Following the announcement that North Korea is investigating its first possible coronavirus case, authorities reminded foreigners living in Pyongyang to abide by anti-coronavirus measures, the Russian embassy there said on Wednesday.
North Korea's foreign ministry circulated a notice on Tuesday telling foreigners not to leave the city, hold large meetings, and to wear masks, among other rules, the embassy said in a post on its Facebook page.
North Korea declared a state of emergency and introduced tougher curbs against the coronavirus, state media reported, after it locked down the town of Kaesong, on the border with the South, to tackle what could be its first publicly confirmed infection.
State television reports showed people in protective gear disinfecting buildings and surfaces around the capital city of Pyongyang.
Temperature checks using infrared thermometers, hand-washing facilities and sanitizer dispensers were in place in public locations including shopping malls, restaurants and hotels, the World Health Organization said in a statement.
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
