Be careful to protect your skin in typhoon days.

The typhoon hit and the city was seriously waterlogged. Dr. Clove hereby reminds you to pay attention to protect the skin soaked in water and guard against the following diseases:

Contact dermatitis (allergy)

Long-term sewage soaking can elute sebum that protects the skin, swell and fall off the outermost stratum corneum, and destroy the original barrier function of the skin. In addition, waterlogged sewage with mud and sand, skin contact is likely to cause allergy, namely contact dermatitis. Especially the original eczema, atopic dermatitis, urticaria and other skin allergic diseases of the population, contact with sewage is likely to aggravate the disease, and even form systemic allergy.

Manifestations: Erythema and papules appear in the parts exposed to sewage, with mild desquamation and obvious pruritus.

Nursing: After contacting with sewage, be sure to clean it in time. Local cleaning should be paid attention to where there is allergy, but do not use soap or hot water with too strong alkalinity to stimulate skin again.

Treatment: First of all, it is important to get rid of allergens and avoid contact with sewage. Second, it is antiallergic treatment with topical hormone ointment. If systemic allergy develops, it may also require systemic medication, oral administration or injection of antihistamines under the guidance of doctors.

Cercariae dermatitis

Sewage not only brings silt, It may also bring Schistosoma japonicum cercariae that originally stayed in farmland. Animals infected with schistosoma japonicum, such as cattle and ducks, discharge excrement into paddy fields. Schistosoma japonicum eggs can pollute paddy fields, enter the body of vertebral snails in paddy fields, develop into cercariae and enter the water. At this time, if there is a flood disaster, it can spread everywhere along with the water flow. If you meet people, you can drill into the skin to cause dermatitis.

Manifestations: cercariae dermatitis often occurs in the lower leg, showing that after contacting with sewage containing cercariae, skin pruritus occurs within 15-30 minutes, followed by the formation of millet-sized red papules, which expand into mung bean size after a few hours, or form small blisters. Because cercariae cannot grow and develop in human body, it dies after about 2 hours, so it will not cause visceral diseases.

Treatment: Cercariae dermatitis is not a simple allergy. In addition to relieving itching, sterilizing and preventing infection, some insecticidal drugs, such as clomitron ointment, need to be used under the guidance of doctors.

Erysipelas/cellulitis

Erysipelas is a bacterial infectious disease occurring in lymphatic network. It is mainly caused by type A hemolytic streptococcus and is often secondary to the original tinea pedis (commonly known as beriberi).

Cellulitis is a bacterial infectious disease that occurs in loose connective tissue under the skin. It is mainly caused by Staphylococcus aureus. People with tinea pedis, A usually pale dip between the toes, Or a small broken wound, These tiny skin lacerations may not cause serious consequences in a dry environment, but urban waterlogged sewage contains a large number of pathogenic microorganisms, including Streptococcus haemolyticus and Staphylococcus aureus. These bacteria invade the subcutaneous lymphatic network through these tiny lacerations, which can cause erysipelas or cellulitis.

Manifestations: Erysipelas of lower limbs is often manifested as high edema of local skin, and there is a clear dividing line between the red and swollen part and the surrounding skin. Cellulitis often has sunken edema and unclear boundary of redness and swelling, but both diseases have the manifestation of increased skin temperature at the affected part. If blood routine examination is carried out, it will be found that the number of white blood cells increases, with neutrophils as the main factor.

Treatment: After finding the disease, you need to go to the hospital as soon as possible for antibacterial treatment to avoid septicemia.

Septicemia

In addition to erysipelas and cellulitis treatment is not timely, may lead to septicemia, skin lacerations may not only expose lymphatic vessels, but also may expose blood vessels. Sewage visibility is low, it is difficult to judge a foot to step on what, if unfortunate stepping on sharp objects, scratch bleeding, bacteria also have a certain chance to invade the blood, forming septicemia.

Manifestations: Septicemia often occurs within a few days after local infection and suppuration occur, and further systemic poisoning phenomena such as high fever and chills occur.

Treatment: Septicemia progresses rapidly and requires medical treatment as soon as possible in order to select effective antibiotics, otherwise life may be endangered.

Safe Travel to sum up, ordinary citizens should try their best to avoid travel during waterlogging, and even if they travel, they should not underestimate the harm of sewage: they should wear long rain boots or all-body water trousers to avoid trauma and isolate contact with sewage; If accidentally contact with sewage, after returning home should take advantage of no allergy or other strange, carefully wash with soapy water; After iodophor disinfection is applied to the broken areas, keep them dry. If you find any abnormalities, you should seek medical treatment in time. Finally, I would like to pay tribute to my friends in the anti-Taiwan front line and protect myself!
