Dengue fever usually occurs in the rainy season from May to November every year.Dengue fever has the main clinical manifestation of high fever (like other viral fevers) and hemorrhagic with many different forms, severe form with shock due to decreased circulating blood volume.Mosquitoes that cause dengue fever are becoming more and more persistent.Dengue fever is characterized by high fever, headache, pain in both eye sockets, congested skin, petechiae under the skin, bleeding gums, nosebleeds.To identify dengue fever, it is necessary to test for blood with decreased platelets, test for NS1 antigen (+), test for IgM ELISA antibody (+).According to experts, the mosquitoes that cause dengue fever are becoming more and more persistent, even some mosquitoes are already resistant to drugs.There should be places, even though they have sprayed mosquito killers, still have dengue fever.Dr.Pham Thi Khoa, former official of the National Institute of Malaria and Parasitology, said that when investigating the current situation of mosquitoes causing dengue fever, they found that areas where the number of mosquitoes is only 0.3/. Households are areas with low/almost no chance of getting dengue.To prevent dengue fever, Dr.Pham Thi Khoa said that the first rule is to kill all the swarms, not to let the water jars, jars or bonsai pots have water.Potted plants in many families that have not changed water for a long time can also be a suitable place for salt to grow.If there are ponds, ditches around the house, etc., Hantephot or Apat larvicide must be used to sprinkle on the area with water once a week.Dengue mosquitoes are only active during the day, so prevent mosquitoes from entering the house by limiting opening the door early in the morning.This is the time when mosquitoes are most active.Between 10am and 4pm, when the sun is shining, mosquitoes are less active.Around dusk, mosquitoes have the habit of flying into the house to find shelter, so it is also limited to open at this time.GS.Bui Cong Hien, of the Vietnam Entomological Association, said that mosquito species, especially those that transmit dengue fever, often cause outbreaks in densely populated places with poor sanitation.Mosquitoes that transmit disease like to lay eggs in clean water or rain, even a small bowl of water, a vase of flowers, a dish of moisture-proof water in the flower room, a small puddle in the roof, balcony... even Even in the dish tray in the kitchen there is still water.It can be said that without water, mosquitoes do not exist.Another feature to note is that larvae and archers (the pre-adult stage of the mosquito) usually live only in fresh water (low salt concentration) and must constantly come to the surface to breathe.Therefore, to kill larva and bow, one can use salt mixed in water or use cooking oil, lubricants... to create a film on the water surface.Dr.Pham Thi Khoa said that to prevent dengue fever, it is possible to use mosquito incense to keep mosquitoes out of the house.However, the mosquito scent only makes the mosquito faint or fly away, but the mosquito does not die, so when using the mosquito scent, it must be used continuously for at least 1 week.After burning incense, the house must be swept to remove the fainted mosquitoes.When there are no mosquitoes in the house, then stop burning incense.In addition, you can use herbal mosquito repellent solutions to clean the house, which also have a very good anti-mosquito effect.For children, you can use herbal anti-mosquito sprays that are safe for health.Chemical spraying must be done by health authorities, the principle is to only spray in areas where outbreaks have arisen, not to spray chemicals for prevention because it more or less affects health, especially children. .If your family has conditions, it is possible to install anti-mosquito doors in all doors and openings.This helps prevent mosquitoes from entering your home, protecting all family members.If you have a hobby of growing ornamental plants, instead of closed potted plants, you should intersperse them with useful mosquito repellent plants such as five houseplants, lemongrass, basil, basil, mint, fragrant pine... You can grow it in a window, door or in the garden as you like.Website of the Ministry of Health (MOH) Copyright by the Ministry of Health No. 138A Giang Vo - Ba Dinh - Hanoi Tel: 0246,273.2,273 |Fax:0243.8464.051Email: banbientap@moh.gov.vn Specify the source of the Ministry of Health's web portal or http://moh.gov.vn when re-issuing information Tel: 0246.273.2.273 |Fax:0243.8464.051
