Дифтерия - это острое инфекционное заболевание, которое, в основном, поражает горло. Симптомами являются боль в горле, лихорадка, головная боль. Есть трудности с глотанием. Появляются беловатые пятна в горле и, если они распространятся на трахею, возникают трудности с дыханием. Ребенок выглядит больным и токсичным. Это заболевание может привести ко многим осложнениям нервов, сердца и почек, а иногда и к экстренной операции (трахеостомия), её, возможно, придется сделать, если горло забивается, и ребенок имеет затрудненное дыхание. Ребенок должен быть госпитализирован в инфекционную больницу на 3-4 недели, и после выздоровления лечится еще дома в течение нескольких недель. Эту болезнь можно предотвратить путем вакцинации детей.

My name is Marina Demchenko. I am 15 years old. I was born in Kharkov and I have been living here all my life.  My mum, dad, grandpa, (my uncle) and I live in a high building in one of sleeping areas of the city. We’ve got a cat, called Alaska. It is only some months old.

 For several years I have been fond of drawing and I like it very much. I love to read novels; it's my favourite genre in literature. I like to watch funny comedies as well as melodramas, but unfortunately, due to lack of time, I can’t (=don’t) do it often. As for my appearance,

 I am thin and short. I have straight brown medium length hair and bright brown eyes. I don’t keep to some particular dress style, but I wear just what I like every other time. As for my traits of character, I think I am very sensitive; I take everything close to my heart.  I can be very emotional but sometimes even whimsical.

I'm pretty responsible and always try to do all the things up to the end. I can say about myself that I’m an ambitious and hard-working person. I am not very sociable, but I’m not quiet either.  I have a few friends with whom I communicate well. Together we all are learning at the same school. I hope that we will continue to be good friends after finishing school.  Now I'm in the 10th grade. (= in grade 10). Our school is not very small, there are about 600 students in it.  At the moment, I do not have any favourite subjects.(or teachers). I try to study well, participate in different competitions and tournaments.    To conclude, I have not decided what I am going to become in the future, so far, but I think it’ll be something connected with design or advertising.
