At any time throughout the infection, urticaria with an infectious cause may develop. In youngsters, 80% of urticaria instances have an infectious cause rather than an allergic cause.

Other causes of non-allergic urticaria include heat, cold, exertion, and pressure on the skin. There are also instances of chronic urticaria, which can go on for longer than six months with no clear cause.


Although it shares the same origin as urticaria, this illness is a more severe form of allergy because it affects the mucous membranes and deeper layers of the skin.

As a result, it may result in swelling of the eyes, lips, tongue, and respiratory system.

It is crucial to keep in mind that this is a bad situation that might progress to anaphylactic shock owing to glottis oedema or severe asthma and cause respiratory distress.

Those who have previously experienced urticaria, which is re-expressed to the substance to which they are allergic, are more likely to develop angioedema.

Anyone who experiences hives together with eye or lip oedema should consult a doctor very away.

Contact dermatitis

An instance of skin irritation brought on by close contact with an irritant is contact dermatitis. Contact dermatitis comes in two different varieties.

  • The most frequent is brought on by skin-to-skin contact with naturally irritated individuals.
  • The second type is when a patient comes into touch with substances to which they are allergic.

Bijouterie, particularly those that include metals like nickel, chromium, cobalt, gold, toxic plants, topical antibiotics, latex, fragrances or cosmetics, rubber, leather, enamels, alcohol, and even scented soaps are among the most frequent causes of contact that result in dermatitis.

An itchy, burning rash that may also be accompanied by tiny blisters or skin splits are sign of contact dermatitis. Contact dermatitis often only affects the portions of the skin that were in contact with the hazardous material; it does not affect the rest of the skin.

If the patient is no longer in contact with the substance that caused the rash, dermatitis typically goes away after a few days. Corticosteroid ointments may be required in situations when the reaction is more severe.

Atopic dermatitis – Atopic eczema

Atopic dermatitis, commonly known as atopic eczema, is a skin condition that affects many children. It typically appears in folds, such as the neck, ulnar fossa, and popliteal fossa, which is a portion of the back of the elbows. One place that can be often affected in infants is the face. Dermatologists can prescribe effective over-the-counter eczema medications to treat red areas.

Although the exact origins of atopic dermatitis are unknown, it is most likely a mix of immune system deficiencies and dry, irritated skin. It is crucial to keep in mind that psychological stress can make injuries worse. It’s great if you invest time and effort into learning more about atopic eczema as it might be difficult to diagnose. People frequently find it difficult to tell if they have atopic eczema because it frequently resembles a benign rash.

Atopic dermatitis develops within the first five years of life in about 85% of cases. Atopic dermatitis manifests as pruritic eczema, which typically comprises thick, scaly, and hidden plaques.

Atopic eczema is a chronic condition that fluctuates between times when the rash gets worse and times when it gets better. When children reach adulthood, almost 40% of them spontaneously relapse with the illness.

Since the mosquito injects its saliva so that it has an anticoagulant effect in the blood it suckers, the bites of this species of bug frequently result in skin allergies. The material that specifically triggers allergic reactions in people is mosquito saliva.

The reaction to the bite is typically mild and localised, with the most typical sign being a tiny crimson elevation in the skin accompanied by severe itching.

The bite’s symptoms often occur within 20 minutes and might last up to 2 days before going away. The reaction to a mosquito bite is typically more severe and strong the more sensitive its saliva is.

Estrucous prurigo, a disorder caused by excessive sensitivity to mosquito bites, can occur in some persons.

They typically develop several scarlet and itchy lesions following a single bite, as if numerous mosquitoes had stung them simultaneously in various locations on their bodies. In some situations, the injuries could last for a month.


Seborrheic eczema, commonly known as seborrheic dermatitis, is a common and irritating skin condition. An area of the skin with a lot of sebaceous glands develops a chronic inflammation known as this type of dermatitis.

Seborrheic dermatitis is not a true skin allergy, despite the fact that it is brought on by the immune system’s response to the presence of a specific type of fungus on the skin, and shares many characteristics with other dermatitis of allergic origin, including the appearance of plaques and itching.


Mange also referred to as scabies, is a skin condition brought on by the Sarcoptes scabies mite. It is an infectious illness that can be swiftly passed from person to person who lives in the same home or among children in childcare facilities through close physical contact.

The most common sign of scabies is a generalised itching of the body, which is typically worse at night. Little patches or reddish, embossed balls are the classic lesions of scabies. Sometimes the lesions are so little that they might be hidden by the scratches that result from the severe itching.

Hands, fists, elbows, armpits, nipples, areas around the navel, genitals, knees, buttocks, thighs and feet are the areas most commonly afflicted by the illness. In general, the areas that youngsters typically attack include the backs, the head, the palms, and the bottoms of the feet.

Intertrigo (candidiasis of the skin)

The skin condition known as intertrigo candidiasis is brought on by the fungus Candida and mostly impacts intertriginous tissues. the regions of the body where two skins come into contact, such as the groyne, armpits, scrotum, lower portion of the breasts, or space between the toes.

These folds are particularly prone to the development of intertrigo because they are warm, damp locations that encourage the growth of microorganisms, particularly fungi.

Skin intertrigo candidiasis appears as well-reddened regions with light scaling and little red spots surrounding them. These lesions, which are found in areas of skin folds, may sting or burn.

In newborns, candidiasis of the skin frequently affects the diaper area.

Dermatophytosis (skin mycosis) (skin mycosis)

The term “dermatophytosis” or “ringworm” are other names for the superficial mycoses of the skin. The two genera Trichophyton, Microsporum, or Epidermophyton of dermatophyte fungus are responsible for dermatophytosis. Unlike candidiasis, which typically results in intertrigo, dermatophytosis is a separate type of fungal infection.

Dermatophytoses can affect the scalp, feet, beard, nails, trunk, and limbs, among other body parts. Contagious skin fungal diseases can spread by contact with linens, towels, or regular clothing.

The primary signs of cutaneous mycosis are localised redness and irritation. The first signs of ringworm are typically a plaque or reddish, oval-shaped patches, whose centres normally clean up over the course of a few days. The lesions often grow in the shape of circles if untreated.

The fungal infection of tinea cruris, which affects the groyne, can also manifest as a red plate on the inner thighs.

Pityriasis rosea

Another typical cause of red skin spots with severe itching is pityriasis rosea. Although the exact aetiology of the disease is unknown, research suggests that several members of the human herpesvirus family, including human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7), may be responsible. the same ones that cause abrupt exanthem or infantile roseola, an entirely distinct illness in youngsters.

Pityriasis is a skin rash that is probably viral in origin, however, it is not contagious.

The rash of pityriasis rosea

The rash typically starts as a single round, a pink lesion that is the size of a coin and has minor peeling. A few days later, smaller, fresh lesions that are similar to the first but smaller start to appear around the groyne and on the trunk. These very itchy red spots on the skin can take one to three months to go away. New lesions may develop throughout the body during this time.

With time, the lesions take on a ring-shaped appearance with a lighter core and reddish, peeling edges.
