Infected people remain contagious from the appearance of the first symptoms until 3–5 days after the rash appears.

German measles is an unrelated condition caused by the rubella virus.

Symptoms

The classical symptoms of measles include a fever for at least three days, and the three Cs—cough, coryza (runny nose) and conjunctivitis (red eyes). The fever may reach up to 104° Fahrenheit/ 40° Celsius. Koplik's spots seen inside the mouth are pathognomonic (diagnostic) for measles but are not often seen, even in real cases of measles, because they are transient and may disappear within a day of arising.

The characteristic measles rash is classically described as a generalized, maculopapular, erythematous rash that begins several days after the fever starts. It starts on the head before spreading to cover most of the body, often causing itching. The rash is said to "stain", changing colour from red to dark brown, before disappearing.

[edit] Diagnosis and treatment

Clinical diagnosis of measles requires a history of fever of at least three days together with at least one of the three Cs. Observation of Koplik's spots is also diagnostic of measles.

Alternatively, laboratory diagnosis of measles can be done with confirmation of positive measles IgM antibodies or isolation of measles virus RNA from respiratory specimens. In cases of measles infection following secondary vaccine failure IgM antibody may not be present. In these cases serological confirmation may be made by showing IgG antibody rises by Enzyme immunoasay or complement fixation.

Positive contact with other patients known to have measles adds strong epidemiological evidence to the diagnosis.

There is no specific treatment or antiviral therapy for uncomplicated measles. Most patients with uncomplicated measles will recover with rest and supportive treatment.

Some patients will develop pneumonia as a sequela to the measles. Histologically, a unique cell can be found in the paracortical region of hyperplastic lymph nodes in patients affected with this condition. This cell, known as the Warthin-Finkeldey cell, is a multinucleated giant with eosinophilic cytoplasmic and nuclear inclusions.

[edit] Virology

Measles virus (MV) is an enveloped, nonsegmented negative-stranded RNA virus of the Paramyxoviridae family.

[edit] Transmission

The measles is a highly contagious airborne pathogen which spreads primarily via the respiratory system. The virus is transmitted in respiratory secretions, and can be passed from person to person via aerosol droplets containing virus particles, such as those produced by a coughing patient. Once transmission occurs, the virus infects the epithelial cells of its new host, and may also replicate in the urinary tract,

My Favourite Sport Tennis

We all need exercise. This is true for young people (in their teens) as well as for adults. Even if you don't plan make sports your main occupation. This is my opinion and I feel like it is true.

As long as I can remember myself I was always keen on tennis. I love this sport with its old noble traditions, though myself never dreamed of becoming anything more than an amateur.

I watch closely all tennis competitions and championships. There are a lot of them, but my favourite championship is Wimbledon because old tennis traditions remains there as they are. Some of the most well-known Wimbledon champions are: John McEnroe, Boris Becker, Steffi Graf, Monica Seles. My dream is to get a chance to watch at least one of them playing.

And meantime I play tennis with my friends. It is also a great opportunity to socialize with people who have similar interest (as any sport I suppose).

Держать себя в форме

Every morning I take a shower. I brush my teeth 2 times a day, morning and evening. This is very important for my health.Sport activities helps me to be strong and healthy.

During the winter I go skiing and skating. I spend much time outdoors

Such time spending allows me to not to be ill in winter. It brings a lot of joy and fun. We have a great time with my friends. Every summer we spend 2 weeks with my parents at the sea. We swim in the sea. Eat fresh fruit and tasty food. It is my favorite habit.

Weather

The weather is a subject we can always talk about. It often changes and brings cold and heat, sunshine and rain, frost and snow. One day is often unlike the next. In summer the sun shines, often there is no wind and there are no clouds in the sky which is blue and beautiful. We can see stars and the moon at night and people like walks, outdoor games and sports in the fresh air.

When autumn comes, the days become shorter and colder. It gets dark earlier and often heavy clouds cover the sky bringing rain with them.

Sometimes there is heavy rain, so that an umbrella or a raincoat is necessary if we don't want to get wet through. Then you can hear people say, "What bad weather! When is this rain going to stop?" Many people then catch cold and must go to bed. Then a fire at home is so pleasant. At last frost and snow come.

Fields, forests and houses are covered with snow and rivers and lakes with ice. But spring again brings sunshine and warm winds. Sometimes it snows but snow will not remain long, it will melt in the warm sun. Spring will bring bright sunshine, green grass and flowers.

We usually say: "A nice day", "Not a bad day" or "It's nice weather for the time of the year" if the weather is fine.

We can say: "It looks like rain", "It looks like snow" of "It's bad weather" when the weather is bad.
