Ministry of Public Health urged to discuss 21-day detention and keep an eye on 3 covid mutants The vaccine formula must be adjusted every 1 year.

On February 15 at the Ministry of Public Health (Ministry of Public Health) Asst. Prof. Opas Puttacharoen Head of Clinical Emerging Diseases Center Chulalongkorn Hospital, the Thai Red Cross Society, said the first Thai patient to travel from Tanzania and was found to be infected with the COVID-19 virus. South African species. At this time, the symptoms improved gradually. Reduced oxygen delivery The virus is naturally mutated. Only mutations in humans or animals May cause faster mutations than normal mutations

Asst. Prof. Opas said that the outbreak in various places. Around the world, the nature of the viral endemic species may be selected. Currently, common and wary of species are reported worldwide. It is suggested that three strains that may have problems are not normal viruses. But a virus that has mutated

1. Species B.1.1.7 (GR, G), first discovered in England As of September 2020, most of them are in England. It is distributed in the United States. And other countries in Europe already By mutant positions as special positions Is on the surface of the virus The virus has better properties of human cell surface binding, and in the laboratory it is found that the virus is effective in dividing the virus, therefore the virus in the nasopharynx is very infectious. In addition, now there is evidence from many British hospitals It was found that the strain was associated with slightly higher rates of morbidity and mortality.

2. Strain B.1.351 (GH, G), first discovered in South Africa By October 2020, the virus has better captured cells. More easily infected May be able to escape Phu Mu better escort May affect the effectiveness of the vaccine decreases. Because it is a vaccine developed using the original strain Many countries have tested the vaccine. It was found that the effectiveness of the vaccine was reduced when someone infected with this virus. The species is now found in many countries of South Africa.

3. Strain P.1 (GR) First discovered in Brazil in December 2020, it was found that the human plasma or the immune system actually binds to these viruses. When compared with these unchanged viral strains.

“The fear of this South African strain is that it has a reduced impact on the vaccine response. But not the effectiveness of the vaccine, it cannot be prevented at all. However, an updated vaccine must be developed every 1-2 years, similar to influenza vaccination. As for the severity of this species, there is no information on whether it will be more severe than other species, it must be followed up, the terms of treatment are no different. There is no information on which strains require more treatment than others. The 3-day genetic decoding of Southern Aphika strains is currently undergoing a change in testing methods, taking 1 day. Only at the spot that is found to be changed frequently, not the whole line of genetics Said Asst. Prof. Opas.

Asst. Prof. Opas said that in Thailand The mutated species is detected by people traveling from abroad. Was exhausted at a state-provided quarantine facility Which the Chulalongkorn Emerging Disease Center has to detect various species From the countries of interest to watch, namely South Africa, England and Brazil, to keep Thais from being exposed to the mutant infection. This will affect the future use of the vaccine. The Ministry of Agriculture has discussed plans to increase the quarantine date for those who originally traveled from countries in South Africa to 21 days because it is a risk point. But the quarantine cannot be increased for everyone, although the lineage has already been distributed in other countries, but Thailand will count the date of commencement of their journey from South Africa, including a 21-day detention measure, along with the detention.

“Confirmed that the strains that have spread in Thailand do not yet have mutated species. Is also a species that comes from Myanmar But inhibiting human-to-human transmission will prevent new strains from forming. That may be a species of Thailand itself With different properties Which now the Center for Emerging Diseases There is constant monitoring. But still not worrying Because the epidemic in Thailand is not long enough to mutate the virus, but there is still constant monitoring, ”said Asst. Prof. Opas.

side Dr. Chao Tasan Namwat, MD. Director of the Emergency Health and Disease Control Division, Department of Disease Control, discusses the situation of the COVID-19 epidemic. In the event that it is related to Pornpat Market, Pathum Thani Province, that there is a good trend The first 400 participants showed 10% infection and later, when the proactive test in the 1,400-1,700th group, the infection decreased 5-9%, indicating that it was in Better direction But did not trust Also closely monitor the symptoms

Dr. Chao Tasan said that including proactive checks in the Phetchaburi market, which is related to Pornpat market. It shows that we continuously monitor cross-site. If infected person is found, it will be reported to the public honestly. May the people trust In the case of infection among the security personnel of Chulalongkorn University, there have been no further reports of infection for 4 days, the most recent being found on Feb. 11.
