The Duke and Duchess of Sussex are midway through their first major Royal tour since they tied the knot in May, and it comes only days after they announced Meghan’s pregnancy.
On the 11th day of their landmark trip, the Royal newlyweds travelled to Tupou college to dedicate two rainforests to The Queen’s Canopy, a forest conservation project that encompasses 53 Commonwealth nations.
The school is located in one of these forests.
Meghan’s attendance comes as a surprise as she skipped her husband’s visit to a forest in Fiji as a precautionary measure against mosquitoes.
Mosquitos can carry the Zika virus, which can then be passed on to humans through their bites.
The World Health Organisation classified Tonga in March as a “Category 1” risk region for the disease.
This means it is an “area with new introduction or re-introduction with ongoing transmission” of the virus, which can cause serious birth defects, including microcephaly.
But the Duchess appeared relaxed and unconcerned today and even decided to wear a short-sleeve blue dress.
Meghan has been wearing outfits with long sleeves and lower hemlines during her tour, and according to reports it was to lower her risk of mosquito bites.
She has also been wearing light-coloured clothing, which is believed to be less attractive to the flying pests.
Meghan wore a darker colour palette when in Australia, and has noticeably lightened her wardrobe for her visits to Fiji and Tonga.
Despite her appearance at the school, it has been claimed Meghan has been taking precautions to prevent mosquito bites.
The mum-to-be attended a welcome reception and dinner with King Tupou VI and Queen Nanasipauʻu in Tonga on Wednesday evening and she was spotted with shiny, wet arms.
Professor James G. Logan, Head of the Department of Disease Control at the London School of Hygiene and Tropical Medicine, told People.com the Duchess was wearing insect repellent.
During the visit to Tupou College, the boys choir also sung a comedy song that included buzzing noises.
The aim was to frighten off any mosquitos that might have been around the Duke and Duchess of Sussex.
