(CMC): Health authorities are urging that students be allowed to wear long trousers and long-sleeve shirts at schools in an effort to help combat the dengue fever outbreak, which has claimed two lives, including a nine-year-old student.

St. Vincent and the Grenadines is experiencing its worst outbreak of the mosquito-borne viral illness in eight years, with 274 cases confirmed by laboratory tests as of Monday.

Chief Medical Officer (CMO), Dr. Simone Keizer-Beache told a news conference that correspondence had been sent to the Ministry of Education advising that it consider allowing children, students to wear long pants and long sleeves so that they would decrease their exposure.

“If you have light colours, long sleeves, long, pants, the mosquitoes can’t bite you as easily…. I know there are some schools already where that is allowed,” she told reporters.

Earlier this week, the Ministry of Health said that it was investigating four suspected dengue deaths and that by Tuesday, it had had been able to confirm two of the cases.

During the news conference on Tuesday, Dr. Keizer-Beache was asked whether there is any link between the reopening of schools on September 7 and the upsurge in dengue cases.

“In terms of the link, I think it has to do more with the fact that this is a day-biting mosquito. Typically a day-biting but we are seeing later; that it can bite earlier in the morning and late in the evening but the main thing is during the day; so wherever you work or wherever you are.

“So the children have been in schools, but something else we want to look at, the last big outbreak was in 2010 and 2012, which means that anybody born after 2012 have not had significant exposure. So we have what we would call a virgin population, persons who have not been exposed to dengue and so don’t have immunity to it, and that would be in the 8-year-olds and lower.

“So we have a combination where you have person where they are during the day and also you have a large population of people who have never been exposed to dengue and that’s in the eight-year-old and under age group,” she said.

The dengue outbreak comes at the same time as the coronavirus (COVID-19) pandemic and although the island has no active cases of pandemic, dengue and COVID-19 have similar symptoms during the early stages.

The COVID-19 protocol calls on schools to record students’ temperature daily and to refer them for medical attention according.

“With the COVID protocol, we are taking temperatures and we had asked all schools to develop a close relationship with their healthcare providers in their districts and so they should have a relationship where, if a child has a fever, they can communicate with the healthcare provider in that area…,” Dr. Keizer-Beache said.

“We want to, however, stress that … especially with children, the window from going from not feeling so well to being very ill is very short. So that anybody with a fever, we need parents, guardian, teachers, everyone to be very aggressive about seeking care.

“Right now, our institutions are very full. The polyclinic in Buccament (Monday) had 100 patients in one day, and this is being reported throughout the system but we want persons to still seek care. Ask a question and this is how we are going to respond together.”

The CMO said that her ministry will hire an additional 10 doctors and six nurses to help to treat patients.

But Dr. Keizer-Beache said that a “shared responsibility” would help to determine how long the outbreak lasts.

“And it is not just the Vector Control Unit, and they are the ones who would go and do the fogging and advise. But what we are doing here today, we are suggesting, we are pleading, we are asking that everybody take responsibility, which means we decrease exposure.

“And how do we do that? We ensure t that we are not collecting — we are not breeding mosquitoes, which is against the law, actually, and there is fine for it. But we are asking persons to take care and we will take care and together we will deal with this. So we decrease exposure by decreasing the source so we move the mosquitoes, we are protecting ourselves.”

Dr. Keizer-Beache said it is important for persons to clear bush around their home and workplace so as to reduce mosquito breeding sites and to use mosquito nets while sleeping.

“We have nets in the hospital too. So if we all work together, we can end this much sooner rather than later,” she said.
