It’s been ten days since Meghan Markle and Prince Harry revealed that they are expecting their first child. Since then, Meghan has not let her pregnancy stop her from continuing on with her 16-day tour of various royal countries, and she is currently in Fiji with her husband.

Many worried about Meghan making stops in Fiji and Tonga, as both nations are known to have had outbreaks of the Zika virus, which can cause serious birth defects in babies should a pregnant woman suffer from it. Royal fans can breathe a sigh of relief, however, as it has just been revealed that Meghan is taking several precautions while in Fiji to ensure that she will not come down with the virus.

Despite the heat, Meghan has been seen wearing long white dresses with long sleeves, which is what doctors advise women to wear for protection from the virus because it makes it more difficult for mosquitos to bite. Mosquitos are the insects who carry the virus, and they are attracted to dark colors.

“I’m sure that they will have sought travel health advice in terms of protective methods in terms of mosquito bites. There is a lot you can do to minimize risks,” said Professor James G. Logan, Head of the Department of Disease Control at the London School of Hygiene and Tropical Medicine.

“Wearing long sleeves and baggy clothes will help,” he adds. “Mosquitos can even bite through jeans so if the clothing is loose it’s much harder for the mosquito to bite. Wearing light-colored clothing can help as these mosquitos are often attracted to dark clothing. It also helps you spot them, if you see a dark mosquito on a light piece of clothing. Generally the risk is low but, there is still a risk and you need to weigh up how to protect yourself and make sure you are fully informed.”

Logan went on to advise that Meghan wear a very specific type of insect repellant for protection.

“The advice would be to wear a repellent which contains an active ingredient and wear that repellent all day and all evening,” Logan said. “You have to put the repellent on like a hand cream. You have to really rub it in. If you squirt it on like a perfume, that won’t do anything because the mosquito will find a bit that’s not covered. A spray or a lotion is fine but really rub it in and reapply it often. There are four active ingredients, one of the main ones is DEET and it’s safe to use that during pregnancy.”

We hope that Meghan is able to protect herself from this dangerous virus during the rest of her royal tour!
