Young men and women of childbearing age who do not have immunity should be careful!

• Most of the cases are men in their 20s to 50s, who are said to have low rubella antibody titers, but there are also women who have not been vaccinated.
• In particular, pregnant women and women who may become pregnant are at risk of fetal congenital rubella syndrome. Therefore, it is necessary to be careful to prevent infection at work and at home.
• For more information,

  Please refer to the.

Protect pregnant women and babies from rubella with immunizations

• Rubella infection in early pregnancy can also infect the fetus with the rubella virus, resulting in the birth of a baby with congenital rubella syndrome.
• Rubella vaccination cannot be given during pregnancy. To prevent congenital rubella syndrome, it is important for family members (especially partners) to be vaccinated.
  Family members of pregnant women living together (husbands, children, etc.) , women in their late teens to 40s (especially those who wish to become pregnant or are likely to become pregnant ) , women who have just given birth (in early pregnancy, the antibody titer for rubella is low ) people) should be vaccinated against rubella.
  Nakano Ward subsidizes rubella antibody tests and vaccination costs for adults. For more details, please proceed to subsidies for adult rubella antibody tests and vaccinations, and MR (measles and rubella mixed vaccine) vaccination .
• Don't forget to immunize your child with MR (measles and rubella mixed vaccine) .

About the increase in syphilis

(Micrograph: Courtesy of the Tokyo Metropolitan Institute of Health and Safety)

• The number of syphilis patients continues to increase, especially among women in their 20s and 30s.
• Syphilis is a systemic disease (a sexually transmitted disease ) transmitted by kissing or having sex with someone who has the pathogen (Treponema syphilis).
  Both men and women should be especially careful about infection through sex without a condom.

symptoms

• A few weeks to a few months later, a lump may appear in the genital area, lips, or mouth, or the lymph nodes at the base of the crotch (groin) may swell. It disappears (sometimes there are no symptoms).
• Several months to a year later, symptoms such as swollen lymph nodes throughout the body, fever, malaise, joint pain, and a characteristic generalized rash called “barasin” may appear.
• Even if the symptoms disappear, syphilis will not go away unless treated with antibiotics.
  If left untreated, it can cause serious brain and heart complications, and syphilis infection in pregnant women can lead to congenital syphilis.

treatment

• Syphilis, if caught early, can be cured with antibiotics for about a month.
• If you are infected with a sexually transmitted disease such as syphilis, you are much more likely to be infected with HIV (AIDS virus).
• If you have any concerns or suspect that you have been infected, please seek medical attention as soon as possible!

About the epidemic of infectious gastroenteritis

(Electron micrograph of norovirus: Tokyo Metropolitan Institute of Public Health)

• Infectious gastroenteritis is prevalent mainly from winter to early spring.
  Especially in the case of infectious gastroenteritis caused by norovirus, it is necessary to be careful as it may become a large-scale epidemic in places such as nursery schools and elementary schools.
  The status of the epidemic of infectious gastroenteritis in Tokyo is available from the Tokyo Metropolitan Infectious Disease Surveillance Center. Please proceed to infectious gastroenteritis (mainly norovirus) .
• Hand washing is the most effective way to prevent infectious gastroenteritis caused by viruses such as norovirus and rotavirus.
  Always wash your hands after using the restroom, before preparing food, and before eating.
• When dealing with vomit or diarrhea, make sure the room is well ventilated, wear disposable gloves and a mask, disinfect with bleach (such as haiter), wipe thoroughly with paper towels to prevent scattering, and then bleach again. Disinfect well, including the wide area around it, with an agent (such as Haiter).
  It is highly contagious, so be careful not to spread the contamination.
  Disinfectants using bleach should be used at a concentration of 0.1% (approximately 60 times) for floors and 0.02% (250-300 times) for doorknobs and sheets.

Sentinel medical institutions and number of reports per sentinel

• In Nakano Ward, there are six pediatric sentinel medical institutions that report the number of patients with Category 5 infectious diseases and the number of influenza patients subject to sentinel monitoring under the Infectious Diseases Law.
• In addition, 4 sentinel medical institutions for influenza, 1 sentinel medical institution for ophthalmology, and 2 sentinel medical institutions for sexually transmitted infections (STIs) have been designated.
• There are 264 sentinel points for pediatrics, 419 sentinel points for influenza, 39 sentinel points for ophthalmology, 55 sentinel points for sexually transmitted infections (STIs), and 25 sentinel points for primary care throughout Tokyo. (As of January 2021)
• The number of reports per sentinel (0.0 person per sentinel) is obtained by dividing the number of patient reports (number of sentinel reports) each week by the number of sentinel medical institutions, which is a measure of the epidemic situation.
