The world is in a well being disaster because of dengue. For a couple of months now, well being authorities such because the World Well being Group (WHO) have been warning in regards to the improve in instances on the earth: greater than 8 million instances have been registered worldwide in the one 4 months, most of them based mostly in America. .

It is about the biggest dengue epidemic in historical pastas stated Professor Iván Darío Vélez, founding father of the Program for the Research and Management of Tropical Illnesses -Pecet- of the School of Drugs on the College of Antioquia and researcher emeritus on the Ministry of Science, Expertise and Innovation.
The causes of this viral illness unfold all around the world local weather change – which is resulting in rising temperatures and shortening the life cycle of mosquitoes Aedes aegypti, so in much less time the mosquito can transmit the virus -; Phenomena resembling El Niño are additionally extended (drought can favor the expansion of mosquitoes), a migration that facilitates the unfold of the virus, because the 4 serotypes of the virus DENV-1, DENV-2, DENV-3 and DENV -4. current in the identical place, growing the danger of an infection.
One more reason is poverty and lack of entry to primary providers, which classifies dengue among the many uncared for tropical illnesses.
In Colombia, efforts have been made to cut back dengue. In reality, scientists have carried out very properly. Instance: in 2022 Bello introduced that he was the primary metropolis in Latin America to regulate dengue. Professor Ivan Darío Vélez led the mission Mosquito phrase program in alliance with Pecet to contaminate dengue-transmitting mosquitoes with so-called micro organism Wolbachia which prevented them from spreading the virus within the Aburrá Valley and thus lowering instances in cities resembling Medellín, Itagüí and Bello.
The mission was profitable, issues began to go downhill. Now it’s this management that has saved the world away from a disaster just like the one in different areas of the nation resembling Valle del Cauca, Cali, Tolima, Huila, Santander and around the globe: in accordance the researcher, the mosquito is reaching locations it had not reached earlier than within the tropical zone at greater altitudes. Mosquitoes have been reported at over 2,300 meters above sea degree.
Though data has been unfold within the media that Medellín and Antioquia are on alert for dengue, the reality is that it might be a lot worse. “We ought to be in an epidemic, a minimum of much like the final one in 2016 the place there have been 17,000 instances within the metropolis. Now, though dengue instances have doubled 200% within the nation, in Medellín there ought to be greater than 20,000 instances now and they don’t attain 1,000, because of the organic management program experiential. We achieved the biggest historic reductions in comparison with all the nation” stated the researcher.
Other than organic management, researchers have thought of different methods to combat dengue. Professor Iván Darío stated that Pecet is presently growing merchandise resembling wall coverings that kill mosquitoes when utilized; They have already got a patent, together with Pintuco, to promote paint with pesticides. Now, maybe essentially the most profitable breakthrough, and already permitted, is Qdenga, the quadruple vaccine to forestall the virus, developed by the Japanese pharmaceutical firm Takeda with the assist of facilities different researchers resembling Pecet, who performed an vital position in its growth.
Options of Qdenga
It’s a quadrivalent vaccine designed to offer immunity to the 4 serotypes of the dengue virus: serotype 2 being essentially the most aggressive. The biologic requires the applying of two doses in three months and is designed to stimulate an immune response towards the 4 serotypes. In easier phrases, they need the physique to acknowledge the virus and be capable of combat it.
This vaccine collects the envelope of serotype 2 and provides antigens from the opposite three to realize full safety; It’s an injection that’s given subcutaneously (ideally within the higher arm), It’s indicated for folks between 4 and 60 years previous. as scientific trials haven’t but been developed with different age teams.
“With this injection the immune system can acknowledge the virus, assault it and neutralize it in order that the illness doesn’t seem. That is the one vaccine we have now in the intervening time that’s already available on the market in different international locations resembling Brazil and right here in Colombia we’re shut,” defined the researcher.
This vaccine contraindicated for folks beneath 4 years previous and over 60 years previous, as a result of there will not be sufficient research. Additionally for these with hypersensitivity to biologically energetic substances or to a earlier dose of Qdenga; for folks contaminated with the human immunodeficiency virus (HIV), folks with immunodeficiency or who’ve obtained immunosuppressive therapies resembling chemotherapy, and pregnant and lactating girls.
As well as, this vaccine It isn’t 100% efficient.. Though their outcomes have been profitable, some folks could not develop an immune response towards all serotypes of the virus; and the corporate assures that it isn’t recognized in the intervening time whether or not the shortage of safety may trigger dengue deeper.
“It’s endorsed to proceed private protecting measures towards mosquito bites after vaccination. Folks ought to search medical consideration in the event that they develop dengue signs or warning indicators of the illness,” the pharmaceutical firm wrote.
This doesn’t imply that it isn’t an excellent scientific advance. “It is vitally vital to have a management device like this vaccine now. Dengue is changing into so widespread that it’s essential not solely to develop vaccines, but in addition medicines and extra preventive measures,” stated the researcher.
In Colombia, the Nationwide Institute for Meals and Drug Analysis (Invima) the Japanese vaccine agreed in November 2023and presently, the pharmaceutical firm is discussing with private and non-private organizations to start out buying and selling within the nation.
“Takeda is in discussions with the Ministry of Well being and Social Safety to supply it in vaccination plans. Governments want political will for any such growth. This virus is extra transmitted in low-income populations and these vaccines are normally costly. The federal government should make investments and handle the folks. We as researchers attain some extent however it’s the duty of the administration to make these choices,” he says.
In keeping with the Facilities for Illness Management and Prevention, the commonest symptom of dengue is fever together with nausea, vomiting, rash, eye aches and pains (normally behind the eyes), muscle ache, joint ache, and ache within the eyes bones. If there’s a warning signal, seek the advice of a physician.
