A promising step in developing an HIV vaccine will start later this year as the pharmaceutical company, Johnson & Johnson starts testing a vaccine for the virus on human subjects.
Doctors, experts and millions of others around the world have looked for some help against this virus for decades. According to the CDC, almost 1 million people die due to AIDS every year. With new hope for the long-awaited vaccine, that number could drastically change.
Foreign travelers have likely noticed that many countries require yellow fever vaccinations. They might also need proof that a person was vaccinated. Whether that’s a card or certificate, those countries won’t let you enter without the vaccine.
But, what makes this one immunization so important?
For many countries, vaccinated visitors might mean the difference between a manageable virus and full-blown epidemics.
The CDC recently issued a travel alert for Yemen due to the country’s extensive cholera outbreak. The ongoing epidemic is already considered the worst recorded event of its kind in history – and it’s not over yet. Almost 20,000 suspected cases of the illness occurred recently in just one July week.
Overall, the epidemic has affected a considerable amount of the country: 22 out of 23 governorates and 301 out of 333 districts. From the start of the outbreak in October 2016 to June 2019, over 1.8 million potential cholera cases and 3,500 deaths have been reported.
More than 460,000 suspected cholera cases have occurred in Yemen in 2019 alone. There were 19,459 possible cases and 11 associated deaths during the one-week period between the 15th and the 21st of July.
The Philippines recently declared a national dengue epidemic due to their ongoing outbreak. In 2019 alone, the country has confirmed over 600 deaths related to the virus.
Medical experts are urging the population to seek immediate medical attention if they are suffering from any of the key symptoms. Those can include a high fever, uncontrolled vomiting, abdominal pain, or dizziness.
Dengue fever may be a mild illness most of the time, but the cases seem to be much worse here. Not only have they seen an increase in cases, but in severity as well.
If you feel like you’re always swarmed by mosquitoes more so than everyone else at the summer barbecues, you may not be wrong.
For some people, the insects just want more of their blood. But, it’s not a case of bad luck that causes such a problem. Several genetic reasons cause mosquitoes to bite some people more than others.
Before we can understand why mosquitoes bite some people more than others, it’s helpful to know why mosquitoes bite in the first place.
