she did not do the same for any children of Prince Harry.
When the Queen passes away all of her great-grandchildren will then become grandchildren of the new monarch King Charles III.
They will then be known as prince and princess.
Another strange rule that applies to Meghan Markle and Prince Harry is peerage laws.
They mean that only a male child can inherit their title.
Peerage laws in the UK are still rather outdated with only males being able to inherit one.
